Why am I getting a texturewhile priming with a foam roller?

looks like you are pressing too hard. or did you clean the doors well before priming? If there is grease on the wood that happens.

I have painted cabinets quite a few times. I have had lines where the roller ends from pushing too hard, but I have never seen this, unless the paint dried on the roller, because it wasn't washed out thoroughly. I've even used $ store rollers with no problems. You used High Density foam?

Other than what Dee said, the only other thing I can think of, is that you kept rolling over wet paint. Is it an oil based/alkyd paint? I painted my dishwasher with a s/s look paint, and I got texture, because I kept rolling back and forth, instead of letting it dry thoroughly like the instructions said. I don't do that anymore. I try to be patient...which is hard but worth it.

It's possible there wasn't enough paint on the roller. That would leave dry spots and an uneven, patterned surface. When there's enough paint, as the roller passes over an area, the paint left behind flows together and creates a level surface. Experiment!

Could be residue from the deglosser ( I always lightly sand and advise it), not enough paint on the roller or a dry roller, Rolling over the painted surface to many times while wet (pulling the paint off).

I like to brush the paint after using a foam roller, it seems to dry smoother if there is enough paint on the wood. Sometimes it takes two coats too.

I would not use a foam roller on cabinets...invest in a good quality slanted brush by Purdy....best best brushes for smooth finishes, especially on cabinets, doors or woodwork like baseboards window frames, etc...Home Depot has them in all sizes, I always use the slanted brushes in different widths for various size pieces you are painting. Believe me they work beautifully!

there are grades of rollers just as there are for paint brushes. If you are using a foam roller on cabinet doors or interior doors you want to get the best quality. Also I'm wondering if you used primer first. I would prime then sand to smooth and then use a best quality roller
