ceramic coasters for painting are the number-one impulse buy that trips up new makers: pick a glazed tile or a too-thin blank and your paint beads, peels, or soaks through. That mistake costs hours of work and a ruined batch of pours. These 12 unglazed rounds give you a consistent, porous base that accepts pigment, resin, and varnish without surprise.
Each set contains 12 round ceramic tiles and 12 adhesive cork pads – a simple combo that turns a craft afternoon into a stack of gift-ready coasters. Want to skip the first-time frustration and actually finish a project that looks good on the table?
Key Features & Real-World Use
- 12 ready-to-decorate blanks – Twelve identical 4.2 in unglazed ceramic rounds give consistent absorbency for acrylic pouring, alcohol ink, and brush painting.
- Adhesive cork pads included – Stick-on cork adds non-slip grip and prevents table scratches without extra hardware.
- Porous, paint-friendly surface – Unglazed ceramic soaks in pigment and primer evenly; great with pouring medium, epoxy resin, or mixed-media varnish.
- Craft-room friendly – Small form factor fits on a silicone mat or turntable; pairs well with brushes, palette knives, and squeeze bottles.
- Durability + finishing – Ceramic base resists cracking under normal use; seal with epoxy or clear varnish for stain resistance and a glossy finish.
How to Choose
- Surface finish – Unglazed ceramic is ideal for paint adhesion; glazed tiles are slick and often need sanding or primer.
- Size and fit – 4.2 in diameter is a standard coaster size; check cup base diameters and coaster trays if you use sets.
- Included accessories – Adhesive cork pads save time and provide a finished underside; look for pre-cut pads if you dislike trimming.
- Compatibility – If you plan epoxy resin pours, pick tiles with minimal warping and seal edges to prevent resin bleed-through.
- Project goals – For alcohol ink effects choose highly absorbent blanks; for glossy resin art, focus on flatness and even thickness.
Quick Setup & Use
- Prep your workspace: lay a silicone mat, gather acrylics, pouring medium, epoxy resin, brushes, and a heat gun or torch.
- Lightly sand edges if needed, then wipe with a tack cloth to remove dust – this helps sealants adhere.
- Apply paint or pour mixes: for alcohol ink drip, use blending solution; for epoxy, mix carefully and pour in thin layers.
- Let layers cure between steps. Sand between coats if you want a slick, glass-like finish before a final resin topcoat.
- Peel and stick the included cork pads under each tile for grip and furniture protection.
Buyer Doubts Solved
Will paint stick to these tiles? Yes. The unglazed, porous ceramic surface grips pigment, so your acrylics, alcohol ink, or resin sit evenly without sliding off.
Are they hard to finish? Not really. Use a basic sealant or epoxy for drink-safe surfaces and the cork pads for underfoot protection.
What about warping or cracking? These craft tiles are flat and designed for decoration – avoid extreme heat like rapid kiln firing unless you are experienced with ceramic firing.
Do I need extra tools? Minimal extras: a silicone mat, mixing cups for resin, a small torch for bubbles, and sandpaper. That’s it to get professional-looking results.
These 12 blanks plus adhesive cork pads are a low-risk way to ramp up your craft output, test techniques like acrylic pouring and alcohol ink, and make wedding favors or housewarming gifts quickly.
