Apply Conpatch 600 with a trowel, spatula, float or by spray. By hand press hard. Work up to 20 mm. in one layer. Thicker repairs may be achieved by working in layers.

SUBSTRATE PREPARATION
The substrate should be clean & sound. Remove dirt, dust, oil, grease, laitance, sealers, release agents, curing compounds & paints. Exposed rebar should be cleaned & protected with Congard Zinc.
The concrete should be presaturated for preferably 6 hours with water before application.

PRIMING
Priming is not normally required. Surfaces to receive Conpatch 600 should be well saturated with water first

MIXING
Conpatch 600 is simply mixed with water to yield a stiff easily workable compound with shrinkage compensating properties.The quantity of water depends on the desired consistency but as a guide we recommend 16-18% by weight of Conpatch 600. Mix with a paddle mixer or trowel for at least 3 minutes to ensure a homogenous lump  free material is achieved. Do not try to remix the product after losing workability by the addition of more water.

HEALTH & SAFETY

Conpatch 600 is non-toxic but is alkaline in its nature. When applying gloves & goggles should be worn. Wash off splashes to skin with water. If in eyes wash out with plenty of clean water and seek medical attention. Conpatch 600 is non-flammable.
