Do I have water-based or oil-based paint in my house? The test to determine whether your paint is oil-based or water-based is pretty easy. Simply put some methylated spirits on a rag and wipe at a small section of your wall. If the cloth is stained with the wall colour, it is water-based.
Get some denatured alcohol, not rubbing, on a rag and rub the surface. If the paint melts, it's water based. If it just cleans the surface, it's most likely an oil.
A quick test you can do is to use DIGGERS Methylated Spirits and a clean rag. Put some of the methylated spirits on the rag and rub a small spot of the paint surface. If the paint comes off, it is water-based, but if the paint stays on and you get a shiny surface it is oil-based.
It's possible to lay a water-based color over an old oil-based paint, but only if you do the proper prep. We recommend sanding the sheen off your oil-based surface, then applying an oil-based primer to serve as a bridge or buffer between the old paint and the new.

One way to tell is to perform the “rag test” by using a clean white rag and a small amount of paint thinner or mineral spirits. The rag test can help you to tell if the paint is oil-based or water-based.
We all know that oil and water don't mix – they're 'immiscible' in scientific terms – and this is the same when covering an oil base coat with a layer of water-based paint. The poor adhesion leads to the painted surface flaking.
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.
When covering oil-based paint with latex or water-based paint, you cannot paint directly over it. You must sand off the glossy finish, wash the surface with TSP, and prime it before painting it. This will provide a longer-lasting paint job and prevent the paint from peeling.
Hold the painting at an angle and look at the paint's texture on the canvas. If it's highly textured and looks very layered, the painting is likely an oil painting. Acrylic paint dries smooth and somewhat rubbery-looking (unless an additive has been used to give the paint a thicker texture).
Get a clean rag and put some metho on the edge of the rag. Rub it against a section of the paint. If the paint comes off, it is water-based paint. If it doesn't come off and just becomes very shiny, it's an oil-based paint.
If you put latex paint over oil, you'll end up with that fruit roll-up look all over your house because they just can't adhere.
Oil-Based Paints: Acetone is highly effective in removing oil-based paints from various surfaces, such as wood, metal, and plastics. Enamels and Varnishes: It is also useful for stripping enamels and varnishes, which often share a similar composition to oil-based paints.
We recommend KILZ KLEAR® Clear Sealer & Bonding Primer – a high performance fast-drying, multi-surface clear primer developed to seal highly porous surfaces inside and outside your home. It is also recommended for use when painting the same topcoat paint color on top of an existing paint coat.

For example, you should always use an oil-based primer when painting over enamel. This will help the paint adhere to the surface better and will ensure that the final product looks good. In addition, it's important to make sure that the surface is clean and free of any dust or dirt before you start painting.
When using a water-based product over an oil-based product, such as water-based High Performance Topcoat over oil-based Gel Stain, If the oil finish was applied over raw wood, wait 24 hours between the two products. If the oil finish was applied over an existing finish, wait 72 hours between the two products.
Finally, rub a cotton ball soaked with rubbing alcohol over the area. If the paint comes off, you have latex-based paint. If it does not, you have oil-based.
Step 1: Put a little bit of rubbing alcohol or denatured alcohol on a paper towel, cotton ball, rag, etc. Step 2: Rub across the painted surface for a few seconds. Step 3: If some of the paint starts to rub off, it is NOT oil-based. If none of the paint comes off, it IS oil-based.
Broadly, acetone is an effective paint stripper, even after the paint has dried. Acetone will strip and/or dissolve other things, as well. It can remove super glue, for example, but use caution depending on what the super glue is on — acetone can easily damage varnished wood.
