The surface should be clean, dry and free of any loose chippings/debris (the treatment and removal of any weeds and moss should be carried out prior to laying preparation). Use masking tape to protect any kerbs/ironwork etc. from being covered (this is to be removed when the surface is completely dry, after the whole application is complete).


Mix thoroughly before use using a drill paddle.

Pour onto the surface in manageable amounts and using a soft brush with handle or squeegee, spread evenly over the surface to the recommended thickness of approximately 1.5mm-2mm, promptly finishing this area in the same directional brush stroke.

If a thickness greater than approximately 1.5mm-2mm is required we recommend an additional application but it must be ensured that the first application is set fully before reapplying.

The material should be applied on a dry day at temperatures of 10 °C and rising with no possibility of rainfall. Setting times vary with temperature. At the recommended thickness setting times will be, at 25°C approximately 1-3 hours and at 10°C 3-6 hours.


1 x 25kg bag will cover approximately 10-14m² @ 1.5mm-2mm thickness, depending on surface texture.


Colseal is supplied in 25kg buckets (36 x 25kg per pallet) or cardboard boxes containing 40 x 25kg bags.
