## Description

Solarez Polyester Grain Sealer - desertcart.com

Review: Best Grain Filler I've Used - It took me a while to figure this stuff out, I have to admit. It never seemed to stick to the wood and came off when I sanded it at first. Glad I didn't give up on it. The trick (for me at least) is to put an ultra thin coat on the wood first. As thin as you can get.( I used a super fine brush). Take it outside and let it cure for like 5 minutes. Then bring it back in and after a few minutes rest,, take it outside again for a few more. Next, I added a thicker coat, repeated the process and left it for a couple of hours. When I came back and sanded it, it turned out perfect. It powders up beautifully and leaves the absolute smoothest surface for painting. It's pretty unreal, actually. I will never use another grain filler. BTW, I build electric guitars and for opaque finishes, it's just about the best thing there is.
Review: Works Perfectly - I have used several grain fillers and this is by far the best. Sets up really quickly when exposed to sunlight. Takes very little to complete my projects. Use sparingly!! I work mostly with walnut and mahogany and have always been frustrated with other grain fillers and clear coats. Before using this product, it would take days and several coats of spraying and sanding to get the results I got with this product in one coat. I use a small sponge "brush" to apply a very, very thin coat. You will know if it is too thick because it will bubble up. Allow the brush strokes to settle for a minute or so and then expose to sunlight for 2-3 min. After the entire project is covered, I use 0000 steel wool to sand the entire product and then coat with an aerosol top coat. Comes out perfect! No grain dimples and the finish is like glass. If you want a thicker coat for heavily used wood items continue with the 0000 steel wool and recoat with aerosol urethane until the desired thickness is achieved. Cuts project time by more than half. It is expensive, but worth every penny because it works and only a small amount is needed to fill the grain. Use Sparingly!!!

## Questions & Answers

**Q: Can i use a uv flashlight to cure the filler?  i am doing a project where we can't get sunlight.**
A: You certainly can but it must be UV 385nm. That is NOT a 365nm or a 395nm or a 405nm. LED lights put out a very narrow range. If you get a 395nm torch, it will put out 390nm - 400nm, NONE in 385nm. Likewise if you get a 365nm torch, it will put out 360nm - 370nm, NONE in the 385nm region. 
The Solarez High-Output UV flashlight puts out 385nm, that's from 380nm - - 390nm and is perfect for curing Solarez resin. It has only a 3" diameter beam so you only do small projects

**Q: Can you paint over solarez grain filler with latex acrylic paint**
A: certainly, you can. Be sure to flat-sand the sealed wood to 150 grit before painting

**Q: Would the grain disappear  if a cabinet door is painted with a solid semigloss latex paint? I want the cabinet not to look that is made of wood**
A: If the door is bare wood, i.e., un-painted or stripped, then the filler applied followed by sanding ... then yes. But I do not believe it would be effective over a stained/varnished surface.

**Q: Would you be able to apply a 2K (catalyzed) polyurethane finish over this?**
A: Once dried yes but not sure I would do it this way. I prefer an epoxy base coat compared to solarez grain filler.

### ⭐⭐⭐ Good—not great. Wear a mask.
*by A***R on September 22, 2020*

So the manufacturer says it is “virtually zero odor” which is like me saying getting kicked in the balls causes virtually no pain. This stuff has a VERY strong odor and I would highly recommend wearing a ventilator. My entire garage stinks from a small test application. Secondly, I’ve been testing in SoCal on a sunny day and it is taking longer than 10 minutes to cure. Pros: Once it finally did cure—about 20 minutes—it sands very easily and I was able to get a nice smooth surface. Overall, Solarez is good, but not great. It’s a little finicky to work with and doesn’t cure anywhere near as fast as claimed, but the end result was really good.
