Questions about
NSA T-20
Can NSA T-20 be used over existing tiles?
Yes. It is developed for tile-on-tile work. The old surface must be sound: remove loose or hollow tiles and clean it before you start.
Which tile sizes does NSA T-20 suit?
Medium ceramic and vitrified tiles, including 2×2 ft, 2×4 ft and up to 32×64 inch. For larger formats, choose NSA T-20 Plus or NSA W-20.
How much area does one bag cover?
About 2–3 sq. ft. per kg at 3 mm with a 6×6 mm notch trowel, so roughly 40–60 sq. ft. per 20 kg bag, or 80–120 sq. ft. per 40 kg bag.
