Direct answer: Textured and porous walls need extra prep: clean thoroughly, repair high spots, use the right primer/conditioner, and simplify details so the texture doesn’t fight your edges.
Quick takeaways
- Texture exaggerates wobble—make shapes bigger and cleaner.
- Primer/conditioner helps paint lay down evenly.
- Rollers can help fill texture; brushes are for edges.
- Test a small area first to confirm adhesion and sheen.
The big trend these days is to apply a vinyl printed sticker on a smooth office wall or glass. While I will not go into detail about the advantages and disadvantages to this process here, I will say that it is not very effective when a wall has even a small amount of texture. Wall texture is a big reason clients find use for my services.
To achieve a nice sharp edge on a textured wall is extremely challenging and time consuming. I employ a few techniques I have learned and will briefly describe them here.
The first is Frog tape. This special tape secrets a tiny amount of glue foam at the edges once it has been applied. This prevents paint from being sucked underneath gaps caused by the wall texture. It is an absolutely magical product that saves tremendous time and energy.
We recommend a 2-step system, the first being a permanent isolation coat, followed by GOLDEN MSA Varnish, a removable varnish.

- Repair chips and high points
- Prime/condition for porosity
- Block large shapes before detail
- Choose a finish suited to cleaning
FAQ
Can you paint fine detail on textured walls?
Yes, but it’s harder. Increase scale, simplify edges, and use the texture as part of the style instead of fighting it.
Why does the paint look patchy on raw walls?
Porous surfaces absorb unevenly. A primer/conditioner evens out absorption so the topcoat reads consistently.
