term equilibrium moisture value or regular curing standards.

For these tasks, STAUF, a leading system supplier for flooring technology, offers a comprehensive system of primers which allows floor construction on graded residual moisture contents, differentiated according to technological basis and custom-tailored to levelling compounds.

For any floor construction, primers are the key components as they must ensure adhesion on a variety of different substrates, for which specifications are often vague or non-existent. At the same time, they must serve as bonding agents, not only for subfloors, but also in the other direction for levelling compounds or different adhesive systems. A good primer’s ability to form a layer that reduces and controls the water

vapour diffusion rate of the substrate (DPM) is also a function which becomes increasingly important. Ever shorter construction deadlines, the multitude of cement types used in cement screeds, the large variety of screed additives and the increase in direct installation of coverings on concrete floors, require solutions for floor construction even when the moisture content of the substrate exceeds the long-


STAUF VDP-160 This is a layer-forming dispersion primer which is to be applied with trowel or roller for use below nearly all STAUF adhesives and levelling compounds. It can also be used as bonding agent for levelling on DPMs which otherwise cannot be levelled directly, saving time and labour-intensive sanding of epoxy resin primers.

STAUF VPU-155 A layer-forming PU primer to be applied with trowel or roller for use below STAUF SMP-, SPU- and PUK adhesives. It increases hardness of screed surface and bonding can be performed after just one

hour. When used in combination with STAUF VDP-160, it can also be used below STAUF levelling compounds and DPM up to 3.0 CM-% (cement screeds only).

STAUF VEP-190 This product is a layer- forming 2c epoxy resin primer to be applied with trowel or roller for use below STAUF SMP-, SPU- und PUK adhesives and below STAUF levelling compounds. It increases the hardness of the screed surfaces and DPM up to 5.0 CM-% on concrete substrates by up to 6% by weight. It acts as a bonding agent on non-absorbent, smooth substrates, bonding directly with STAUF SMP-, SPU- und PUK adhesives within as little as 24 hours. It can be used below STAUF levelling compounds when sanded or, alternatively, it can be levelled without prior sanding when using STAUF VDP-160 as bonding agent
