Recommended Substrate Conditions

– Concrete must be dry and free from any contamination
(max. 4% moisture content)
– sealer should not be applied at temperatures below 5 °C
– substrate temperature should be at least 3 °C above the dew point

Mixing ratio: by volume; base to hardener 75 : 25
– the temperature of the mixed base and hardener should be above
15 °C, otherwise extra solvent may be required to obtain the
correct application viscosity
– too much solvent will result in lower sag resistance and slower cure
– thinner should only be added after proper mixing
of the base and hardener
– use a soft brush or broom to apply the first coat in order to saturate
the surface. First coat should be applied thinned 5% with 91-92
and allowed to dry thoroughly prior to application of the second
and third coat. Roller application is acceptable for application of
the second and third coats, with the sealer being applied unthinned.
– well trowelled, very dense surfaces such as vacuum dewatered
concrete may only require two coats. The sealer should only be
applied to sand/cement screeds which are not leaner than a
1 : 3 cement/sand ratio.
