It depends on the paint and composition. An oil based mastic paint used, for example, for waterproofing a basement is not porous, however an oil based wall and trim paint is. Check the manufacturer's data sheet to be sure.
Rust-Oleum chalkboard paint is not entirely non-porous; it can have a slightly porous surface once cured, allowing for chalk to adhere. However, it is designed to create a smooth and writable surface that mimics traditional chalkboards. To achieve a more non-porous finish, it's recommended to apply multiple coats and ensure proper curing.
Wood that has been painted is generally not recyclable in standard wood recycling programs. The paint can contain chemicals that may contaminate the recycling process. However, some facilities may accept painted wood if the paint is water-based and non-toxic. It's best to check with local recycling guidelines to determine the proper disposal method for painted wood.
No, most plastics are smooth and non-porous. For wood glue to work well it needs to soak into the materials that it's gluing. It can not do this with plastic, so will seem to stick at first, but will come loose when fully cured.
If water droplets penetrate within 3 minutes or less it is considered porous, if water droplets remain on top it is considered non porous..
Spray paint does not adhere well to waxed paper because the wax coating creates a non-porous surface that repels paint. This results in the paint likely beading up and not sticking properly, leading to smudging or running. For better adhesion, it's advisable to use a different type of paper or surface that is designed for painting.
because it is non-porous.
There are two types porous and non porous. You can also seel porous concrete to make it non porous.

No but you can make them non-porous by putting a satin acrylic finish on them.

The paint is not sticking to plastic ornaments because plastic is a non-porous surface, which makes it difficult for the paint to adhere to it properly.
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
I think it is because metals are non-porous, with more dense and compacted molecules compared with water, wood or other porous materials.

Plywood is generally considered non-porous because it is made from layers of wood veneers glued together, which creates a solid, dense structure. However, the surface can absorb moisture if not properly sealed or finished. The degree of porosity can also depend on the type of wood used and the specific manufacturing process. Overall, while plywood may allow some moisture penetration, it is not classified as a porous material like untreated wood.
To make concrete non-porous, you can add a waterproofing admixture during the mixing process. This helps to reduce the absorption of water into the concrete, making it less porous and more resistant to water penetration. Additionally, you can seal the surface of the concrete with a waterproof sealer to further enhance its non-porous properties.
