Question 1

Can I just paint over hairline cracks in plaster?

Accepted Answer

•

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board.

Question 5

Can textured walls be smoothed?

Accepted Answer

•

Certain drywall textures, like sand and sometimes popcorn, can be smoothed by applying skim coats, sanding the walls, or chipping away the texture. However, it’s worth considering removing the texture and starting with a blank canvas. Smoothing textured walls requires a lot of sandpaper and elbow grease and can take longer than just outright removing the texture.
