## Questions & Answers

**Q: would this make my paper crafts stiff, if I used it on coat them?**
A: I had never used this on paper before.  I have used it to repair the surface of castings.  In response to your question I took a piece of origami and sprayed it.  The spray did not do any damage to the paper.  The paper was left with a mild sheen.  One coat did not make it stiff.  Maybe more coats would make it stiffer. It did look like the paper had a protective coating.

**Q: Will this harden and protect a sand dollar -- basically keep the sand dollar from cracking and breaking?**
A: No, this isn't what you're looking for. This is a sealant for resin, not other products. However, you might consider either 1: brushing or dipping the sand dollar in resin, or 2: Triple Thick Sealer. I think resin will probably work best for you--check out the website Resin Obsession for more info. (Not affiliated, just love 'em.)

**Q: can it be used to coat baked polymer clay coasters and can it be used indoors?.  How strong are the fumes?**
A: It can be used to coat baked polymer clay pieces, but you could end up getting a "cloudy" look if there's any humidity in the air. This thing has pretty strong fumes and I definitely wouldn't recommend it indoors. The bottle says to use in a well-ventilated area, and I'm assuming that means "under a venting hood" if you're planning on doing it indoors.

**Q: What is this product mainly used for and do I need to buy it?**
A: No you don't "need" to buy it. It's used to seal off resin pieces to protect them from finger prints, fill in minor flaws and such. It's handy but not mandatory.

### ⭐⭐⭐⭐⭐ RESIN LIFESAVER!
*by S***M on July 8, 2012*

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!

### ⭐⭐⭐⭐⭐ It does work and goes on clear if you do it right
*by C***Y on July 11, 2020*

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.

### ⭐⭐⭐⭐ Works well after trial and error
*by C***J on December 6, 2012*

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.
