Industrial Floor preparation

Where a new concrete industrial floor has been laid, correct preparation is required to ready the surface for its new coating. In many instances, an old coating needs to be removed from an existing factory / warehouse floor and the underlying concrete substrate similarly processed. Sometime, more remedial work such as line marking / anti slip needs to be removed.

The type of coating that is being applied to the concrete surface determines the process used to prepare it. There are also economic factors – simply time costs money.

For this reason Captive Shot Blasting is one of the most common techniques employed in preparing factory floors. The captive process ensures that dust and debris is collected, whilst the type of shot, travel speed and size of machine can be regulated to maximise the speed and efficiency of the process. In high productive areas, it is essential to reduce the amount of downtime as much as possible to reduce costs, making this process highly desirable.

In cases where the underlying concrete substrate is so bad that a screed will need to be applied – shot blasting can remove the old surface and leave the heavy textured, aggressive profile required in one pass. Yet, with the skill and precision our shot blasting teams have, the lightest of coatings can also be removed.

In some cases, Diamond Grinding can be the preferred method of preparation required. This technique on average takes longer than captive shot blasting but has the advantage that the final surface profile can be refined to a very high degree of accuracy.

Roughness, faulting and high spots can all be removed effectively with diamond grinding without the risk of micro-fractures forming on the concrete substrate. This is vitally important when any thin coating is to be applied; the faults would be visible otherwise.

Some surface preparation contractors would ague that Diamond Grinding is the quickest of methods in removing epoxy surfaces in these situations. It should be remembered that in-fact PCD’s are used as to remove epoxy with grinding machines. These are cutters – not grinding blocks; If the right care and skill is not present in the operator, the underlying surface can easily be damaged and require repair.

There are indeed many cases where both techniques are employed – captive shot blasting to remove the surface and grinding to achieve the desired profile for the coating being applied. Sometimes, if a really aggressive approach is needed surface planing may be employed as a technique.
