Painting Question

[CaptainYooh]

Hey CP'ers:

I had to do a few paint touch-ups on a large wall, which I didn't want to re-paint whole. Got the paint colour matched up nicely. Eggshell finish. But I guess the old paint flattened more than the new paint over time, so the touch-ups are flashing. You can see them shining at some light angles. I tried sanding them lightly with a sanding block, but that didn't do much.

Any helpful hints on how to reduce flashing and make them blend in more would be very much appreciated.

Maybe it was flat and not eggshell paint?

[CaptainYooh]

It was definitely eggshell (I kept the empty old can of it for future reference).

Ok, maybe try a bit of flat then anyway? I find that flat doesn't reflect or shine at all, while eggshell might. Home depot sells these $5 samplers, worth a shot.

You probably have to paint the whole wall if you want it to match properly. It's a pain but I don't know any way around it.

I have always found a patch of paint shows even if from the same can just a few days later. If you don’t do the whole wall the edges are there.

The best I’ve managed is feathering out the edges with a small sponge brush that’s almost dry. Not going much beyond the patch (no point making it bigger) just breaking up the edges a bit. Maybe it’s in my head but it seems a bit better.

Part of it is the application, if you rolled the walls with a roller, the finish is going to be different than if you touch up with a foam brush.

I often find the wall sometimes fades over time so when you go to touch up it’s no longer the same color. Whole wall is my go to elixir here

This is a stairwell wall. Tape-masking everything off (baseboards, railing, metal spindles etc.) is not a DIY job (for me) and hiring a professional painter is not in the cards right now, unfortunately.

I’d paint the whole thing with a roller but wouldn’t bother cutting in or taping. I doubt you’ll notice near the edges, but based on your description I’m not sure how you’re going to patch it in a way you’ll be satisfied with.

You could try, and then fall back onto my strategy as step 2 if it doesn’t work.

Eggshell sheen will reduce slightly as the paint cures from my experience. Latex paint doesn’t fully cure for about 4 weeks. So you can try waiting it out which is easier that the other options. Painting the whole wall is the only sure fix, but being a difficult stairwell you obviously would like to avoid that. Unfortunately the sharp angle you see a stairwell wall is the exact one that shows flashing differences.

Probably, the most sensible thing to do now.

Did you use a chip/piece from the existing paint? I find that’s more accurate then the original formula. Cloverdale does a great match, better then hone depot.

It's the sheen, not colour. Touch-up spots are practically invisible when I look at them straight. But they flash - show a glossy shine at certain angles, because old paint lost most of its sheen.

[CaptainYooh]

Has anyone here used paint deglossers on latex painted surfaces?

[Engine09]

Good info in here but way too many words for a simple issue. Too many variables, tint, old faded wall, different type of roller, etc.

Cut and roll the entire wall and be done with it.

[Fuzz]

You could try a tsp solution on the new paint to knock the gloss off.

It's definitely possible to paint a patch and make it look good, but getting a good colour match is harder than you'd think and it wouldn't surprise me if its off just enough to be noticeable, I think odds are it just doesn't match well enough to not show and you need to paint the whole thing.

But I would say there is a possibility the texture of the patch is different from the drywall, to fix this you need to sand/paint, sand/paint, sand paint, until you are seeing the paint texture and not the mud texture. the same colour with different textures will appear to be a different colour.

You also need to make sure you are putting enough paint on the patch, and feathering it out over top of the original paint. if your paint is too the texturing will be a problem.

I do this a lot being the perpetual parent of angry teenage boys, what you need to do is gradually feather off the finish from the patch out into the old paintwork, so fully load your brush or roller over the patch but allow the paint to run out so as to gradually go from new paint to old

Perhaps the finests of steel wool to burnish it?
