Firstly, it is important to ensure that the concrete base is thoroughly cleaned to remove any dirt or debris that could interfere with the final result. Once this is done it is recommended that a bonding product is applied to the concrete to ensure maximum adhesion. This can be achieved by applying PVA, epoxy resin or SBR (styrene-butadiene rubber) according to the instructions on the product.

It is also important to use the right type of screed mix for your project. Depending on the area of the floor and its intended use a self-smoothing or bonded sand:cement screed may be used or a fine concrete screed, which reduces the potential for shrinkage, can be used up to 75mm.
After the bonding agent has been applied and the concrete base has been cleaned, a primer should be applied to the surface of the concrete or sand: cement screed. This is usually sand: cement or cementitious screed primer such as Easy Mix Prime & Bind and must be mixed into the screed mix to ensure it is thoroughly combined. The next step is to divide the floor into sections with timber battens and apply the screed in stages, leveling it with a straight edge as you go. After the screed is laid it must be left to dry for a week before normal site traffic can resume and partition walls can be erected.
