Every surface and material has different physical properties and these properties can affect the way in which a coating performs.
All too often, we forget toi consider the type of substrate and apply our normal paint, then wonder why it has 'fallen off', 'discoloured' or damaged the surface.
Understanding the substrate properties and getting the preparation right will ensure you will get a successful job.
Some substrates like galvanised steel and aluminium need pre-treatment solutions or caotings to aid adhesion of subsequent coats.
Masonry can have some residual moisture and is also alkaline. Where the substrate is not completely dry, rhen a microporous coating needs to be used to allow the moisture a means of escape, without pushing off the coating.
New concrete is alkaline and also forms a chrystaline laitence of the newly laid surface. This laitence will powder and must be removed by blast cleaning or acid etch treatment. The coatings must also be alkali resistant.
Wood also hold some moisture and is continually expanding and contracting due to temperature anmd humidity. The coatings for wood need to flexible.
We have listed a few substrates on the left and suggest some suitable coatings for each substrate type. The product technical data sheets are available in our data sheet section.
