SURFACE PREPARATION
Prepare and lay the fresh concrete as per requirements. Note that the concrete must be a minimum of G25 or compressive strength of 25 N/mm².
After the concrete has been screeded, consolidated and further level by bull float. Ensure that any free water present has evaporated or removed in order to proceed to application.
APPLICATION - SW300
Dry shake the Sandwash Hardener SW300 evenly over the surface. The first application of the SW300 should use about 2/3 of the total amount needed. The dry shake materials will absorb some moisture from the freshly prepared concrete and should then be thoroughly floated into the surface, preferably by a bull float. Immediately after this the remainder of the specified amount of the SW300 should be distributed evenly over the surface at right angles to be previous application. This should be thoroughly floated and make sure that an uniform colors is obtained. Final trowelling is best done by hand.
WASHING - SW1.0 Cleaner
After 3 - 7 days of curing, clean the surface thoroughly with a high pressure water jet. Then pre-wet the surface and remove any standing water prior to applying MASTERPAV SW1.0. It is recommended that MASTERPAV SW1.0 be diluted with 1 part SW1.0 to 0.5 part water, but this ratio will depend on the conditions on site. MASTERPAV SW 1.0 is left on the surface for approximately 1 minute then use a heavy duty floor scrubber and running water to remove the cement film and any remaining SW1.0 cleaner. Repeat the process until the surface is exposed to the desired finishing. After the surface is washed to desire finishing, rinse with more water and let the surface dry before applying the sealer.
SEALING
After the floor is dried, apply 2 coats of MASTERPAV Acrylic Sealer series.
