What to do:
Step 1: Recycle and old doormat, or cut a sheet of rubber to size (Many larger fabric stores offer various rubber products for various upholstery projects).
Step 2: Before sticking down the pebbles, arrange them on the rubber mat until all the pebbles fit nicely.
Step 3: Use Pattex Universal Silicone to attach the individual pebbles to the rubber mat. Apply a thick bead of silicone to the back of each press and press firmly onto the mat.
Step 4: Once you have finished sticking down all the pebbles, leave to cure for 24 hours.
After that you can leave as is, or you can apply a satin on gloss spray varnish over the top.
What you need:
1. Assorted pebbles or river rocks - Select pebbles of approximately the same size, and ones that will be easy to stick down
2. Rubber mat
3. Pattex Universal Silicone
4. Dropcloth or newspaper
5. Rust-Oleum clear polyurethane spray varnish (satin or gloss)
Estimated time needed: 30 minutes plus drying
