I'm a newbie here, but not a newbie to DIY. Somebody's gotta do it. I've spent 2 days reading and looking at all of your beautiful countertops and making notes. Now I'm down to trying to figure out what sealant to use, so would like to take a vote. It's the democratic way, right? I read a lot of you use the enviro-lite, but to some seems intimidating. Since this is my first time, not sure I want to be that intimidated.

Others I've read have used water-based poly, oil-based poly, Parks Super Glaze, and Varathane Diamond, so I guess what I'm trying to determine is which one.

There are so many of you that have done beautiful jobs, but used different sealers. Can we have a vote here please? I'm not "sponging". I'm using Rustoleum's stone spray stuff, if that helps. I'm using a tan undercoat layer first. One more question, does that need to be latex?


Thank you. And glad I found you guys.

I am guessing that you have already done your countertop, but I used a khaki green undercoat, then sprayed two coats of Rustoleum stone spray, and covered with Envirotex. I was dissapointed that I virtually lost the look of the stone spray after I covered with Envirotex, and I ended up with khaki countertops with subtle stone specks. It is almost too glossy and my husband says we are not doing that to any more of my countertops!

I think it would have been better to have used several coats of water based polycrylic rather than Envirotex. When I tried it on a piece of cardboard, it was just the way I wanted it, but bumpy from the stone spray, which I thought I could remedy with MANY coats of poly.

The Envirotex was not that hard to use, but it did seep through my tape and got into the sink. We used a razor blade to remove the tape and it's not as even around the sink as we would like, but it would not be nearly as noticable had we used a lighter undercoat.

First of all, Parks Super Glaze is like Envirotex. Second, I also am a newbie and just did my kitchen island. I sponged and used Famowood Glaze Coat from Lowes, also, like envirotex. I ran into problems with bubbles. Even though I torched the bubbles out, as it was curing, I ended up with bubbles all over the surface! So now have to sand and do another coat, or give it a satin finish.

The epoxies give a very nice shine, and are food safe. If I was going to choose a poly, I would choose Varathane water-based Diamond Gloss. I've heard the oil based yellows. Maybe you could find some pieces of wood to do test runs on, and finish one with epoxy, and one with poly. That way you can see first hand which one you like better. I wish I would have done that. I practiced on four t.v. trays and finished all with glaze coat.

Also, I've already noticed that finger prints show up very easily on the glaze coat because of the glaring shine. One consideration, I think an epoxy would cover the texture of the spray stone better than a poly.

Skanepa, when you put on the glaze, did you smooth it out very lightly with a foam brush? I had my hardwood floors done a few years ago and when they put the varnish on, they used a tool that was like a paint pad, it was wider however. I would think that would take out the bubbles although I have never done it. You are right the oil based varnish yellows something terrible. I would never recommend anyone do that.

Laniegirl, I used a wide plastic spreader to spread out the glaze. You are also supposed to use a handheld torch to get rid of the bubbles, which I did. It was smooth as glass, then when curing, the bubbles began to pop up all over, (not suddenly) and when I tried popping them with the torch, or by blowing on them, they left dimples, so I decided not to pop them anymore. I guess I should have torched over, and over, and over. I will watch it like a hawk the second time around.

Travis, go to the top of the page and click on the tab "find". Then type in "Painting Laminate Countertops". You will then have to scroll down until you see the title, "Painting Laminate Countertops". That is the thread that has the most info. on doing your countertops.

I kind of have the same type question. I have a beautiful medium sized vanity with nice trim detail that has a laminate top, rest is wood. It was an ugly yellow with gold trim so I wanted to re-paint for my 10 year old to put in her room.

So, after researching for almost a week, this is what I did. Please bare with me in my lengthy explanation.

Starting out with a smooth laminate vanity top already, I knew I had to do nothing to it except make sure it was clean so I put Glidden gripper on it which was white (gray was the only other available color). It went on nice and even, used a "Purdy" brush.

I let it dry 24 hours and I first tested the front removable piece of wood that I could screw off and I painted it with "Ace" Premium Enamel spray paint (deep purple).

It was so nice looking the next day, so I sprayed the vanity but I ran out and they did not have that color at the store anymore. So I continued with some left over paint of the same color but in a gallon can, but it was Behr Premium Satin Latex Interior, Exterior paint. Good for wood, etc. I let dry for 24 hours. Again turned out pretty nice but needed a 2nd coat and a nice glossy finish to add a nice final touch.

After letting that dry, I used an "Ace" Clear Enamel, but noticed the next day, some parts were shining like glass and others dull and grainy almost as if I painted a wood top with a natural grain. It was really noticeable from a distance, especially in the light. Plus, even though the gripper was evenly applied with a brush and I spray painted it evenly with the enamel, I really wanted the glassy look like some of the spots were but I ran out.

So I went back to Ace, told them what I did and asked for a good shiny, clear glossy, easy care finish that I could brush on. He handed me a pint of "Minwax" lacquer. I thought, "Great"! I just saw that online and researched it a bit so I thought I was good to go.

Not! I went home and OMG. I used sparingly but evenly, whew the fumes were unbearable, even though I opened the garage and wore a small mask. I did not want to use another spray can, that was horrible doing that so I used a brush and it showed the strokes so bad and dried to a milky dull finish. Not only that, but as I was painting, it stripped off some the paint to show the gripper so I had to re-paint those spots. It was difficult because I could not bare down like I wanted to because it removed some of the paint but I had to paint quickly because it dries so, so fast. I am also concerened...even after the proper waiting period that it might be hazardous to my daughter having it in her room.

I really was just looking to restore an old piece of furniture and work on a little project. But after further research, I see I would need to lacquer and sand, lacquer and sand and repeat too many times. Then seal then sand then buff, etc, etc. Whew! Ok, after that whole speech, I would like to know if I can just get some "Sierra Acrylic Enamel" and top it with that and be done with it to avoid more lacquer or starting over. I am only asking because I have the matching 6 drawer dresser to do also but do not want to go through what I went through. I really want these to turn out nice, but not costly or hazardous. Thank you. Signed, Not an expert. LOL.

3 days later, "The Expert" cost me $9.00 to answer incorrectly, after ruining it, he is now telling me to use MinWax Poly-Crylic. I have already bought the Enamel spray. What to do. What to do! And why did the lacquer bond to the wood part of the vanity after the steps of gripper, then latex but looked different on the laminate after gripper, latex? I mean, see how shiny the legs are. Now what to do with the rest. Sorry so lengthy. I am wore out, as I am sure you are from reading this.
