Keepsake resin tile coaster

If you have been reading the Resin Obsession blog for awhile, you might remember last Fall when I used resin as a glaze for decorative tiles.  Quite frankly, I wasn’t super thrilled with the results, although my kids’ grandmother loved the gift.  I wanted to try the project again and did so this week.  I made a few tweeks, including using a new clear epoxy resin as the glaze.

I had my kids draw on the tiles again, but this time, they used ‘paint’ markers.  These are markers that contain real paint.  In doing my research, many suggested that they only needed a day to dry and didn’t require any oven time at all.

After my kids decorated the tiles (generic, glossy white, ceramic tiles from the home improvement store), I let them sit for approximately 36 hours.

This time, I also wanted to try coating them with a layer of the Alumilite Amazing Clear Cast Resin.  This resin is NEW to the Resin Obsession store.  The thing I was most excited to learn about this resin is that it is FDA food safe.  That means you can create your own resin cups, plates, utensils, etc., with this resin, and it is safe for food and drink contact.  How cool is that?

Mixing Amazing clear cast resin

This resin mixes as a 1:1, either by weight or by volume.  I measured 1.25 ounces each of Part A and Part B to cover my two 6 inch square tiles.  (I won’t go into the math here, but if you want to know how I calculated how much to mix, you can read the formula in this blog post on how to resin a painting.)  Note:  This resin mixes really thick.  I can’t stress enough that you need to be careful when mixing so as not to introduce any more bubbles than possible into this resin.

pouring clear epoxy resin over a ceramic tile

I propped up my tiles using a tuna fish can.  The layer underneath was styrofoam with a layer of wax paper.  You can see here how I like to make my own resin crafting trays.  Even though this resin has a 45 minute pot time, I didn’t want to waste any time getting it onto the tiles.  I poured it onto approximately two-thirds of the tile and waited for it to spread.   I was immediately impressed with how clear this resin was as compared to the Envirotex Lite.

I then used a stir stix to help me draw the resin to the edge.

With this time as well, some of the resin dripped over the edge. I tried to get as many as possible while it was still liquid, but alas, I didn’t get them all.  I covered the tiles and let them cure.

After 24 hours, it was a cured finish, although the manufacturer says to allow 2 1/2 days for a full cure.  Not shown:  I used a dremel tool to remove the resin drips and applied felt feet to the back of the tile.  You can see my technique when I made resin tiles earlier.

I was much happier with my results on this tile than the ones I did a couple of months ago.

1.  The pen colors stayed brighter and didn’t turn muddy.

2.  The Alumilite Amazing clear cast resin was much clearer (no yellow tint) as compared to the Envirotex Lite. They were both very thick and I had to worry about bubbles, but I would definitely use the clear cast again for a similiar project.

you said you ‘covered the tiles’ and let the cure…. what did you cover the tiles with and how did you cover them/?


@leslie, I used a large plastic dome that rested on the styrofoam platform.


@leslie, I covered them to keep dust and hair off of them while they were curing.


Awesome! I knew some resins were food grade (I think people use them to make teething necklaces and such) but I had no idea that Alumilite’s Clear Cast was! Now I’m wondering if their quick-curing opaque product is as well. I’ll have to look into that.

I’ve done a similar project with my toddler for her grandparents, except I did her handprints on them instead of a drawing. Since I was using it on her skin, I used a water-based paint that would wash off her hands easily. I then sealed the tile with several coats of ModPodge to avoid any fading or smearing and that seemed to work really well. It might help with the sharpies as well, but I can’t say for sure.

Thanks for the great post!

Thanks for the comments. 🙂 FYI — The Amazing casting resin is not food safe.

Can the coasters then be used for hot drinks using the Amazing Casting Resin?

Scratch resistant?

Katherine Swift

I think this resin cures hard enough for coasters. They are fairly scratch resistant. They can handle hot beverages in a cup, but not a hot cup straight from the microwave.


I have tried twice with the alumalite clear on tiles and
So manybubbles showed up they were ruined . I had the resin for a while but the seals were never broken,
