Coating Installation

Xypex coating is applied with a semi-stiff nylon bristle brush, push broom (for large horizontal surfaces), or specialized spray equipment.


Mixing Instructions

  1. Mix Xypex with clean water only (potable water that is free of salt and other deleterious materials).
  2. Mix Xypex powder into the clean water with a paddle on a slow speed electric drill (250 RPM) or with other equipment that ensures adequate mixing. For small jobs, Xypex may be mixed by gloved hand or by trowel.
  3. Be sure that the quantity mixed can be applied within 20 minutes. As the mixture thickens, stir briefly to refluidize the mix but do not add water.

Mixing for Slurry Coat

Mix Xypex powder with clean water to a creamy consistency in the following volume proportions:

For Brush Application 
1.25 - 1.5 lb./sq. yd. (0.65 - 0.8 kg/m2)
5 parts powder to 2 parts water

2.0 lb./sq. yd. (1.0 kg/m2)
3 parts powder to 1 part water 

For Spray Application 
1.25 - 1.5 lb./sq. yd. (0.65 - 0.8 kg/m2)
5 parts powder to 3 parts water
(ratio may vary with equipment type) 

Mixing Dry-Pac 

    Using a trowel, mix one part clean water with six parts Xypex Concentrate powder by volume for 10 - 15 seconds. Lumps should be present in this mixture. Do not mix more than can be applied in 20 minutes.

    NOTE: Where a smooth, steel-trowelled finish is required for horizontal slab or where slab will be exposed to traffic (e.g. parking deck), apply Xypex Concentrate DS-1 or DS-2 by dry shake method. Consult Xypex Technical Data or your Xypex representative for further information.
