The latest in our How to Speak Vebro series — a whistle-stop tour through our simplified product and system naming structure — is DPM, WB & SBR. Without further ado, here they are in a little more detail…
DPM: Damp Proof Membrane
Damp proof membranes, as the name would suggest, provide a moisture barrier between substrates with a higher moisture-content allowing for the subsequent application of resin floor systems.
Using a hydrometer, applicators will determine the relative humidity of the concrete substrate to determine whether a standard primer or DPM is required. Anything above the 75%RH mark will require the latter.
WB: Water Based
A handful of our sealers are water based polyurethane coatings and are designed to be used with vebroflex comfort flooring systems.
Water based PU sealers tend to be quick to dry, reducing construction schedules compared with longer-drying products. Transparent water based sealers are often chosen because they don’t affect the colour of the body coat below.
SBR: Styrene Butadiene Rubber
Also known as emulsion styrene-butadiene rubber (E-SBR), this product was first developed in the 1930s by I.G. Farbenindustrie in Germany. It was created through an emulsion procedure that used polymerization as the means of producing a material that had a low reaction viscosity but had all the attributes of natural rubber. Styrene-butadiene rubber (SBR) is one of the most versatile copolymer rubber compounds. It consists of the organic compound styrene and the chemical budatiene, with the amount of budatiene usually being about three times more than the amount of styrene. SBR is a stable synthetic that is resistant to abrasion. It is used in a wide variety of products, such as construction product mortars and screeds, automobile tires, children’s toys, shoe soles and even chewing gum.
