The technology is simple, the result is impressive: mosaic tiles decorate simple tables and transform chests of drawers into real eye-catchers. A round mosaic table is a beautiful accessory for the terrace, balcony and garden.
The basis for the mosaic table is a special metal frame, available in hardware stores or online shops for mosaic accessories, into which a plywood sheet is inserted. Of course, you can also decorate existing tables or similar with the decorative small mosaic stones. However, you should make sure that both the tiles and the other materials used are suitable for outdoor use.
Good to know:
Tiles with a maximum water absorption of 0.3 percent are considered waterproof and therefore frost-resistant. This includes natural stone tiles, stone or porcelain stoneware and some glass mosaics. You can get finished stones in hardware stores or in craft stores.
Tile fragments are easy to make yourself: Carefully smash whole tiles into pieces with a hammer. To prevent the broken pieces from flying around, wrap the tiles in a towel beforehand!
You can let your creativity run free when arranging the mosaic. You can design an abstract pattern or – for advanced users – lay the mosaic according to a template. In both cases, it is advisable to arrange the mosaic stones or tile fragments on the table top until you are satisfied with the result.
Make sure that the materials are coordinated. For tile fragments made of natural stone, you use special natural stone glue and mortar. These prevent discoloration, are frost-resistant and weatherproof.
1. Apply tile adhesive and lay tiles
First you treat the plywood sheet on both sides with shower and bath sealant to protect it from moisture. After drying, apply the flexible adhesive with a smoothing trowel and comb through it with a notched trowel. You lay the natural stone tiles from the outside in, preferably with the straight edge to the edge. The distance between the tiles should be two to six millimeters. The tile adhesive must then dry. The self-designed table can be grouted after about three hours. Use a grouting board to add the mortar. Use this to stroke the joints diagonally several times until they are completely filled.
2. Peel off mortar and clean tiles
Peel off the remains of the grout. After about 15 minutes, use a sponge board to smooth the joints and wash off the mortar. You can now polish away the last veil of mortar with a cotton cloth. So that the joint between the table frame and the mosaic can later be properly sealed with natural stone silicone, it must be cleaned. Remove any mortar residue from the edge joint. Then apply the elastic silicone mass along the outer edge and smooth it out with a putty knife. Then let it dry!
Tip: Avoid discoloration
Many natural stones have a porous structure and are usually not sealed on the underside or the plate edges. That is why excess water from gray tile adhesives and colored grout can penetrate the stones through the pores and cause unsightly stains.
Special tile adhesives and grout for natural stone prevent the tiles from staining. The white, non-translucent natural stone tile adhesive and the natural stone grout dry much faster and prevent excess water from being deposited in the stones. The two products are also frost and water resistant.
