I did my master bath vanity top with this product several months ago. The product is great, and the surface still looks just like it did when I finished it. It is a tremendous improvement over the previous laminate that came with the house. Another reviewer mentioned problems with the topcoat going cloudy and bubbling up from standing water. I have not had that experience at all. I don't have constant water on my vanity, but I generally don't bother to dry up day to day splashes. I was thorough when applying silicone caulk around the edges of my sink, so no water is getting underneath the topcoat. Getting water underneath the top coat will definitely ruin the finish. (I am not implying that the other reviewer failed to caulk properly; it could have been a a bad batch of topcoat.)
I do have some minor quibbles with the finished appearance, but they are due to my errors during application. Now that I have made those mistakes, hopefully I can do a great job next time.
10 Things I've Learned:
1. Prepare surfaces exactly according to directions. Scrape off every trace of old cracked caulk (and smoothly apply new paint-able caulk), or you'll have small ridges and creases where the backsplash and vanity meet.
2. If you're applying over laminate that has black seams along the edges of the backsplash or between sections, sand and fill until smooth. If you leave any cracks or ridges, they will show through.
3. Be careful to get your painting tape on straight and exactly where you want it. Use a hard straight edge (like the edge of a putty knife) to press the tape down firmly to reduce paint getting under it. Like another reviewer said, you will want to have some touch-up wall paint, just in case.
4. Remove the sink/stove before painting, if feasible. It's tricky to get the mineral colors to look exactly right all the way up to the edges of the sink/stove. If you paint with the sink/stove in place, be very careful to apply the mineral colors consistently all the way into the crease. Otherwise, you'll have a black rim around the sink where the primer shows through.
5. If you have a round sink, resist the impulse to work in a circle around the sink...you'll change the pattern of the mineral colors, causing a subtle halo effect around the sink.
6. Another reviewer suggested using a paintbrush to apply mineral colors to the sponge, rather than dipping the sponge into the paint. I think that is a terrific idea, especially when doing the backsplash and front edge. The mineral colors are thin and run easily on vertical surfaces if applied too heavily.
7. Practice, practice, practice the mineral colors application until you get colors and textures that look realistic to you. Black posterboard is cheap and a few minutes of practice could save you a lot of time and frustration fixing your counter later. You can also try out a few different shades and then carry them into the room and see how the colors will really look before start painting. You may decide you want to go with a darker or lighter color than you first thought.
8. If you do mess up the mineral colors, as long as you haven't applied the topcoat yet, let them dry and paint over them again. If you have runs/drips, or if you want some of the primer black to show through in the finished product, sand the dried mineral colors before repainting. Be careful not to sand all the way through the primer or you'll have to start over.
9. Be very careful with the topcoat application on vertical surfaces; it runs easily. (If you get runs, you can sand the topcoat and re-apply.)
10. Remove the painter's tape exactly when directed. Also, it is crucial to carefully score the tape with a sharp utility knife before removing it. Otherwise you risk peeling off all your work along with the tape.
Not a tip, but a preference: I really liked the smoother finish from doing the optional sanding step after the minerals coat and after the first topcoat. In my opinion, it's worth the time. Just be careful not to sand off too much color or you'll get a lot of the primer black showing through.
This kit is pretty much infinitely customizable. The instructions that come with the paint tell you how to make "veins." You can use water-based acrylic paint along with the mineral colors, so the color possibilities are limited by your imagination. One person who reviewed a different color kit suggested flicking a toothbrush to apply tiny spatters of silver to emulate small quartz crystals. I am planning to do my kitchen counters next and I will try that on my practice boards - if it looks good I will use that technique on my counters. You could use gold to emulate mica flakes, or a shade of green, brown, or bronze for an accent.
You can also order single cans of any mineral color direct from the manufacturer. (Amazon sells most of the mineral colors, and Amazon is cheaper to get a single can when you consider shipping costs, but as of the date of this review Amazon does not sell all of the colors.) I recommend going to the manufacturer's website in any case for more pictures and ideas. When I was planning my bathroom counter, I was torn between the chocolate brown kit, which I thought would be too dark, and the sand kit, which I thought would be too light. I ordered the sand kit plus a can of the chocolate brown paint. I used small amounts of the chocolate brown to get a slightly darker color and more "depth." When I have the time, I plan to redo that vanity to fix the mistakes I made the first time, but I will probably keep the colors the same.
