Health & safety

Consult the Health & Safety data sheet prior to carrying out any work with this product.

Surface preparation

For the best result, the surface should be blast cleaned to SSPC-SP10 (ISO8501-1 Sa 2½) with a 3 mil (75micron)profile. If grit blasting is not possible the surface should be degreased, loose material removed and the surface roughened to obtain a suitable key.

Application equipment

Short hair stiff brush, trowel, float or mastic type gun.


Remove the lids from both the base and activator. Add between 1% and 2% of adhesion promoter to the base and mix in thoroughly. Add all of the activator to the base and mix thoroughly, ensuring no unmixed material remains. Remove all the mixed material from the base tin and re-mix on a clean flat surface or in a clean shallow receptacle.This product has a relatively short pot life, mix only as much material as you can apply within this period.


This material is intended for use as a filler or grouting materialand can be built up to the required film thickness. It should, where possible, be applied over a primer layer or correctly prepared substrate. Application of films greater than 6mm in one coat should be avoided, to prevent excessive exotherms during cure. Incorporation of the adhesion promoter will substantially improve the bond in all cases, both intercoat and to the substrate.
