Premixed 2 to 10 mm thick cementitious self leveling underlayment
Vetotop CL530 is a single component cementitious floor self-leveling underlayment composed of special cement, 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.
- Factory controlled pre-blend ensures consistently high quality.
- Suitable for Middle East harsh weather conditions.
- Easy application enabling high productivity & superior finishing.
- Rapid commissioning and serviceability.
- High bond to the substrate.
- Excellent physical and mechanical properties.
- Shrinkage compensated.
- Excellent workability.

Vetotop CL530 is supplied in 25 kg/Bag.
Yield - 15lit/25kg Bag.
Stated consumptions data are for general guidance. Actual consumption depends on the nature of the substrate, method of application, and wastage.
An original sealed bag of Vetotop CL530 has a shelf life of 6 months provided it is stored clear of ground in a dry and shaded place below 35ºC.
Mixing & Application
For single bag mixing, add to the mixing container 4.8 - 5.2 liters of water for each 25kg 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 fluid consistency is achieved.
Do not mix material that can not be applied within 20 min. The mixed material retains flow-ability for about 20 min in room conditions.
Placing should be directly from the mixing container on top of the primed substrate, always start from in to out and narrow areas. It is very necessary to pour the material continuously without any time gaps more than 10 - 15 min between the newly poured and the previous adjacent one, which is to ensure a perfect leveled convergence.
After placing onto the primed surface, assist spreading the material by the leveling smoothing trowel or by a pin gauge rake. Use a suitable spike roll to remove entrapped air if there is any.
Curing
Vetotop CL530 is a self-curing product. Protect the applied material from environmental agents such as wind, direct sunlight, dirt, and dust exposure for at least the first 2 hours to ensure smooth leveled hard surfaces.
The surface should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc.
Larger areas can be divided with wooden battens to control the pouring volume and determine the layer thickness to be applied. Follow the expansion joints in the substrate for segmenting the area under the application.
Priming the substrate is vital, use Vetoprime PB433 diluted with potable water (ratio of 1:1.5). Mix thoroughly and spray or brush onto the floor without pooling.
Before applying Vetotop CL530, its important to leave the primer between 1-2 hours to fully dry. In case of doubt, check the primer dryness by adding drops of water on top of the primer substrate, it should not absorb the water drops.
- Do not mix with any additives or products, unless recommended by Saveto. Mixing water should be clean and its temperature between 20 - 30ºC.
- Make sure the substrate is suitable for the underlayment application. In case of doubt, try on the sample area to assess its suitability.
- Vetotop CL530 is not recommended to a forklift or heavy loads.
- Do not apply the product at a temperature less than +5ºC or more than +35ºC, the setting behavior is highly affected by surrounding temperature.
- Tools should be cleaned with water before the mortar hardens. After the hardening, its residuals can be removed mechanically only.

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 eye irritation, immediately wash with a copious amount of clean cold water. Seek medical advice.
Vetotop CL530 is non-flammable.
