Features and Benefits
-Quick setting, high strength
-Easily applied. 
-Mixed only with water. 
-Self levelling. 
-Pumpable.

Application Procedure
Preparation of Substrate
The surface should be firm, free of dust, dry, clean and strong enough to support the weight. Any oil, grease, rust, gypsum, wax, paint residues, loose particles on the surface should be removed. The joints, cracks etc. should be repaired prior to the application. In large areas, application levels should be determined by gridding.

Priming
In order to prolong the working time of PoliFloor®65-CS levelling compound, to enhance the adherence to the floor and to minimize air bubbles;
-Universal Prime is applied with a brush or a roller. On very absorbent surfaces a second layer is applied. 
-After the drying test, other operations can proceed. 

-In extremely cold conditions, heaters should be used to increase the ambient and surface temperature; and in order to increase the workability of the product, the packages should be preconditioned to +20˚C-+25˚C to become ready to use. 
-The applications should be carried out by suitably qualified applicators. 
-The working and reaction times of the cementitious systems are affected by the ambient and surface temperature and relative humidity in the air. Hydration slows in lower temperatures and this increases pot life and working time. Higher temperatures increase the hydration and the above mentioned times decreases accordingly. In order for the material to complete setting, the ambient and surface temperature should not drop below the allowed minimum temperature. 
-The compound should be allowed to rest after mixing, and then mixed again prior to application. 
-At least 3 days should pass for any other work (wooden parquet, vinyl etc.) after PoliFloor®65-CS application.
-Fast drying should be prevented after the product is applied. The applied material should be avoided from the contact of water.

Mixing
A correct amount of water is poured into a clean mixing bucket using a measuring cup. PoliFloor®65-CS is added gradually and the mixture is mixed with a 400-600 rpm mixing equipment for 3-5 minutes until a homogenous, lump free mixture is achieved. The mixture is allowed to rest 3-5 minutes, and after mixing for 30 seconds the product is ready to use.

Mixixng Ratio

Application
The mixture should be spread on the surface with a toothed trowel or an adjustable trowel at the required thickness. The compound spreads evenly by self levelling. Do not add water during the setting and release any entrapped air in the surface with a spiked roller. PoliFloor®65-CS shouldn’t be applied at temperatures below +5˚C and sudden fluctuations in the temperature should be prevented. The application shouldn’t be carried out in areas with low humidity, higher ambient temperatures, and in areas which are exposed to sun and wind.

Coverage
1.6 kg/m2 powder per 1 mm thickness

Watch Points
-If the ambient and surface temperatures are less than +5˚C and more than +25˚C, suitable temperatures should be waited for the application. 
-Furthermore, the product shouldn’t be applied at extremely hot, wet or windy weathers. 
-The materials to be used at the appropriate temperatures should be brought and stored in the application area 1-2 days prior to the application and enabled to adjust the ambient conditions. 

Cleaning of Tools
Tools and equipment should be cleaned with water after the application. Hardened PoliFloor®65-CS can only be removed from the surface mechanically.

Packaging
In 25 kg polyethylene reinforced kraft bags

Storage
The product should be stored in its original package, in a cool and dry place protected from frost. For short term storage, maximum 3 palettes should be placed on top of each other and the shipment should be made on a ‘first come, first go’ basis. Palettes should not be placed on top of each other during long term storage.

Shelf Life
The shelf life is 12 months from the date of production under suitable storage conditions. Opened packages should be stored under suitable storage conditions and used within 1 week.
