Larsen Dustproofer is a silicate-based surface hardening liquid for concrete floors, floor screeds and renders.
Larsen Dustproofer reacts chemically with cement-based substrates to form a microcrystalline seal in the surface pores of the concrete or screed. This produces a hard dust-free finish, which becomes a permanent integral part of the surface, unlike resin based sealers, which slowly degrade on concrete surfaces. It can be used on both new and old concrete floors, floor screeds, etc.
