Floor Levelling Compound
Description
Durabond Floor Levelling Compound is a cementitious floor levelling and smoothing compound in powder form requiring only the addition of water. Durabond Floor Levelling Compound can be easily spread on to suitably prepared stable substrates in order to smooth surfaces, prior to laying final floor coverings.
For levelling and smoothing concrete and screeded floors prior to laying final wearing, coverings such as carpets, sheet vinyl, tiles etc.
Advantages
- Self smoothing
- Sets hard within 1-1.5 hours
- Coverings may be laid 6-8 hours after application
- Pre-blended requiring only the addition of water
- Easy to use
Preparation
The floor to be treated must be free from dust, loosely adhering material, plaster and cement droppings, grease, oil and paint, and any contaminants which may prevent adhesion.
All surfaces should be sealed using Durabond Floor Levelling Compound PVA, diluted with water at a rate of 1 part Durabond to 3 parts water.
Very smooth, non porous surfaces (such as terrazzo or quarry tiles) should also be primed in this manner, and allowed to dry, then apply a bonding coat of 1 part Durabond to 2 parts water and allow to become tacky. For extremely porous substrates it may be necessary to apply a number of coats to seal the surface (Refer to Durabond PVA Product Data Sheet)
Mixing and Laying
Slowly add 4 parts of Durabond Floor Levelling Compound to one part water and stir to a creamy consistency using suitable mixing equipment. While the bonding coat is tacky, pour a small quantity of mixed Durabond Floor Levelling Compound on the prepared surface and trowel tightly to a thin coating. Follow immediately with further coats, but no more than 6mm
Finishing
After initial hardening, usually with 3/4 - 1 hour, the surface may be sprinkled within water and trowelled tightly to produce a final smooth surface (do not apply too much water and avoid over-trowelling)
Caution
Do not mix more than can be laid in 20 minutes. The free-flowing properties of Durabond Floor Levelling Compound are reduced after 10 minutes and workability will be lost after 30 minutes. Never reconstitute the mix after initial stiffening has taken place. Do not work before 4°C. Always turn off under-floor heating and allow sub-floor to cool and do not switch it on again for at least 24 hours after completion. Do not allow to dry too quickly in hot weather.
Coverage
1.5 - 2kg per m² at a thickness of 1.5mm depending on surface.
Health & Safety
Care should be taken to avoid skin or eye contact. Wear gloves, safety glasses and overalls. Wash splashes immediately with soap and water. In case of eye contact, wash with copious amounts of clean water and seek medical attention.
