Can you use latex paint over oil based primer?
Yes you can. You have two choices to do this. First would be to wash the surface, sand and then clean the sanding dust off. You may then apply your latex paint over the
Let's break it down. You cannot use water-based paint on top of oil-based paint. You can use oil-based paint on top of water-based paint. You can use a water-based primer on top of an oil-based primer.
If you put latex paint over oil, you'll just end up with that fruit roll-up look all over your house because they just can't adhere. Since they're not compatible, they won't form a good bond. 15-30 days after painting, you'll even be able to peel that paint right off after getting the surface wet.
In addition, water-based paint is preferred when covering an oil-based product because it has a faster drying time and resists fading in the sunlight for exterior applications.
Use latex primer under latex paint; while it may be dry to the touch in just 30 minutes, wait a good 3 hours before proceeding with paint. Use oil-based primer under oil-based paint, and give that all-important primer coat 24 hours to fully dry.
You totally can! Often wall paint is also on acrylic base so there's no problem at all. I would say it's better because you will have a smoother base so it'll be easier to paint.
If the paint does NOT come off, it is oil-based paint and you will need to prime the surface with a bonding primer before applying latex paint. The primer can be latex, but it has to be a product that is made to prepare the surface and help with adhesion and that says “bonding” on the label.
Using water-based or acrylic paint when painting over oil-based paint is likely to cause peeling or chipping because those formulas don't bond well with the naturally glossy surface of oil-based paint.
Oil-based Primer
These primers work with both oil paints and latex paints, making them very versatile and applicable to a wide variety of surfaces. Wood (painted or unpainted), steel and other metals, and surfaces with existing paint, such as interior and exterior walls are ideal surfaces for oil-based primers.
If the paint doesn't come off, you are likely dealing with an oil-based product. Next, you will want to properly prepare the surface before applying new paint. So, if you have identified oil-based paint, we recommend that you lightly sand the paint until you have dulled down the glossy sheen.
Can you use latex paint over oil based kilz?
There's absolutely no reason why you can't put a water-based acrylic paint on to of an oil-based primer. It hiss hold up perfectly well and the layers won't bleed into one another.
While some oil-based paints can get applied without the need for a primer layer, we always recommend that all areas to get painted are properly cleaned and sanded for maximal adhesion.

In short, you will typically need 2 coats of primer for most painting projects. Apply primer liberally and allow to dry fully before applying your final coat of interior paint.
Two coats of an oil-based primer are recommended on unfinished wood: The higher solid content in primer can fill the pores, level the surface for painting, and mask any knots in the wood.
Placing Latex Over the Oil Primer
Oil-based primers take at least eight hours to dry. You may have to lightly sand the primer over smooth wood surfaces with 180-grit sandpaper to provide an easier bonding surface. Be sure to wash away any dust caused by the sanding and allow the area to dry before adding your paint.
Latex paints will not stick to oil based paints. The exception is that an oil based primer may accept any kind of top coat paint. For that reason, an oil based primer is recommended to be applied over any oil based top coat, then a water based paint may be used as a top coat.
Since 2004 in six states, the EPA has banned Oil Based Paints. They include: New York, New Jersey, Pennsylvania, Virginia, Maryland, and the District of Columbia. Why? The EPA is banning the paint to reduce ground-level ozone.
You should never paint over oils with acrylics. The reason for this is that acrylics are essentially a plastic and not breathable. Oils, however, release gases over time. If you paint acrylics on top of oil, the released gases will cause the acrylic paint layer to crack and flake off as the gases try to escape.
As a whole, to paint over oil-based paint without sanding a high-bonding primer has to be used and the surface, that will be painted, needs to be intact and clean. Simply apply the high-bonding primer directly to the surface and let it dry. Then apply the paint to the freshly prepared surface.
Sometimes it can be difficult to determine if it? s safe to apply oil paint over latex paint, but we assure you, overtime it will ruin your surface. Due to the flexible qualities of latex paint and the brittle characteristics of aged oil paint, it can eventually split and crack the painted surface.
Can you paint latex paint with oil-based paint?
Painting with an oil based paint over latex is OK but doing the reverse will cause you grief for many years to come since any further coats of paints applied will stick to the latex only.
Cons of oil-based paint. The main disadvantage of oil-based paint is the strong odour, which is quite invasive, and the paint does take significantly longer to dry, so care is required with any dusty work, and ensuring that nothing is likely to make contact with the wet surface.
Water-based paints dry faster than oil-based paints because they're thinner, and easily affected by airflow. A thicker paint (like two-in-one paint and primer) takes longer to paint (and dry) because it's significantly thicker. Sheen is another aspect to consider.
Water-based paint dries significantly more quickly than oil-based paint. It may take 6-8 hours for the paint to dry to the touch, and you may need to wait up to 24 hours before applying a second layer.
Oil-based primers are better than latex primers at sealing nail heads, covering knots in bare wood, and blocking tannin bleeding and other stains. They are also better for sealing bare window muntins that will be covered with oil-based window putty.
Oil-based primer is typically used for projects that require a tight seal. Water-based primer works well for indoor areas that are less likely to contact water. Oil-based paint off-gases more VOCs than water-based paint, making oil-based less idea for indoor use.
To help achieve a consistent appearance with your final coat, when painting new drywall or over drywall patches it is always a good idea to first use a primer – and besides, using a quality drywall primer is typically much less expensive per gallon than using multiple coats of a quality interior latex paint.
Sand Your Primer
I always use oil-based primer on woodwork and cabinets so that I can sand it down to a super smooth feel before beginning my finish painting. Use 220-grit paper or fine sanding sponges to sand everything down once the primer has dried enough that it generates dust when sanded.
Sand the Primer
Let the primer dry completely, then sand it down before painting. Use very fine 220-grit sandpaper, and apply light pressure to prevent gouging the primer. Remove the primer dust with a quick brush from the shop vacuum, followed by a light swipe of the tack cloth.
Dries to the touch in 30 minutes. Can be recoated or topcoated in one hour with latex or oil-based paint.
How do I get a smooth finish with oil based primer?
Apply a good oil-based primer and once that has dried, sand it with 120 or 150-grit paper until you feel a completely smooth surface. If you start with brush marks in the primer, then there is no way you'll get a smooth surface for the paint.
Made with ZINSSER's unique proprietary acrylic resins for exceptional flexibility and durability, Bulls Eye 1-2-3 has great hide and can be tinted towar d the colour of the topcoat to eliminate one coat of paint. It's a gr eat base coat for decorative finishes - can be used under or over ANY oil or latex paint.
Latex paints will not stick to oil based paints. The exception is that an oil based primer may accept any kind of top coat paint. For that reason, an oil based primer is recommended to be applied over any oil based top coat, then a water based paint may be used as a top coat.
Water-based paint does not require solvents of any kind, because the pigment carrier is water. If you choose to paint over alkyd or oil-based paint with water-based paint, you will have to remove the gloss before any new application. This is easily done with a fine-grit sandpaper.
CAN YOU USE OIL PAINT OVER WATER-BASED PAINT? Yes. In fact, this option works so much better than the opposite: painting with a water-based paint over an oil-based layer. This is quite common when you use primers to prepare a wall, cabinet doors, or trim for the final paint layer.
Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces†. Use under or over water-based or oil-based paints. Not recommended on flooring.
Oil-based primer is typically used for projects that require a tight seal. Water-based primer works well for indoor areas that are less likely to contact water. Oil-based paint off-gases more VOCs than water-based paint, making oil-based less idea for indoor use.
Oil-based primers are better than latex primers at sealing nail heads, covering knots in bare wood, and blocking tannin bleeding and other stains. They are also better for sealing bare window muntins that will be covered with oil-based window putty.
If you use any method other than sanding to remove the failed latex, you must then sand the stripped surface. The next step is application of a bonding primer; this is an absolute necessity before applying conventional latex paints over an alkyd finish.
Latex paint dries to the touch in one hour and cleans up with water. Alkyd paint dries to touch overnight and cleans up with solvent.
What is the difference between oil and alkyd paint?
Alkyd paints are the modern descendant of oil paints. Instead of pigment suspended in oil, alkyd paints are typically formed by an alkyd resin dissolved in a thinner.
Always prime when using water-based over oil-based paint.
Apply one to two coats of an oil-or water-based bonding primer and dry according to product directions. You'll know the surface is adequately primed when the former paint color, stains, and other surface imperfections are no longer visible.
Oil-based primers are ideal for interior and exterior unfinished or bare wood because they seal the porous surface of wood, enabling the coat of paint to better cover the surface. They stop tannins, released from woods, such as cedar or redwood, from bleeding through the surface of the paint.
