Sika SikaBond SBR+ 25 Litre Waterproof Bonding Agent

MPN: SIKASBR25

Barcode: 5055492700537

SikaBond SBR+ is a one component, water based, general purpose, styrene butadiene rubber emulsion.

When diluted with water it produces a gauging solution for improving adhesion, workability and waterproofing of mortars and cementitious mixes.

Sika SBR has numerous uses including as an admixture in
mortars, screeds and renders, as a primer or sealer in tiling
applications and a bonding agent for screeds or renders.

Unlike PVA SBR + is not adversely affected in wet conditions and is therefore recommended for exterior use.

Reduces water to cement ratio for equivalent
workability in mortars, making it easier to spread and allows mixes to
be applied in much thinner sections
.

It contains anti-foam to control the density of cementitious
mixes.

SBR Uses:

As a water resistant bonding agent for external rendering and screeds

Admixture for concrete repair, brick slip and tile fixing mortars

For improving resistance to abrasion, chemicals and oils

Repair and renovation, surfacing of floors and bonding
generally.
