Open the can of ClassicLiquid Waterproof Coating and mix thoroughly before adding the ClassicLiquid Thickening Additive.

Open the sausage of Thickening Additive and empty desired amount by hand into the pail (left over material can be sealed and stored for later use). Addition of Thickening Additive depends on specific project requirements, but the recommended amounts is 10-30% by weight. Mix the Thickening Additive gradually into the Waterproof Coating using a low speed mixer, being careful not to introduce air into the mixture, until the required thickness is achieved. Apply the thoroughly mixed material to the previously primed substrate as described in the technical data sheet.

Recommended For:

Waterproofing of vertical flashing details on a roof. Usually these points need several coats of Waterproof Coating in order to achieve the minimum film thickness. By using Thickening Additive the application on these points can be done in 1-2 coats maximum.

Waterproofing and protection of a roof where the substrate is very uneven and may be difficult to achieve a uniform thickness of the membrane. By using Thickening Additive you can modify the rheology of the Liquid Coating so that all areas are covered at a uniform consumption.

Waterproofing and protection of corrugated metal roofs. Once again this application may prove difficult using self-levelling products as once again you will have uneven consumption of material. By using Thickening Additive you can modify the rheology of the Waterproof Coating so that all areas are covered at a uniform consumption.
