Temperature limitations

Himfloor FC450 should not be applied at temperatures below 10°C, nor at a substrate temperature which is lower than the dew point temperature plus 3°C. The maximum application temperature is 35°C .The maximum relative humidity is 80%

Surface preparation

It is essential to thoroughly prepare the floor surface in order to achieve a Sound, clean and dry substrate, preferably by blasting. Substrates, contaminated by oil or grease, should be cleaned with suitable cleaning agents, followed by cleaning with lots of water. Allow the floor to dry for at least 48 hours.


New cement based floors should be at least 28 days old and give a hygrometer reading not exceeding 5% (Protimeter).Vapour pressure may result in de-bonding of the finishing coat. It is essential to carry out the “rubber mat” test.Craks or movement in the substrate, may re-appear in the finish coat. Existing dilations should be repeated in the finish coat.


If required, a primer may be used, provided Himfloor FC450 R or P is applied within 24 hours.


The pigmented base component (A) of Himfloor FC450 should be thoroughly homogenised before mixing it with the hardener component (B) .Mix further for at least 3 minutes .
The use of a heavy duty slow speed drill fitted with a mixing paddle is desirable.


The mixed Himfloor FC450 should be applied to the prepared surface in 2 coats, using a roller, ensuring that the rolling takes place in straight lines and cross-wise. The second coat may be applied as soon as one can walk on the floor, but within 24 hours .The waiting time depends on the condition of substrate and surroundings. If the second coat is applied after more than 24 hours, the substrate should be prepared again.


Disposal of spillage or empty packaging should be in accordance with local waste disposal regulation .
