Sikagard® BR-1

CRACK BRIDGING CEMENTITIOUS PROTECTIVE SLURRY

  • A cementitious polymer modified, 2 -components protective coating.
  • It acts as a thin layer coating material for concreteand renders with excellent protection properties.

SikaGard® -BR1 offers the following advantages:
▪ Pre-batch components (No added water).
▪ Brush, roller applied or sprayable.
▪ High adhesion to prepared substrates.
▪ Low consumption per M².
▪ Slightly Flexible.
▪ Good abrasion resistance.
▪ Improves concrete/masonry appearance.
Non-toxic, vapor permeable, allowing substrate concrete to breath.
▪ May be applied to green concrete.

Usage

SikaGard® -BR1 is an economical protective coating for external and internal application of civil structures: above & below ground. It is used as well for sealing hair line cracks in concrete not subject to movement, in marine areas, as corrosion protection for steel bars in repair works, to protect concrete in :
▪ Bridges
▪ Sea walls
▪ Facades
▪ Balconies
▪ Walkways
▪ Concrete exposed to chloride, Carbonation or sulphate environments.
▪ SikaGard® -BR1 is also used for protection of water containment structures.

Application steps

APPLICATION

MIXING


Place ¾ of comp. (A) (liquid) into a suitable mixing container, add comp (B) (powders) to the liquid while mixing.
Mechanical mixing must be used to ensure complete dispersion of the powder component, add the remaining liquid and mix for an additional three minutes, during this process, you may adjust the consistency by adding gradually the final additional liquid.


APPLICATION


▪ SikaGard® -BR1 can be applied by trowel, stiff bristle or spray equipment.

▪ While the concrete substrate is still in a S.S.D. condition, apply the first coat and leave to harden (4 to 6 hours). Apply the second coat as soon as possible, after hardening.

▪ Additional coatings may be applied subject to estimated severity of the local conditions.

▪ After application of the final coating, smooth down the surface of SikaGard® -BR1 with a soft dry sponge.

CURING TREATMENT

To ensure optimal performance of SikaGard® -BR1: Mist water cure for a 48 hours period is recommended. If this is not possible resistance will be provided by the liquid polymer contained in the SikaGard® -BR1 coating.

 

CLEANING OF EQUIPMENT

Clean all tools with water immediately after use.
Hardened material can only be removed by mechanic-

al means.
