Nano waterproof work

1. Best Overall for Professional Results (Singapore/Asia) Nano-G Nanotechnology: This is widely considered the gold standard for "no-hack" bathroom waterproofing. Why it’s best: It uses a hospital-grade, non-toxic solution that penetrates deep into the grout and tile pores. It is specifically designed to be invisible, which is crucial for dark tiles where traditional sealants look streaky. Bonus: They often include an anti-slip component, which is a lifesaver for polished floors. 2. Best for DIY Maintenance & Shine Nanotol Bathroom Protector: A high-end German "2-in-1" system. Why it’s best: It’s famous for the "Lotus Effect" (water beads up and rolls off). It’s excellent for black tiles because it helps repel limescale and soap scum, which are usually very visible on dark surfaces. It’s a "breathable" coating, so it won't trap moisture underneath and cause the tiles to lift.
