Painted wall going up the staircase. Looking up you can see where roller stops and starts. Does not blend in. Walls are rough, such as swirl marks, lumps with air holes. It is hard to decribe. Problem is only on a couple of walls and certain places on ceilings.

Used Kilzs. Valspar paint. Semi smooth surface roller. (not the top brand)

What has happened? Thanks

Hello Marie:
I find that folks are shorting the wall on paint when lapmarks, swirls and such are a problem.
You may want to use another coat and each time you make a strip with the roller just use light pressure and lap back over the last strip.

also don't just go up and down in a regular pattern, go all different directions so you don't have lines.

The term for the technique is called "Keeping a wet edge". It means you never apply new wet paint over new dry, or almost dry paint. That includes cutting in. When you cut in you should have someone immediately behind you rolling over the cut-in wet paint. Also, no excessive pressure and don't skimp and try and stretch the paint. Lastly, use a top quality paint. Valspar is now, I think, a store brand for the big blue store. The name came from a top quality floor finish if memory serves me.

Try recoating with Benjamin Moore and see how you do.

I find a brush used in various directions works marvels on an uneven surface, far easier to manage than a roller
