Excellent adhesion to steel and concrete. Adheres well to brick, tiles, glass, asphalt, wood, expanded polystyrene and most building materials. Mixes may be applied in much thinner sections.

Styrene Butadiene-based waterproof bonding agent, primer and mortar admixture

SikaBond® SBR is a styrene-butadiene co-polymer, which has numerous uses as an admixture, primer, bonding agent and sealer for use in areas subject to humidity, dampness and water contact. Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds. An admixture for cement and concrete applications, including repair and renovation, surfacing of floors and bonding generally. It contains anti-foam to control the density of cementitious mixes.

Usage

Component to improve concrete repair.
Component to improve external rendering.
Waterproofing and tanking mortar preparation.
For corrosion protection of steel.
Silage pit lining and protection.
Admixture for mortar, screeds and renders.
Bonding agent for screeds and renders.
Primer and sealer in tiling applications.
Recommended for exterior use, unlike most PVA bonding aids.
Flexibliser for cementicious-based tile adhesive when tiling on wooden or asphalt floors.

Advantages

Excellent adhesion to steel and concrete.
Adheres well to brick, tiles, glass, asphalt, wood, expanded polystyrene and most building materials.
Mixes may be applied in much thinner sections.
Excellent resistance to water and water vapour.
A high level of resistance to salt permeation.
Increased toughness and flexibility.
Reduced surface dusting of concrete.
Prevents bleeding.

Product Details

Shelf Life

12 months from date of manufacture when stored according to manufacturer’s instructions in original, unopened containers.

Storage Conditions

SikaBond® SBR is best stored at moderate temperatures (+5 to +30 °C) to avoid the possibility of permanent damage occurring due to prolonged heat or excessive cold. However if frozen, the product should be thawed slowly. SikaBond® SBR should preferably be stirred before use. SikaBond® SBR contains sufficient bactericide to preserve the product under normal storage conditions.

Density

Application

MIXING

Mixing procedures for topping and screeds containing Sikabond® SBR are similar to those used to conventional compositions, with gauging water partly replaced by Sikabond® SBR. However, mixing time should be minimised to limit air entrainment. Mixing should be carried out in a forced action mixer. The usual procedure is to pre-mix sand and cement in the mixer, pour in the Sikabond® SBR, mix for 1 – 3 mins, then slowly add water to the required consistency. NB: Over-addition of water causes rapid thinning of Sikabond® SBR modified mortars owing to the plasticising effect of the Sikabond® SBR. The mix design depends upon thickness and intended use. However, typical mixes for a 12 mm topping or screed are as follows:

Screed Topping

O.P.C 1 1

Moist sand 3.5 1.75

3 mm Washed Granite 0 1.75

SBR 0.2 0.2
(ie. 10 L per 50 kg of cement)

Water As required As required

All parts are by volume of uncompacted material.

CLEANING OF TOOLS

All tools should be cleaned immediately after use with water because hardened SikaBond® SBR modified toppings and screeds have excellent adhesion and are therefore difficult to remove. Solvents such as white spirit can be used with coarse wire wool to help remove partially hardened mortar.
