Environmental Technology Castin’ Craft Resin Spray Crystal Clear Gloss Finish/Sealer (5.25 oz) Multipurpose Top Coat & Sealant for Polyester Casting, Polymer Clay, Paint, Woodworking & Cured Pieces

This resin spray has saved so many of my pieces that would have otherwise ended up in the trash.Some of my resin molds have slight scratches and imperfections that obviously show up on the piece after demolding. In this case I sand the piece under water with a 1500 grit wet/dry sandpaper, let it dry and then spray it with Castin' Craft Resin Spray. On pieces that have sharp edges I start out using a coarser sandpaper usually 400 grit and gradually increase to a 1500 grit.You would think that after sanding there would be no way in the world it could ever have a beautiful crystal clear shine and such a smooth feel. If used properly, it certainly will with this resin spray! The resin piece you are going to spray needs to be free of any little lumps, bumps, hairs and dust. If not, you will not get the shine you want and the spray will not settle properly.I would suggest trying the spray out for the first time on something you don't care too much about. If you spray too little, it will look splotchy. If you spray too much it will drip. Don't worry if you mess up, practice makes perfect! If still wet and I am not happy with how I sprayed or if I see a a piece of dust on it, wearing gloves, I squirt Dawn dish soap on the piece under water and wipe the spray off with paper towels and then spray again, of course you could always wait for the resin spray to dry, sand and respray, too!The spray works great in other ways as well. It you have a piece that still seems tacky the resin spray will fix that. It is also good for sealing your inclusions before putting them in resin. I love, love, love this resin spray. Happy crafting!

This product is amazing. We’ve been working on an epoxy bar top for weeks now. Our first pour had some issues and then this last pour 98% of the table hardened. 2 little spots were tacky. With fear the table was ruined or we would have to pour yet again we turned to other options we came across in blog posts. The reviews of this spray made me very hesitant. BUT after reading reviews and seeing many recommendations of people saying to brush the spray on, I did just that. I can see why the spray would be cloudy if you did not do this. The directions even state to hold the can 14” away from your project. If you spray thick, it would turn your piece cloudy. Brushing the spray on gives you more control of the thickness. We did have to do two separate thin coats, 2 hours apart, to completely take away the tackiness. But the spray worked. I am so thankful our project was not ruined! 10/10 would recommend for a quick fix on a epoxy project where slight tackiness is your issue.

This resin spray is finicky, but works well under the right conditions. Like others have said, the temperature should be over 70 degrees and the humidity low. (I managed to catch the last 70+ degree day of the year in New England!)I had poured a resin table top on a salvaged rusty metal cart that I was making into a coffee table. I had to sand it down to get rid of some defects, leaving the surface cloudy with little scratches. Since this was my first time working with resin, I had made a small test piece, which was very helpful throughout the process. The directions on the can said several lights coats of resin spray were better than heavy ones. I tried this on the test piece, but while the small scratches from the sanding got filled in, the surface was still a little cloudy with a pebbly, matte finish. Then I tried a thick coat, which ended up achieving a glossy finish, making the resin crystal clear again. The thick coat thoroughly wet the surface, drying glossy, instead of misty. (This worked for me because it was a flat surface, but it would drip otherwise.)I repeated the several thin coats, then a very thick one on the actual piece and it came out very well. I can now see through the 3/8" resin to the cool rust patterns that I wanted to highlight. I also used the spray on the rest of the cart to seal the surface. In the end, I'm very happy with how the resin spray worked on my coffee table, but it did take some trial and error to get there.

I'm still new to resin casting. I have found that, while it sounds simple, it's not as easy as you would think to get a perfect result. Ambient temperature and humidity, the shape of your mixing containers and mold, the kind of material you embed in the resin, curing time, number of layers applied - all these factors and more come into play.I found that this product goes a long way toward ensuring good results. 1) it significantly decreases (if not totally eliminates) the stickiness you sometimes get on the final product 2) it smooths/improves the surface appearance of the resin product.

I have not had problems with this spray, though I aim to use it all in one setting. I noticed that when I used the resin spray a second time to coat some tile coasters, I didn't see the gloss that I was first pleased with after I had just opened the spray can. If your focus is high gloss, the spray may not be the best option, but if you want something that is somewhat waterproof that preserves projects such as art and woodwork, the spray may be worth trying. I've found it especially useful when coating paper craft projects including origami and paper beads. I haven't experienced issues such as tackiness and the spray wearing off when applying heat to my projects (coasters, primarily). It's useful to apply the resin spray in areas with little humidity and decent ventilation. I didn't find the fumes as strong as Krylon or even the Mod Podge Acrylic Sealer Spray, although as always, you want to be safe. Take precautions, and shake well.
