Thorough substrate preparation is essential.
Cut back concrete to a vertical lip of 10mm at edge of repair area.
Remove all loose material – wire brushing is advisable. Clean back any exposed reinforcing steel to bright metal and protect with Steel Primer.
Sweep clean or vacuum. The surface must be free from grease, oil or any other contaminants. A gas torch will help to remove oil from the surface. If this is not practical, Polycote Degrease IT may be used to clean the area but this must be thoroughly rinsed off, and the substrate should be DAMP, BUT NOT WET when Cretex Rapid is applied.
Dry substrates should be lightly dampened with water to reduce suction immediately before priming.
Having prepared and dampened the repair area, prime the surface with a small quantity of the liquid component, mixed with powder at a ratio of 1 part liquid to 2 parts powder by weight.
Allow the primer to become tacky (approximately 20 minutes at 20oC) before applying the mortar mix.
Do NOT allow the primer to dry.
The recommended mixing ratio of powder to liquid is 9:1 by weight. Pour the appropriate quantity of liquid in a suitable mixing bucket and gradually add the powder whilst mixing until a slump-free trowellable consistency is obtained. Mix thoroughly using a heavy duty slow speed drill and mixing paddle for 1 – 2 minutes to ensure activation of the plasticiser and thorough particle distribution.
The consistency of the mix may be adjusted (thicker/thinner) depending on the type of repair, but bear in mind that excess liquid will reduce the strength of the product.
Do not mix more than can be applied in 5 minutes.
Having prepared and primed the substrate, apply the material with very firm pressure using a 7" gauging trowel or 10" steel trowel.
Should hardening occur prior to finishing, the trowel may be dipped in water to extend the working life of the product.
To form coving – apply Cretex Rapid as a small quadrant using a 7" gauging trowel, finishing with a steel coving trowel. (Tip: a satisfactory result may alternatively be achieved by laying a glass bottle horizontally into the coving and running it along the length, pressed firmly to the floor and wall surfaces).
