WG-50 Fast Setting Self-Levelling Screed 20kg Cekol

USE
CEKOL WG-50 is used to level up a floor or create a subfloor, perfect to follow with ceramic and stone tiles, PVC covering, textiles, panels, wooden floors etc. It can be applied only indoors on stabilised and dry mineral surfaces, in rooms with relative humidity up to 70%.

CHARACTERISTICS
CEKOL WG-50 is a dry mixture of synthetic gypsum, mineral fillers and modifying additives. CEKOL WG-50 mortar can be applied in the layers of thickness of 3 to 50 mm, as a composite screed on a separating layer or as a floating base. The mortar can also be used in floor heating systems applications.

• Mixing ratio: approx. 7 l of water per 20 kg od powder
• Pot life: around 30 mins
• Walking on: after min. 3h with temp. min. 18C
• Drying time: around 1,5 mm of thickness per 24h
• Consumption: round 15 kg/m²/10 mm
• Layer thickness: from 3 to 50 mm
• Carpets, laminate flooring and tiles should be fitted when the compound is fully dry (humidity below <1%).
• Application temperature: +5˚C to +25˚C

SUBSTRATE PREPARATION
The substrate should be clean, compact, carrying and free of grease. Before covering, the base must be stabilized and dry. The substrate’s stiffness should be greater than 1,5 MPa. Prime the substrate twice before pouring the screed. The screed should be separated from walls and expansion joints existing in the substrate should be moved to the surface after binding. The maximum single surface without internal expansion joints is 50 m². In the case of very weak substrates, CEKOL WG-50 screed should be made on a separating layer. It could be for example polyethylene foil with min. thickness of. 0,1 mm or other material with similar characteristics.

EXECUTION
Pour the contents of the package into the water in a proportion of about 7 litres of water per 20 kg of dry powder and mix until a uniform mixture is obtained. After 5 min. mix the mortar thoroughly again. In the case of mechanical pouring, find the right amount of water to reach the desired consistency. The mortar should be used within 30 minutes from mixing. Cover the ready substrate with the liquid mortar and level with a trowel or a patch and vent with a spiked roller, brush or rake. After pouring, the fresh mortar must be protected from direct sunlight and sufficient ventilation in the room must be provided. If you notice a deposit on the surface of the screed it should be removed by sanding it down. It will speed up the curing process.

STORAGE
Keep in the original packaging in a dry and dark place, away from sources of heat. Protect from excessive temperature and frost.

NOTES
1. Min. thickness when pouring on top of a floor insulation is 35 mm
2. Min. thickness when pouring as an independent layer is 35 mm.
3. Layer thickness above heating element min. 10 mm.
4. When pouring over underfloor heating, the system should be turned off during the whole process. Turning on after min. 7 days.
5. Carpets, laminate flooring and tiles should be fitted when the compound is fully dry (humidity below 1%).
