Question 1

How much am I suppose to be sanding? I took some 220 grit and then 400. The 400 felt like it was sliding on glass. Also I have an etching design on the bottom of the tub that is lots of circles. Is that a problem?

Accepted Answer

We used120 grit first to the whole area looked dull then we went over the whole are with 400 grit to make sure it was completly smooth before treatment.the bottom was rough when we started after the sanding and paint it was completely smooth .

Question 2

what kind brush I have to use it?

Accepted Answer

I used Black China bristle, the product is like an oil based paint, a small foam roller would be better because you won't get brush strokes.  The epoxy product is harder to work with, don't over brush if you do it with a brush.  And reverse your stoke on the second application.  Good luck, ventilate the room really well and wear a mask even though the directions don't require it.

Question 3

why would the second coat bubble up and peal off. How do you repair the peeled off sections. Tried to recoat and bubbled up and peeled again.

Accepted Answer

Same problem. I believe the issue with me is that the bathroom temp was around 90. For this paint to dry properly the label says 65 - 90 degrees  and less than 80% humidity. I turned my A/C down and monitored the temp in the bathroom. It was about 78 and no bubbling occurred, so I assume the temp was the problem. I assume with this type of paint, temperature is very important. Unless your a professional painting in really cold weather, who really pays attention to that aspect of the process? Not me.

Question 4

What is a good roller to use with this product.

Accepted Answer

The box recommends a roller with a certain nap and to wrap the roller in painters tape before you start to remove any loose fibers. I used a 4" Purdy brand roller of the appropriate nap (purple-colored as recommend by Menard's paint staff). I used a new one for my 2nd coat. My rollers did not fall apart or lose any fibers, but I wonder if I would have had better coverage if I switched it partway through (as suggested in another question/answer). Make sure you get a good brush--it's annoying if the bristles come off in your paint surface.
