The best non toxic stain to use for timber tables, bench tops and floors is NanoTech. NanoTech is a high performance Water-Based Nano-Polymer Acrylic Sealer which leaves a protective membrane on the wood and concrete surface that both waterproofs and seals. It contains no silicones, waxes or oils and does not fade, yellow, chip or peel when properly applied. It will enhance the color of the wood and give it a "wet glossy" look. Dries to touch in 30-40 minutes. Nano Tech penetrates deeply into the pores providing unusual durability and protection!
