Application Instructions

Surface preparation

When completing patch repairs to concrete elements ensure that the surrounding concrete is clean and free of dust, plaster, oil, paint, grease, corrosion deposits and any other deleterious substances. Laitance should be completely removed by high pressure water blasting, grit blasting or a combination of both. Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. Any remaining dust or loose material should be blown clean with oil free compressed air.

Estopatch Fine should not be applied if the substrate is subject  to moving water.

Priming

For a durable finish all surfaces should be thoroughly soaked prior to use ensuring that there is no residual surface water.

For optimal performance a layer of Estobond Acryl shall be applied.

Mixing

Estopatch Fine can be hand-mixed for small quantity. For large quantity a pan mixer or a slow speed drill fitted with spiral paddle shall be used. Add 7.0 – 7.5 litres of water per 25 kg bag, depend on the mix consistency needed and mix for 3 – 4 minutes. The yield is about 15 litres per 25 kg bag of Estopatch Fine

Application

Application of Estopatch Fine should be by steel trowel from a “feather edge” to 3 mm. Estopatch Fine should be applied to the complete area requiring treatment and be allowed to partly set before finally trowelling to a smooth finish. If a very smooth surface is required a small amount of water may be flicked onto the surface of the Estopacth Fine with a paint brush prior to final trowelling. Estopatch Fine may also be finished with a sponge float.

Cleaning

Estopatch Fine should be removed from tools with clean water immediately after use. Cured material can only be removed mechanically.
