TECNOCOAT P-2049 lv, pure polyurea for protecting and waterproofing polyurethane foam


We present the new TECNOCOAT P-2049 LV pure polyurea membrane, designed specifically for protecting and waterproofing roofs that have been thermally insulted with polyurethane foam.

The initials “LV” are the abbreviation of “low viscosity” and they refer to the main characteristic that differentiates this polyurea from the rest of the TECNOCOAT P-2049 range, given that once it has been applied it forms a membrane with greater elasticity and elongation, providing better stability and durability.

TECNOCOAT P-2049 LV’s versatility and the fact that it dries in 3 to 5 seconds, means it adapts to any surface, making it the ideal product for application on uneven areas of any shape, whether curved or with corners. 


TECNOCOAT P-2049 LV is applied using high pressure and temperature spray equipment; however, its great advantage is that it can also be applied using a polyurethane foam spray machine.

TECNOCOAT P-2049 LV can be sprayed directly on TECNOFOAM foam provided no more than 48 hours have elapsed since its application. If more than 48 hours have elapsed, simply apply a thin coat of PRIMER EPW-1070 primer.
