TECHNONICOL Mastic No. 33 — water-emulsion bitumen-latex, for spraying

Mastics and liquid membranes

Mastic No. 33 is applied with a two-channel metering unit: the latex-modified bitumen emulsion and the calcium chloride solution are fed separately, after which the coating sets within 1 min. The composition contains no solvents, the coagulant is included in the delivery, and the material can be applied to concrete with a moisture content of up to 10%. The mastic protects foundations, basements, bridges, tunnels and piles, pool floors, balconies and non-potable water tanks, and is also suitable for seamless roofs. Elongation is at least 1200%, watertightness is 0.3 MPa for 24 h, and heat resistance is not lower than +140 °C.
