When the tile grout has dried, the mosaic looks really good. The grout looks a bit chalky though and doesn't blend well with the rest of the glossy mosaic tiles. Not only that, the tile grout powder sometimes has the tendency to stick to your fingers when handling the pot.
And this is where you need to seal the grout with a tile grout sealer. The tile grout sealer penetrates the grout, fills and seals it. It leaves a waterproof surface with a shiny finish.
Sealing the Tile Grout
- The tile grout sealer is liquid and there's nothing to mix. However, do shake the tile grout sealer well. Spray some of the sealer on the mosaic garden pot. After spraying, spread the liquid around on the tile grout rather than on the tiles with your fingers. You may also use a small paint brush to apply the sealer on the grout.
