Uneven spraying causes these problems. Spray thinner coats.

So after you spray and after they dry are you saying bake in the oven at 200 for 20 minutes?

I wish I could find a video of sealers that aren't sprays. I can't use a spray because of the sides of my projects.

When doing these tests you can not compare varnishes if you don’t follow the directions on the label. The ones you heat treated that did not call for heat treatment probably broke down. Depending on the chemicals used in the product, it could have been dangerous for you as well! You should redo this “experiment” following the directions of the product to the letter.

Wondering, are they waterproof, ie sweating beverage glass.

I use karmar spray sealer first (3 coats) let dry between each coat. Then VHT same amount of coats. Bake at 250 for 20 - 30 minutes my tiles did not yellow at that temperature.

I think it's fabulous!

and we are here waiting. for the results thaaaaa???

Looks great. It's not obvious how spinning the tiles changes anything. It looks like the blowing is what's creating the design?

The huge plus of Diamond Finish is you can even cut and buff it to get it lookin like glass

Thank you for doing these. Looking for future tests especially since that winning Diamond coat is so expensive.

Thanks for sharing this video! I made some coasters with decoupage technique. I sealed the surface with Mod Podge for 4-5 times. After one week, I used Dupli-Color Varnish and let the tiles to cure for a week. Then when I put a very hot mug on the tile, it didn't stick but there was a deep circle. Could you please tell me what the problem was?

Do you apply top coat sealant first before you apply the heat resistant clear spray?

I’ve had good success with the Dupli Color one you tried. I sprayed 3-4 coats with 30 minutes in between then set the tile out in 85-90 degree sun to cure for 4 hours. Next morning I did the hot coffee test with no sticking! It was a darker tile so I saw no “yellowing,” there were some white parts on my design that do not appear yellow.

Have you figured out the best clear coat?

This is so informative, and your coasters are so pretty!

Beautiful! I would love to see what you do to the back.

Put a dowel in the hole

i need help w painting i bought. went to put in frame and it wrinkles cause not stretched

I tested the diamond sealer. I sprayed my tile with 5 coats, every half an hour inside so the temperature was about 70 degrees with little humidity. I let it cure for 3 days. I tested with a 12 oz mug of water heated to 180 degrees. Let the mug sit on the tile for 10 minutes. It stuck and left a ring. Not sure what I did wrong. Would you please give me some advise? Thank you.

Thank you so much! I’m new to coaster making. Def sub to you’re page!!!!!

how do you heat treat the coasters after you use VHT enamel engine spray? do you have to use a oven? or can you just spray them? ur use something else?

That's not how to varnish, it's not done the way Abstract Anneliese did the brush strokes, go straight across the canvas, not multiple directions and definitely NOT when it starts to get tacky. Then when first coat is dry turn the canvas so the next coat goes in another direction. Over brushing like she did will make is go cloudy, cause lumpy bits because it was clearly too tacky to be brushing it.

0:53 that one when I make a cup it’s become drinkable or not ?

Hi how long let them dry before us spray? I used aft 2 days Spraymax2K and got circle print on coasters, no matter what type of mugs /glasses I used.

How long dried before using spray? I let my coaster dry 2 days and after using engine spray the mugs left circle print on it (deep)

How many layers need?

What did it look like with the bottom done?

What grit sand paper did you use?

For the Spray Max 2k clear, did you also activate the hardener thats on the bottom of the can? I can see the red cap on the lid which suggests you might not have...

Great video! I put a coat of Liquitex high gloss finish on my acrylic pour painting. It dried with cracks in the varnish. I actually don't mind the finish it gives it a unique look. This has not happened before. Any suggestions on how to keep the varnish smooth and glossy?

Hi! Have you tried Brite Tone by Crystalac? I'm thinking of using that one...

Where did you get the wood round with the cut out in the back?

I did it again, pour it, tilted, and left a very very thin layer, and it worked beautiful...

It is so hard to hear you. I have my I have everything turned up as high as it will go and that doesn't help.

Does Polyacrylic aerosol not yellow??? Making sure...i use a clear coat as a middle coat, & binder for flakes before brushing expensive sealer/resin on.

I recommend using a Tack Cloth on your products before applying any clear coat or you'll keep getting those bubbles and spots when you spray. The bubbles and spotd are residue on the surface that won't let the clear coat adhere to. You can find Tack cloths at home depot and Lows, its a semi sticky yellow cotton cloth that cleans and picks up any residue on your product so its ready for clear or paint. Nice comparisons !

Sorry it didn't work out did you send down before you applying your spray?and sand down between coats?

try using the wooden keys that fit in the key slots at the corners

Wonderful!!!! Looks so nice!! Thanks for sharing

Thank you so much my daughter we will be very happy!!

Does the KBS diamond produces bubbles ?

You applied these finishes way to thick and to soon between coats.

Eager to see what sealant/final coat you come up with since I too am looking for something that will seal coasters that won't end up with a hot mug sticking to the tile coaster.

Exactly this I did, tilted, and I am in big problem now

Mine are like puddles in two places...

OOOO, I am so happy to find you, I might be able to do a good job out of it, as the painting is spoken for... Thank youuuuu

I understood that 2 coats are enough, unless you want to go for the glass effect... I also got into trouble with varnish, big time, not a groove, but I left a bit too much in 2 places, and it is not levelled. How can I fix that, pleaseeee

You mentioned seeing brush strokes on VHT. Do you spray then use a brush to spread it around?

How long did you let the coasters dry/cure before spray varnishing
