Application Instructions Preparation The substrate should be clean, sound and free from loose material and contamination such as plaster, oil, paint and grease. New concrete should be at least 14 days old. Excess laitance should be removed by light scabbling or captive shot blasting followed by vacuuming to remove dust debris. Oil and grease must be removed. Large cracks and holes may be filled using a mix consisting of equal volumes of Durafloor Leveltop and clean sharp sand made up to a trowellable mortar by the addition of a small amount of water. Prime the substrate with Durafloor Level Prime prior to repair. Priming The object of priming is to seal the substrate to prevent air release from the subfloor rising and forming bubbles and pinholes on the surface of the Durafloor Leveltop. Extremely porous substrates may require two priming/sealing coats. Primer coats must be allowed to dry before applying the Durafloor Leveltop. 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 if necessary, and allow to dry. For applications where water vapour, seepage or moisture are of concern, pre-treatment and priming with Emer-Proof Aqua Barrier is recommended. Contact Parchem for further advice. Application of Durafloor Leveltop over Emer- Proof Aqua Barrier Apply the first two (2) coats of Emer-Proof Aqua Barrier as per the TDS and allow to cure. When using Emer-Proof Aqua Barrier under Durafloor Leveltop, it is essential that a third coat of Emer-Proof Aqua Barrier is applied to act as a bonding coat. The bonding coat of Emer-Proof Aqua Barrier is to be applied at 5m²/L and Durafloor Leveltop must be applied whilst the bonding coat is still tacky. If the bonding coat has been allowed to cure to a tack free state, a further coat must be applied prior to application of Durafloor Leveltop. Installation Mixing Use 3.75 litres of cool, clean water per 15 kg bag of Durafloor Leveltop. Pour this water into a container, start mixing with a forced action mechanical mixer (or a purposemade paddle in a heavy duty drill), slowly add all the powder while mixing, mix evenly through material for 2 minutes until a smoothing fluid is achieved. Do not mix more than can be laid within the flow time of the material, but ensure that the subsequent mixes are ready to allow the necessary continuous pouring for the entire surface. Application Pour the mixed material onto the primed substrate trowel then allow to self-smooth. Use spiked rollers to give a final smooth finish. Do not attempt to float the setting surface, if high spots or splashes occur, these can be pared off with the edge of a trowel after the initial set. The required thickness must be achieved in a single application, by pouring and levelling in a continuous process until the designated area is completely levelled. If mix stiffens it must be discarded - do not attempt to remix with water. Air and substrate temperatures must be above 5°C during application and cure, and rapid drying conditions must be avoided, especially direct sunlight or through drafts, until the material is hard (2 - 4 hours). Installation by pump 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.
