Rockmax Level N11 is a single component thin layer, smooth, self levelling and free flowing cementitious compound subfloor. It is designed for rigid and hard underlayment such as concrete, screed, mortar. The material comprise of selected grade filler, high grade cement and special additive. The mixed material provides free flowing and self levelling mortar. It can be applied up to 3-5mm thickness.
AREA OF USES
Rockmax Level N11 is used to levelling the uneven surface from 3-5mm thickness prior to received floor covering such as vinyl tiles, ceramic tiles, timer floors, carpets, parquet floors, access floors or membranes.
APPLICATION AND INSTALLATION
The surface of substrate must be sound, clean and free from dust, oil, grease, paints and all contaminants on the floor. It is recommended to increase adhesion by mechanical means method such as grinding, light scrabbling. Concrete substrate must be at least 28 days old minimum 1.5 N/mm 2 tensile strength. All cracks, voids, holes must be repair prior to apply material. Small trial areas must be test the adhesion prior apply the whole floor area.
Apply Primer use Rockmax Level Primer and apply on substrate such as concrete or cement screed.
Mixer must be low speed drill (500rpm) with steel paddle. Measure clean water between 5.20 – 5.80 litre for 25kg bag and put into the bucket. Pour material in to the bucket and mix by electrical mixer. Mix for 3 minute until homogeneous. Recheck the mixed material is consistent in color and mortar. The material is ready to pour.
Pour the material on the primed subfloors. Use steel trowel to spread the material. The material will flow within workin g time approximate 20 minute and keep checking the thickness of subfloor by gauge. Use spike roller to remove air bubble immediately. The high ambient temperature (above 35ºC) environment, must be use cool water and work in shade area.
CURING & PROTECTION
No need special curing method. Protect the applied area from wind, moisture, water and sunlight. Do not foot traffic before 4 hours.
