Default Need advice - pre-primed panels

We did a job for a basement waterproofing company that refinished a basement with pre-primed panels that had vertical strings on them (similar to sting on mesh drywall tape). The panels were a bitch to paint. The paint dried instantly and was a pain to roll. We started with an 18" roller, but that didn't work, neither did a 9". We used a 3" roller for the entire basement - SW Harmony Flat (watered down significantly to it would spread) - 5 gallons, one coat for about 600 sf. We applied the first coat and returned several weeks later to apply a final coat full strength. At that time we noticed the cuts were darker than the roll. Two coats later the cut lines were still visible. We rolled as tight to the ceilings and base as possible, but it appears the 1st coat cut is still visible. We were hoping it would dry and cure evenly but got a call today that the homeowner is unahppy with the work and would like us to fix it. In my opinion the panels should be sprayed or rolled before installation. The paint dried so fast and had to be applied heavy it changed the surface of the substrate. I can't imagine another coat will fix it at this point. We don't know what to do. But do know never to work with these panels again.

Do you have any pic's or a brand of the panels? What are they made of? Why Cashmere? Very thick paint to work with.

what color paint is it? is it a dark base?

Sounds like u need to mask off all the edges and spray, or, use a whiz roller for the edges first and then roll. Or it could just be an application problem from the start (too thick brushing for cutting in). Where i need to extend open time on paint for better finishes, I'll use flotrol. I've had good results with it, I know some on here don't like it.

Pre primed stuff isnt. Sounds like it needed to be primed/sealed. At this point, put a sealer down...then paint as normal.

What do you mean by darker? Are you talking color? or is it probably a heavier cut than roll?If so just roll without cut.Or is it picture framing?? Need pics for a cure!!

Perhaps you needed to thin your paint more for the cutting. Could have saved yourself a huge headache by re priming the pre prime.

The GC supplied materials, I am not familiar with SW.

Boxing was not an issue, it's not your typical color banding.

For the final cut we rolled as tight to the trim and ceiling as possible. Another coat will most likely produce the same results.

"too thick brushing for cutting in" has something to do with it. But it was the only way to apply paint to the substrate. I had to brush up and down in small increments.

Priming/sealing sounds like a good next step. I'll experiment on one wall and take some pictures.

Thank you.
