SW Cashmere Paint - Peeling off walls at trim...
 
I removed a chair rail and wainscot in my mudroom. I sanded all the walls in my mud room with 80 grit, then used drywall mud to cover all the areas where there were divots in the walls from the boards and nails. I then used a block hand sander and 220 grit to smooth out the walls. Next I used a microfiber cloth, slightly damp to wipe down the walls and then went over it again with a clean dry microfiber cloth. I then used a tinted Behr Premium Primer to cover all the walls and painted it twice. Finally I painted 2 coats of Cashmere by Sherwin Williams. When I took off the blue tape at the trim, it peeled in certain areas, so I started using a xacto blade to cut the tape of at a sharp edge. I was in a house that was air conditioned at about 72, however it was humid outside, but fine inside. And after I painted the 2 primer coat, I had to wait about 2 weeks before I could finish and do the 2 final coats and I left the tape on. Also, I used a smooth nap roller, so there is hardly any texture on the walls.

SO my question is... I need to fix the few spots where it peeled all by the trim (no larger then 1 in x 2 in) and I also need to paint the trim, but I am terrified to tape off the walls, as I am sure that when I pull the tape off, it will take the paint with it. Is it possible to sand the spot area without it looking like junk? Am I doomed to re-do all the walls? Can I add some sort of caulk at the trim to help? HELP!!

Here's what you do. Make sure you remove all the tape from the trim. Then fix where the paint has peeled by lightly sanding the peeled areas. You are trying to feather out the ridge between the paint that has peeled vs the paint that hasn't. Once you do that spot prime if you are down to Sheetrock I'd not the touch up these areas with the cashmere paint. Let this cure for about 3 weeks to be safe then use 1" blue masking tape and mask the walls from the trim and repaint your trim using either pro classic or solo in semigloss from SW.

What happened... Blue tape has a low tack (not very sticky) when compared to white masking tape. It does however get stickier the longer it stays on or surface or exposed to sunlight, running this risk of peeling paint when iris removed. Most on the market will say up to 7 days or 14 days for safe removal. All you did was allow the tape to stay on the surface for too long. Plus humidity and the amount of paint you have on the surface have led to longer dry times and cure times.
Also try mix brands of paint on your projects. If you have paint problems a manufacturer cannot stand behind a product that they do not make.

I hope this helps

Forget the blasted tape altogether for painting the trim. Get a GOOD brush and use a steady hand and take you're time.You put tape on those walls and I can almost guarantee you it is going to pull the paint off.
The problem from the get go was most likely the poor choice in primer.

Thanks... i like the feathering idea... i'll try that. I wish I had a steady hand to try with out the tape.

I was aware of the primer needing to be the same company, it make sense.

Have either of you used a caulk to make the edges of the paint and trim look "tight". I know you are pros... but curious.

Cpcphil - You said that I should NOT go back over the sheetrock with Cashmere? I would tend to wnat to prime with my same primer and final coat with the same can of Cashmere ... please advise if I mis-read.

Thanks again!

Sorry bout that. Yes I would touch up with cashmere but I would prime if you are down to bare sheetrock. I should not rely on autocorrect function.
