Single component polyurethane moisture-cure primer
that is water and solvent-free for treating subfloors before
laying wood floors. The low level viscosity and the excellent
penetration make it ideal for strengthening and waterproofing
concrete and anhydrite screeds with a high level of moisture
up to a maximum of 5% M.C. (up to 2.8% M.C. with just one
coat). It is recommended especially for screeds with builtin
heating. Moreover, the absence of solvents makes it safe
for transportation and storage (non flammable product) and
when applied (odourless, it can also be used in the vicinity of
rooms that are in use). Compared with products containing
water, PRIMER SF offers a much higher coverage and does
not increase the humidity of the screed.
