Selecting a Clear Primer for Oil Portray

A transparent primer lets the color and texture of the canvas or wooden present in your portray. We have a look at 11 manufacturers to see how clear they’re, what they really feel like to color on, and extra.


 

Most oil work on canvas or panel are ready with white gesso after which the entire floor is roofed with paint so that you just now not see the white floor. In the event you don’t wish to cowl the entire floor of your canvas or wooden panel with paint, however as an alternative wish to go away small or massive areas of canvas or wooden displaying as a part of the portray, then you might wish to prime your floor with a transparent primer as an alternative of a white one. This may enable the color and texture of your floor to be seen in order that the grey-brown of the linen or the color and grain of the wooden can develop into a part of your portray.

Making use of a primer onto your canvas seals the floor and prevents oil paint from coming into contact with the linen or cotton fibres which might slowly be broken by the oil, changing into darkish and brittle over time. Some clear primers also can act as a stiffener for stretched canvas, so it’ll wobble much less. Wooden panels don’t must be sealed from oil for longevity however priming will give a greater floor to color on, by making it much less absorbent and night out the absorbency of the wooden which might in any other case have totally different quantities of absorbance between the grain strains and the wooden between them.

At Jackson’s now we have a fantastic collection of white primers however we even have a reasonably good collection of clear ones. I’ve finished some testing to seek out out the traits of every one. The three major issues most artists can be keen on are: how clear it’s, if it’s a slick or absorbent floor as a result of that impacts the way it feels to maneuver the paint round, and the way good a price it’s. I reply these questions and likewise check out different traits together with ease of utility, drying time, and the way nicely it blocks oil penetration, in addition to many others.

Matt mediums or rabbit pores and skin glue are generally used as sizes beneath a white gesso/primer, however for those who do one or two extra coats, they will then be the bottom as nicely, which many artists do. So along with merchandise offered as clear primers, I added a collection of matt mediums in addition to rabbit pores and skin glue, for a complete of 11 merchandise to check. You’ll be able to learn in regards to the phrases ‘measurement’, ‘floor’, ‘gesso’ and ‘primer’ in Dimension, Primer, Gesso and Floor Defined.

I didn’t take a look at PVA as a result of most artists select to make use of it to economize, so they might be utilizing a budget stuff. Artist grade PVA will not be a less expensive different to clear primer. There are over 50 various kinds of formulations of PVA (Polyvinyl Acetate) and just a few are of a ok high quality to make everlasting work as a result of they’ve low acidity, retain flexibility, and have low color change. PVA not made particularly for artists will deteriorate – yellowing, clouding, shrinking and peeling – and is to be averted if you need your work to stay in good situation.

Testing totally different utility strategies, thicknesses, and layers. And making swatches to check paint on when cured.

 

Issues I Needed to Know In regards to the Utility of Every Primer

  • Color when making use of – is it clear or milky so you may see the place you’ve finished.
  • Viscosity – is it the thickness of cream, honey, or yoghurt. And a.) does thicker imply that it’s going to fill within the open weave of linen higher, b.) will extra fluid be smoother with much less noticeable brush marks, c.) will extra fluid cowl extra floor space.
  • Circulation – how far does the identical quantity of primer go on wooden and on canvas.
  • Thinning with water – do they must be thinned and the way a lot.
  • Self levelling – do brushmarks clean out when left.
  • Sanding – can it’s sanded for max smoothness.
  • Shrinkage – does it crack because it dries for those who put it on thickly.
  • Contact-dry drying time – time to be touch-dry for making use of a second or third coat. All acrylic primers have to treatment for 48 hours earlier than being painted on.
  • Odour – some folks complain of robust smells of some primers.
  • Ease of use of container- bag, bucket, bottle – and what retains the gesso from drying across the rim so the subsequent time you utilize it, it isn’t stuffed with crumbs you need to pick.
  • Worth- evaluating value per 100 ml for good protection – how far does it go, what number of coats are wanted.

 

Issues I Needed to Know In regards to the Bodily Traits of Every Primer

  • Transparency – how clear is it over brown linen and a picket panel. Is it extra clear if utilized in 3 skinny layers somewhat than one thick one.
  • Color change of floor – does it darken or lighten the wooden or linen.
  • Flexibility – does it crack whenever you roll the canvas for storage or whenever you re-stretch it, so it ought to solely be used on a inflexible floor.
  • Texture – chalky, gritty, clean, silky, plasticky, slick. And one is obtainable in a collection of textures: clean, medium, coarse, very coarse.
  • Sheen – is it matt, satin, or gloss when dried.
  • Absorbency – a.) are you able to wipe off oil paint or does it stain. b.) does the comb drag or slide easily. c.) does oil paint dry matt as a result of the oil has been sucked up. d.) does non-absorbent imply worse paint adhesion of the paint to the primer.
  • Adhesion – 2 sorts a.) does the primer stick nicely to the substrate – on wooden and on canvas. b.) does dried paint stick nicely to the primer.
  • Oil paint penetration – does the primer seal the canvas or does oil paint penetrate via to the again, each thick oil and a fluid oil wash.
  • Yellowing – does the polymer yellow over time – generally acrylic gels do, a lot of PVAs do, I let it age for 5 months at midnight as a result of I’m judging the color from the rolled up linen I used to check flexibility.

The 11 Clear Primers

I’ve given them every a quantity and when speaking about totally different attributes, I take advantage of the quantity for effectivity. On the backside of the article, every primer is listed individually with all of all its attributes.

1. Jackson’s Acrylic Fluid Gloss Medium

2. Jackson’s Acrylic Fluid Matt Medium

3. Schmincke Clear Primer

4. Golden Matte Medium

5. Golden Fluid Matte Medium

6. Liquitex Skilled Clear Gesso

7. Winsor & Newton Artists Acrylic Clear Gesso

9. Lascaux Sirius Acrylic Medium Matt

10. Michael Harding Non-Absorbent Acrylic Primer, Clear

11. Handover Rabbit Pores and skin Glue – 12:1 dilution

 

Absorbency

Until you’ve gotten particular necessities, you often wish to select a primer that’s someplace in the midst of the spectrum between utterly non-absorbent (feels such as you’re portray on moist glass, so slick that it received’t seize the paint off of the comb) and the opposite excessive of too absorbent (seems like portray on masonry, so absorbent that it received’t unfold simply and that the oil is sucked out of the paint and it’s left with out sufficient binder). You need it slick sufficient that it has some wipeability and absorbent sufficient for good adhesion. Some folks desire a much less absorbent floor (smoother and extra sealed) due to the convenience of brush motion or as a result of they wipe again, utilizing subtraction rather a lot as a part of their course of, and a few like a really absorbent floor as a result of they like their brush to really feel like it’s sticking and dragging the floor extra and is much less slick, the place the floor grabs the paint from the comb. Of the absorbent surfaces, texture can differ from feeling a bit chalky, to feeling like sandpaper. Typically not absorbent can imply poor adhesion, however none of those 11 primers had that drawback. Some artists like a cheesy floor like primer 1 & 2 or one like RSG the place the paint sinks into the bottom and feels prefer it merges with it. None really feel chalky. And even after they appear to be they’re tremendous absorbent, none really feel like they’re wicking oil away as can occur with some common gessoes.

I then rubbed a chunk of tape down firmly and pulled it away. The paint was not affected.

 

Sanding

I used to be stunned by how helpful just a little little bit of sanding was:

  • It provides a a lot smoother floor with simply 20 gentle strokes with a sanding sponge
  • Not a lot mud comes off to fly round, the mud fills within the holes within the linen weave, apart from the rabbit pores and skin glue whose holes are huge.
  • It will get whiter / extra opaque on a few of them, and never on others
  • Some primers profit from two coats on linen, then a lightweight sanding to take away the sticking up tough fibres of the linen after which a 3rd coat is utilized. Those that benefited most had been numbers 3, 6, 7, 9, 10. The others don’t profit, and a few worsen.

I used a sanding sponge with a medium wonderful grit and did the 20 strokes in all instructions. The unprimed linen subsequent to the take a look at patch, when sanded, grew to become very white. I feel it may be the linen fibres that poke above the primer that’s what is being sanded white. The linen may be coated in starch or one thing related, I didn’t wash/rinse/moist the linen (I’ve heard of some artists that do). Some artists sand their linen canvases between all of the layers of white gesso, as a result of it’s bushy and the hairs poke up in a extra apparent method after they’ve been wetted. Even a lightweight sanding can actually enhance the floor.

How Many Coats of Primer You Want

The advantages of a second coat of primer on stretched linen:

  • No oil penetration
  • A fair color of floor, not streaky
  • Even absorbency
  • A much less absorbent floor than one coat
  • If utilized thinly, the color / transparency is often not a lot totally different, so it’s value doing a second coat
  • The identical quantity of primer utilized as 3 skinny layers can be clear, but when utilized unexpectedly as one thick layer can be cloudy and opaque.

There was an enormous distinction between the quantity of primer want for the picket panel and the stretched linen. 1 ml of primer gave a thick coat in a 7.5 cm sq. on the picket panel. But it surely took 2.5 ml to provide even a skinny coat to the identical measurement sq. of linen. It’s because as you’re employed the primer into the fibres to coat them, heaps will get pushed to the again, and it additionally tries to replenish the areas within the weave, so it takes greater than twice as a lot primer for linen as for wooden.

 

Odour

I checked the odour as a result of some folks complain of the robust smells of some primers. These had been all delicate or had a medium-mild odour. None have a powerful or noticeable odour. This contains the rabbit pores and skin glue. See Rabbit Pores and skin Glue: Preparation, Makes use of And Options to learn extra in regards to the delusion of the odour of RSG.

Delicate = 1, 2, 6, 8, 10 and 11.
Medium = 3, 4, 5, 7, 9.

 

Drying Time

All acrylic primers have to treatment for 48 hours, but when they develop into touch-dry shortly, you are able to do a second coat sooner after which go away it for the 48 hours. In the event that they dry too quick you might not be capable of unfold it nicely or get it into the weave by brushing in all instructions. None of those dried too quick. I utilized a skinny layer to stretched linen canvas and timed them till they had been touch-dry.

The 4 with a lot of thick creamy texture poking via to the again had been the slowest to dry, besides Golden Matt Medium which shaped sufficient of a pores and skin to not be moist on high so you might do a second coat sooner. Even with a great deal of brushing in all instructions, the primary layer wasn’t very even on a few of the primers so you might want a second coat to be sure to don’t have streaky protection.

That is the contact drying time of the primary coat to permit making use of of a second coat, if you wish to.

1h = 1, 2, 3, 11
2h = 5, 8
2.5h = 4, 10
3+ = 6, 7, 9

 

Flexibility

I painted out lengthy stripes of every on a sheet of linen after which rolled it up tightly and left it for five months. After I unrolled it none of them cracked with the flattening out. #1 caught to itself a bit, as a result of it’s cheesy, and quantity 2 caught to itself simply barely.

Codecs Out there

The primers are available a wide range of codecs and sizes: bottles, pots, a pouch and dry granules that you’ll want to combine with water and heat up. Like white gesso, any container the place the primer can dry out on the higher partitions inside or within the threads of the container, can create dried chunks that need to be picked out of the floor. The codecs which might be least prone to have this drawback are the squeeze bottles and the pouch – these are those with small openings and fewer drying out that happens. And the squeeze bottles are simply actually tidy and handy.

 

Yellowing

It most likely wants an extended time to check for yellowing as a result of it occurs slowly in acrylic. However trying on the colors over 5 months, none modified noticeably.

11 – 4-6 coats received darker on each linen and panel like the fabric had been wetted.

 

Dried Color of Clear Primers on Gentle-coloured Picket Panel

  • Some in a second coat are darker whereas some are whiter.
  • After I say gritty, I imply – for those who run your finger tip over it, it’s like superfine sandpaper. Whereas clean seems like a varnished desk high.
  • All however 1 & 2 had been amazingly matt, no shine, like they had been invisible.

1. One coat: semi gloss, some darkening. Two coats: very shiny, exhibits brush marks, not darker than one coat, however is then a cheesy floor texture.

2. One coat: matt, some darkening. Two coats: semi gloss, no brush marks, identical darkness as one coat, very clean.

3. One coat: very clear, invisible. No change with second coat.

4. One coat: clear and darkening. Two coat: barely smoother, barely extra absorbent.

5. One coat: clear almost invisible. Two coats: sightly smoother, extra absorbent. Beautiful end.

6. One coat: clear, almost invisible. Two coats: identical as one coat, very gritty and absorbent.

Stiffness

Testing utilizing clear primer as measurement to stiffen the canvas for much less wobbling:

In no way, the least stiff, very smooth: 10.
Some stiffness: 1, 2, 3, 6, 7, 8.
A bit stiffer than most: 4 & 5.
Second most stiffest, fairly stiff but nonetheless foldable: 9.
Probably the most stiff, very stiff. Although least in a position to be creased and folded and bounce again, misplaced its stiffness on the creased fold: 11.

Rabbit Pores and skin Glue is great for stiffening the linen. The sharp fold proven is on the fringe of the place an space of RSG begins on the canvas.

Michael Harding Clear Primer is the least stiffening. The realm with the primer folds over simply as softly as the realm of linen with out primer.

 

Observing the Absorbency of the Primers by How Matt the Paint Grew to become

All primers on panels in a single and two coats, had been absorbent sufficient for the thicker oil combination to dry matt or semi-matt, besides 4, 5, 11. On linen, the oil remained the shiniest on 11, though it’s the least wipeable so most absorbent. The remaining all dried semi-gloss. Quantity 5 was the subsequent most shiny.

 

Brushing onto Stretched Linen

The primers for the oil penetration checks on the stretched linen have one coat of two.5 ml of primer in a 7cm sq. of linen, brushed nicely in each instructions so it pushes some to the reverse aspect of the linen. All have a second coat of 1 ml on the decrease half of the sq.. The second coat didn’t push via to the again as a result of it was already fairly sealed. It was left to treatment for 48hrs earlier than testing oil paint.

These pictures present the again of the canvas whereas the primer is moist. Every one pushed via to the again a unique quantity. That is simply to provide you an concept of the way it handles when you’re making use of it, and to point out they’re totally different.

Brushing Onto Picket Panel

They had been all pourable. The extra fluid primers (1, 2, 3, 5, 11) had been quick to brush out, as was the thickest (quantity 10), the remaining took much more brushing to coax out to cowl the identical quantity of panel. Utilizing a moist brush helped with quantity 7. Quantity 10 says to ‘Shake Effectively’, which produces a lot of bubbles, however they brush out. It’s the just one that lightens the wooden, somewhat than darkens it. Would most likely be invisible on cotton canvas. It’s also sticky like honey.

Testing Oil Paint in Two Thicknesses (a Wash and Thick Physique) on Linen and on Picket Panel

For each linen and panel, I brushed on two thickness of oil paint – an oil wash and a thicker oil combination. The oil paint combination I used for testing is Jackson’s Artist Oil Phthalo Blue with Jackson’s Quick-drying Medium Gloss and just a little Gamsol to create a medium-heavy consistency. The skinny wash combination has much more Gamsol.

 

Oil Paint on Primed Wooden

All primers add a gritty really feel to the easily polished wooden floor, besides 1, 2 and 5. The outcomes of testing oil paint on a picket panel with two coats of primer are listed underneath every primer. All bled at the very least just a little into the wooden grain, besides quantity 6, so for those who don’t need that then you will want at the very least three coats for the remainder of them. I additionally did the identical take a look at on an space of unprimed wooden – as anticipated, the paint bled/feathered and left an oil halo, and each thicknesses of paint stained and couldn’t be wiped away in any respect. Quantity 6 and seven had been so absorbent that they had been nearly as laborious to wipe away because the unprimed space.

 

 

 

 

Oil Paint on Primed Linen

1. Paint was clean and slick on only one coat of primer, good wiping.

2. Paint was clean and slick on two coats of primer, even higher with three. Good wiping. No brush drag or grittiness.

3. Advantages from three coats. Good wiping. No brush drag or grittiness.

4. I might distinctly really feel the weave of the canvas. Advantages from three coats. Good wiping. No brush drag or grittiness.

5. One coat was staining. Sealed nicely at two coats. Third not an enchancment. Not gritty. Wiped away nicely.

6. One and two coats are staining and with third coat nonetheless unable to wipe away a lot. Very absorbent, has brush drag.

7. Left little white balls that needed to be picked and disregarded the floor earlier than testing the paint. There was some wipe away doable with three coats. Gritty and really absorbent, just like quantity 6.

8. Every layer turns into extra sealed. 3 coats may be very absorbent however with some wipe away. Gritty, not slick.

9. Heavy oil paint skips over the weave. Very absorbent at three coats and turns into a bit extra sealed feeling, however by no means wipes away. Gritty.

10. Sealed at two coats, not nice wipe off however higher wipe-off at three. Not gritty, not too slick.

11. Very absorbent and marking till greater than 4 coats. After that it turns into smoother however nonetheless fairly absorbent. Uniquely, it has tiny sparkles on the floor.

 

Oil Paint Penetration to the Again of Clear Primed Stretched Linen Canvas

4 of the primers sealed the canvas sufficient with one coat that there was no oil penetration via the canvas (primers 2, 3, 4, and 10). The opposite seven ranged from very slight penetration to a reasonable quantity. All of them had been sealed completely after a second coat. I additionally present an instance of the oil halo you get on unprimed linen.
