SBR Bonding Agent
Construction Chemicals SBR is a white styrene butadiene emulsion used to improve the properties of cement renders, screeds and mortars. It is also used in conjunction with Construction Chemicals Tanking Slurry as a priming coat or tight render basecoat. Used with Sulphate resistant cement it will resist the movement of salts with in wall.
USES:
- High strength floor screeds.
- Patching and repair mortar.
- Thin section screeds.
- As a bonding bridge for renders and Waterproofing.
- Waterproof renders and screeds.

Tensile Strength: 20- 30
Abrasion Resistance: up to 200%
Density: Approx 1.01
Bonding Grout: 4M2/L depending on surface and application technique
Mortar: See Mixing Table
APPLICATION
Mix as per Table. Do not use neat SBR as a bonding grout, without adding cement. Maximum dilution of SBR with the gauging water is 1:4.
Free fall mixers are not suitable for SBR mortars; the higher performance forced action paddle type mixers are recommended for more efficient and speedier mixing of the mortars. For small quantities a slow speed drill and paddle is ideal.
Always keep the water/cement ratio to a minimum to enable correct working and compaction. A W/C ratio of less than 0.4 is advised.
Thick screeds should be laid in layers of 20mm thoroughly compacted and immediately followed by another 20mm, this repeated until the required thickness has been applied.
Mortar toppings should be finished by wood float or steel trowel. Care should be taken to prevent rapid drying of SBR mortars, by the use of polythene, damp hessian or concrete curing compounds. Always use sharp, clean and washed sand.
Maximum thickness per layer 40mm laid and compacted in two layers, as above.
Ensure hardened layers are mechanically "keyed", wetted and grouted.
Renderings, floor toppings etc., should be allowed to cure correctly.If temperatures drop to 2oC or less, protect the uncured mortar against frost.
Do not overmix SBR modified mortars. Do not “feather edge” SBR modified screeds.
METHOD OF APPLICATION
Preparation
The substrate must be free of all oil, grease, existing sealers or other contaminants. All loose material should be removed and a key provided using a scabbling machine or enclosed grit blaster. The surface should be well soaked with water prior to application of the bonding agent. Do not allow ponded water to remain on substrate.
Priming
Use of Construction Chemicals Bonding Grout. Mix 1 part by volume SBR with 1.5 parts fresh Portland cement to produce a stiff grout. Scrub this grout on to the pre dampened concrete or wall. DO NOT allow to dry prior to the application of subsequent layers.
