APPLICATION

Surface Preparation:

Ensure the concrete surface is completely free of stains, oils, form coatings etc. to obtain good adhesion of Concure A99 and to avoid discoloration or uneven surface effects.

Mixing:

Stir contents thoroughly before using.

Placement:

Spray Concure A99 evenly over the freshly laid concrete as soon as possible after final trowelling just after the disappearance of surface bleed water. If spray equipment is not available, apply with a soft brush, broom or wide nap roller as soon as the concrete surface is hard enough. Apply to vertical surfaces immediately after the formwork has been removed. Apply at an even coverage rate of not greater than 5 square metres per litre.

Clean Up:

Remove from tools and equipment with water immediately after use.

Storage:

Shelf life of 12 months if kept in a dry store in the original, unopened packs.

Yield:

Apply in a single coat application at a coverage rate of 5 sqm per litre. Can be applied at other coverage rates to achieve the desired water retention efficiency.
