Mapei - Ultraplan 1 Plus - Quick-Setting - Powder Self-Leveling Underlayment Compound

By Mapei


Mapei's Ultraplan 1 Plus is a quick-setting self-leveling compound and underlayment engineered to smooth out surface imperfections up to 1-1/2" thick and level interior concrete and approved flooring. This compound can withstand light foot traffic after 2-3 hours of application and auto traffic after 3 days. However, it is intended for dry interior areas; for external uses and areas prone to prolonged moisture, an exterior-grade topping or screed from MAPEI is recommended and waterproofing may be necessary. Additionally, expansion and control joints must be taken into account around all walls, columns, supports and equipment pedestals.
