Dingo Self-Levelling Cement is a cement based, self-levelling underlayment. It is high strength and is designed for levelling internal and external floors.

Dingo Self-Levelling Cement has properties similar to concrete and it can be feathered to a 2mm edge. Using clean water Dingo Self-Levelling Cement will reach a very fluid consistency, that will leave the surface level, smooth and hard. For thicker applications, Dingo Self-Levelling Cement can be applied in layers with each layer being no more than 25mm thick.

This product can be used in both domestic and commercial applications and can be used on floors internally and externally. Whilst this product is suitable for use in wet areas, it should not be used in areas that will be constantly under water. Dingo Self-Levelling Cement can be used prior to installing floor tiles and carpet and is able to be used with tile and contact adhesives. Allow 24 hours before applying a floor covering.

Dingo Self-Levelling Cement is not to be used as a final flooring finish.

Before you start

  • A test should be performed in all cases to ensure suitability of this product.
  • Do not use when temperatures are below 5°C or above 35°C.
  • Do not apply if temperatures are expected to reach these levels within 24 hours of application.
  • Do not use Dingo Self-Levelling Cement in applications where the product will be constantly under water

Surface Preparation

  • Surfaces must be structurally sound and clean. Ensure the surface is free of all contaminants including dirt, dust, oil, grease, latex compounds, glue, paint, gypsum-based products etc.
  • Contaminated substrates must be ground back to a clean surface.
  • Any large cracks and holes should be patched with a suitable concrete repair mortar before using Dingo Self-Levelling Cement.
  • Construction joints in the sub-floor should be carried through the self levelling cement to avoid cracking.
  • All concrete sub-floors must be fully cured and dry and have a wood float finish.
  • If the sub-floor has a high moisture content or subject to rising damp, apply an epoxy moisture barrier.
  • Non-porous surfaces must be primed with an epoxy moisture barrier, or acid etched, or mechanically abraded to ensure the Self-Leveling cement has a rough surface to bond to.
  • It is essential to prime the surface with a suitable primer before applying Dingo Self-Levelling Cement. This will improve adhesion and greatly reduce pin holing in the finished floor.
  • Where the temperature is above 28ºC, it is crucial to wet down any concrete slabs with clean water before priming. Before applying the primer, ensure the floor has no pools of water and has a low sheen appearance.

Mix Process

1. Dingo Self-Levelling Cement must be mixed using a heavy-duty electric drill and paddle attachment. This will ensure you have a smooth mix. Do not use a concrete mixer or mix by hand. These are not suitable mixing methods.
2. Add approximately 4.2L to 4.6L of clean water to a clean bucket and then slowly add the 20kg bag of Dingo Self Levelling Cement. Less water may be required for colder temperatures.
3. Mix for at least 2 minutes and continue to mix until you have a smooth, lump free consistency.
4. Mixing drill should be set to maximum 600rpm.

Note: If foaming and streakiness appear on top of the mixture, Dingo Self Levelling Cement is over-watered, and should not be placed on the substrate. More powder may be added immediately whilst mixing to achieve proper consistency.
Do not mix more material than can be used in 10 to 15 minutes.

High Stress Areas
When being used in high stress areas, (for example over heated sub floors or in wet areas) Dingo Self Levelling Cement must be used with an acrylic additive. Generally, this is 1 part acrylic additive to 2 parts water, however follow the directions on the acrylic additive packaging. Add approximately 5L of this mix to a 20kg bag.

Large Areas
Large areas requiring fills between 25 -100mm, use MaxPRO Concrete Mix or Dingo Hi Strength Concrete Mix. If using Dingo Hi Strength Concrete Mix add reinforcing steel if fill is more than 25mm. Ensure you attach the new concrete to the old concrete using pins.

Pumping
If pumping mix in an appropriate pre-pump mixer. Do not mix more material than can be used in 10-15 minutes. Mix speeds must not be too high, otherwise it will cause aeration. Clean mixers and pumps thoroughly after each batch to avoid material build up.

 

Application

  • Pour Dingo Self-Levelling Cement on to the primed surface. 
  • Move it into approximate position with a long-handled squeegee and allow the material to find its own level. 
  • Dingo Self-Levelling Cement must cure 24 hours at 20°C before any floor coverings are installed. 
  • Dingo Self-Levelling Cement may be layered up to 25mm. An additional layer may be applied directly over the surface as soon as it will support foot traffic – approximately 4 hours. 
  • When using Dingo Self-Levelling Cement outside, ensure the product is protected from direct sunlight and high winds to prevent the product losing moisture too quickly. 
  • Dingo Self-Levelling Cement should not be overwatered, over-mixed or remixed with additional water. 
  • Any material over 20 minutes old should not be used and should be disposed of. 
  • Do not use Dingo Self-Levelling Cement over a slab with a high moisture content or that is subject to rising damp unless a suitable epoxy barrier is used prior.
