Glossy top coat 4 painted kitchen counter that's tough- waterprf ?

by Liona Shareing
I've painted my ugly old formica kitchen counters and how am having a problem with the clear top coat.
I washed it well before starting, then dry applied 2 coats of 123 primer, Next Rustoeum american accents copper metallic acrylic paint faux finished with craft greens/blues and sponged on more copper to blend.
next 2 coast of the rustoleam 3x thick polyurethane that I applied to my kitchen counters. I waited 24 hrs between each layer, then didn't use the counters at all for 4 days, then if I used them put a towel down to prevent water from getting on it for 10 days.
I love the way it turned out, but am sad at what has happened.
The area at my sink is bubbling up and when I put anything wet on my counters, it creates a white mark although it goes away. I initially used water based epoxy but it bubbled in places. I'm thinking it might be the metallic paint causing the problem since I did this in a marble look a year ago and there wasn't this issue?

    Look at Famowood clear epoxy. Check if it is heat resistant for around the cook top and ask customer service how to get it on the surfaces that are not flat. Other than that it may need an oilbase finish rather than water base.

    thanks for getting back to me I'll have a look at it, the area in the cooktop seem to be ok as I don't get them wet. I might have a problem getting oil based in California

    Polycrylic it's waterproof, I had painted the counters in my old house and covered in 7 coats of polycrylic. It's good to lightly sand and put a fresh coat on once per year afterwards for maintenance. 8 years after painting those counters my house was up for sale and I over heard a realtor tell a client that they were marble & had to disclose to them they they were in fact painted! So the more polycrylic the better.

      I know this is many years later but I am having a heck of a time with the polycrylic and bubbles! Any tips? I've tried the foam roller and those were the worst! I'm not over working it, put it on evenly and still get ripples too. I just sanded with 400 to 1200 grit and was just going to seal it with water but now debating another poly cost. Thanks!!

      thanks but I did all the steps and in it they say to dry any water that might get on the counters which I think means not to also leave anything damp on it.

      I use the polycrylic and it bubbles up when I spilled hydrogen peroxide on it. Regular 3% hydrogen peroxide. Ridiculous. Now I have to redo the whole counter.

    Could there be a water leak from behind the short vertical board? It seems to me that something is getting under the paint/finish on the counter from behind the short backsplash board. I'd remove the board and see what's going on.

    It's actually tile that was stuck on by the plumber using silicone caulk. I don't think it will come off without ruining the finish completely. What I think is happening is that water is splashing off the tile and running down the narrow area between the sink & tile pooling where the bubble is. Any suggestions for a completely waterproof clear top coat that won't haze when wet?

    Looks like your new paints have reacted with your former marble painting. I know how disappointing this must be after all your hard work! After years of painting with different types of paints, I've found that some paints are incompatible with each other and form that raised up look that you have at your sink. You may have to use a paint remover and then sand and completely clean off all your current paints, as well as the previous marble look paint you did a year ago. Then, on a clean surface, do your copper look all over again. I know it sounds like a lot of work, but I'll bet that this recent refinish is reacting with your previous marble paint.

      I used the zinsser oil-based primer and it was great.

    I just used the same Rustoleum 3X self leveling poly and it is terrible. It shows every brush mark and has these circles that look like water marks form while it is drying. I would not recommend this product at all!

    I blew up the pic of the sink area. The caulk job period does not look good. I see dark places at the bottom of the tile the plumber put on. Looks like mold. Why did the plumber put the tile there? I really wonder if the plumber did not add to the problem. Just because he is a plumber does not mean that he does perfect work and/or know what he is doing. The original wood underlayment is it plywood or that I think mdf/glued together saw dust. If you have a small leak into that stuff you will soon have a rotten mess. The caulking he used never really dries hard. It usually stays plyable. I would suggest to remove it as best you can and do a patch job on the paint or use decorative tiles cut to fit and go around all the counter tops for a punch. I am getting ready to paint my counter tops. Was going to replace them with senior moment the stuff you glue down that is rather heat resistant. Well had a big vet bill so I am going to have to paint them. I hope it works. I am a DIY person. Hope this helps
