Why care homes use this

Care home wet-room floors require a levelled, waterproof-compatible bed that will not crack under thermal cycling from underfloor heating or frequent wet/dry cycles. Latex Plus provides the bond strength and flexibility that a straight cement:sand mix cannot achieve in these conditions.

Key specification

Latex polymer additive; mix ratio 1:1 with water or neat; improves adhesion class to C2 when used with cementitious adhesives; suitable for underfloor heating beds up to 40°C.
