Extremely porous substrates may require two priming/sealing coats. If two primer coats are required, the second coat must be allowed to dry before applying the Durafloor Levelbase. Installation by pump This is a specialised activity and the product must be applied by a Parchem recommended contractor who has been fully trained in the use of the product and equipment. Application procedure is as follows „ Thoroughly prepare the floor surface. „ Prime the surface with Durafloor Level Prime, broken down with 4 parts water to 1 part Durafloor Level Prime (by volume) and allow to dry. „ Reprime the surface with Durafloor Level Prime if necessary, and allow to dry. „ Apply Durafloor Levelbase to the required thickness onto the dry, primed surface. Installation by hand Mixing „ Each 20 kg bag of Durafloor Levelbase requires the addition of 4.2 - 4.5 litres of clean, cool water to produce a free flowing self smoothing consistency. „ Pour the mixing water into the clean mixing vessel. Add the powder slowly to the water, mixing continuously with a heavy duty drill fitted with a suitable paddle. Mixing should continue for at least 3 to 4 minutes until a smooth creamy consistency is obtained. „ Do not mix more Durafloor Levelbase than can be reasonably laid within the flow time of the material. However, ensure that subsequent mixes are ready to enable continuous pouring until the area to be surfaced is complete. Application procedure is as follows „ Thoroughly prepare the floor surface. „ Prime the surface with Durafloor Level Prime, broken down with 4 parts water to 1 part Durafloor Level Prime and allow to dry (Fosroc Nitobond AR may also be used). „ Reprime the surface with Durafloor Level Prime if necessary, and allow to dry. „ Pour the mixed material on to the dry primed surface, spread with trowel and allow to self-smooth. Best results are achieved when the pouring and levelling is a continuous process. Note: If the mix stiffens it should be discarded, do not attempt to re-mix with water. Bulking Out Durafloor Levelbase can be bulked out if necessary, however, this will reduce the flow characteristics of the mix. Up to 10 kg of clean dry washed sand/aggregate can be added to each 20 kg of Durafloor Levelbase. Sand/aggregate size should be in the range 1 mm to 5 mm with the maximum aggregate size being no larger than one third the minimum thickness layer being applied. Water addition must stay at 4.2 to 4.5 litres per 20 kg of Durafloor Levelbase (30 kg blended with aggregate). Cleaning Durafloor Levelbase and Durafloor Level Prime should be removed from tools and equipment with clean water immediately after use. Hardened material can only be removed mechanically. Limitations Although Durafloor Levelbase has a 28 day compressive strength of 30 MPa, it is designed as a sub-base material only and NOT as the final surface. Durafloor Levelbase must not be used in areas subject to permanent wetting or where rising damp is likely. To prevent rapid drying protect from direct sunlight and/or drying winds during application and the final curing period. If the surface onto which Durafloor Levelbase is applied moves or cracks, reflective cracking may occur. Note: Water addition outside the recommended levels as stated in this Technical Data Sheet will cause excess water to bleed from the mix causing potential delamination of any topping material. Estimating Supply 430095 - Durafloor Levelbase: 20 kg bag 480005 - Durafloor Level Prime: 1 litre 480016 - Durafloor Level Prime: 5 litre 480017 - Durafloor Level Prime: 20 litre Coverage Durafloor Levelbase: Each 20 kg bag yields approx. 12.25 litres when mixed with 4.5 litres of water Durafloor Level Prime: 10 - 20 m²/litre The coverage figures given are theoretical - due to wastage factors and the variety and nature of possible substrates, practical coverage figures will be reduced.
