Extra-Large Silicone Craft Mat

The SAPID mat measures 20 by 27.9 inches and is 1 mm thick. Food-grade silicone gives an odourless, non-stick top and a non-slip bottom. The grey surface suits resin casting, clay modelling, painting and general craft work. Heat resistance from minus 30 °F to 210 °F allows use as a counter protector or pot holder.

Sustained Heat And Heavy Use

At 1 mm the sheet resists deformation and tearing during long resin pours or repeated kneading. The non-stick face releases cured epoxy without residue, so cleanup stays quick between batches. The non-slip base keeps the mat fixed on the bench even when tools press hard. The waterproof layer shields the countertop from spills, glue and hot containers throughout a full work session.

Replacing Thinner Craft Sheets

The 1 mm thickness replaces standard 0.3 mm mats that wrinkle, tear or let heat through. Makers who need a single continuous surface for large pours will gain usable area without joining smaller pads. Buyers who want a raised edge to contain liquids or a multi-pack for classroom stations should look elsewhere.

Questions about this item

Does the 1 mm thick, 20×27.9 inch silicone mat stay cool and odor-free when used as a heat-resistant counter protector at 210 °F?

The food-grade silicone is rated from -30 °F to 210 °F, remains odorless and does not deform at the top temperature.

What surface must I already have for the non-slip bottom to grip securely?

The mat grips best on clean, dry, smooth countertops such as laminate, stone, glass or sealed wood.

Will the 20×27.9 inch gray mat cover the full top of my 24 inch deep workbench without overhang?

At 27.9 inches long it extends past a 24 inch depth, giving full coverage with a small overhang on each side.
