Premixed 2 to 10 mm thick cementitious self leveling underlayment
Vetotop CL530 is a single component cementitious floor self leveling underlayment composed of hydraulic binders, selected aggregates and special additives. It is supplied as a dry powder in pre-weighed bags ready to use on site, once mixed it will form a cohesive self smoothening honey-like flowing mortar that is applied in thicknesses between 2 and 10 mm giving a super flat finish ready to receive final floor coverings including tiles, carpets, resinous flooring systems, parquet, ...etc.
Vetotop CL530 supplied in 25 Kg / Bag. Yield - 1.5 - 1.8 Kg/m²/mm.
Original sealed bag of Vetotop CL530 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded place below 35ºC.
For single bag mixing add to the mixing container 5.0-5.75 liters of water for each 25 Kg bag of Vetotop CL530. Add the powder to the water and mix with a mechanical plaster mixer or low speed electric drill fitted with a suitable paddle for 3 - 4 minutes, until a uniform, lump-free consistency is achieved.
Try to minimize the water addition to get higher strength. Manual mixing is allowed for small batch quantities and mix for approx. 1-2 min or when homogeneous mix is achieved.
Vetotop CL530 can be applied using screw type pump with pumping rate of 25-50 liters/min and length of hose 40-50 LM. and control the water dosage to achieve the required flow.
After placing onto the primed surface, apply by trowel or pin screed. Rake to the Vetotop CL530 spreads and adjust itself to a level floor.
For small areas Vetotop CL530 can be applied manually.
It is advised to spike roll in two directions immediately after application to release entrapped air.
The product is a self-curing product and should be left undisturbed for 3 to 5 days prior to use of subsequent toppings.
The applied product should be protected from environmental agents such as wind, direct sunlight, dirt and dust exposure to insure smooth leveled hard surfaces for at least the first 24 hrs.
The surface should be sound, clean, free from loose material, grease, laitence, dirt curing compound, etc.
Larger areas can be divided with wooden battens to control the pumping volume and determine the layer thickness to be applied.
Prime the surface with Vetoprime PB433 diluted with potable water (ratio of 1:1.5). Mix thoroughly and spray or brush onto the floor without pooling. Its important to note that if the primer dried it will become a debonding layer and - thus make sure to apply the material within the primer open time. Allow the primer coat to be tacky when applying Vetotop CL530. Alternatively where large areas are to be applied, prime the floor with Vetobond EB431 which will allow for long open time.
Vetotop CL530 is highly alkaline therefore avoid direct contact with eyes or skin. It is recommended to use protective gloves and goggles during application. Any skin contact should be wash with soap & water. In case of eyes irritation, immediately wash with copious amount of clean cold water. Seek medical advise.
Vetotop CL530 is non-flammable.
