SikaBond® SBR+

SikaBond® SBR+

Waterproof general purpose bonding agent and mortar mixture

SikaBond® SBR+ is a white liquid, which has numerous uses as an admixture, primer, bonding agent and sealer. Polymer emulsions of this type have been used extensively over the last 20 years by the building industry as 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.

  • Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc.
  • Mixes may be applied in much thinner sections.
  • Excellent resistance to water and water vapour
  • A high level of resistance to salt permeation
  • Much improved toughness and flexibility
  • Reduced surface dusting of concrete
  • Greatly improved resistance to many chemicals- ideal for use in dairy parlours etc.
  • Reduced water: cement ratio for equivalent workability
  • Improved frost resistance
  • SikaBond® SBR+ is also freeze thaw stable.

Usage

  • As an admixture for mortar/screeds/renders.
  • As a bonding agent for screeds/renders.
  • As a primer/sealer in tiling applications.
  • As a flexibliser for cementicious based tile adhesive when tiling on wooden/asphalt floors.
  • In addition, SikaBond® SBR+ has the advantage over PVA bonding aids in that it is not adversely affected in wet conditions and is therefore recommended for exterior use.

Shelf Life

12 months in original unopened containers.

Storage Conditions

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

Application

Application steps

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 latex modified mortars owing to the plasticising effect of the latex. The mix design depends upon thickness and intended use. However, typically mixes for a 12mm topping or screed are as follows:

                               Screed     Topping
O.P.C                      1              1
Moist sand            3.5           1.75
3mm Washed

Granite                  0             1.75
SBR+                      0.2          0.2 (ie. 10L per 50Kg 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. Once dried use solvents such as white spirit with a coarse wire brush.
