Technical data

Raw material base: Polyurethane resins

Drying time: approx. 40 - 50 minutesat least 2 hours for layers treated with quartz

Cleaning agent: WAKOL RT 5960 Cleaning Cloth before primer dries

Storage time: 12 months in the sealed container

Storage temperature: not below +5 °C, sensitive to frost

Application and consumption:
WAKOL Primer Roller, 11 mm Velour or Foam roller / 100 - 150 g/m² / As a primer when only one layer is applied
WAKOL Primer Roller, 11 mm Velour or Foam roller /  250 - 350 g/m² / As a moisture barrier when two to three layers are appled

Ready-to-use 1-component polyurethane primer for priming absorbent and non-absorbent subfloors, and to reinforce abraded resp. sanded concrete edges. Also for capillary ascending humidity and higher residual humidity up to 6 CM% / 98 corresponding RH % in cement screeds without floor heating, on heated cement screeds up to max. 3 CM% / 85 corresponding RH % as well as on concrete up to max. 7,5% by weight / 98 corresponding RH %; applicable as moisture barrier on unheated cement screeds and concretes without prior moisture measurement.

Shake the container well before using. Apply the primer with a WAKOL Primer Roller, velour or foam roller, without letting the substance pool. If using as a moisture barrier, WAKOL PU 280 Polyurethane Primer must be applied in two layers using a criss-cross method. Each layer must form a thin closed film. The direct bonding work should be completed after the primer has dried and within a 72-hour period, or alternatively a bonding course should be applied using WAKOL D 3045 Special Primer and the surface should be levelled using a Wakol levelling compound within 24 hours. For more information, please consult our Application Technology department. As an alternative to using the special primer, a third coat of WAKOL PU 280 Polyurethane Primer can be applied and WAKOL S 28 Sprinkling Sand subsequently spread on the surface.

After the primer has been left to fdry for at least 2 hours, any excess quartz and should be swept
off and vacuumed up.

Levelling can be carried out using Wakol levelling compounds once the surface is completely set. Primed surfaces can be walked on after approximately 40 - 50 min. Within 72 hours, bonding work can be carried out directly on the dried WAKOL PU 280 Polyurethane Primer using Wakol MS or PU adhesives.


Processing not below floor temperature of +15 °C and room temperature of +18 °C, as well as room humidity preferably between 40 % and 65 %, maximum 75 %. All information is based on approx. 20 °C and 50 % relative air humidity. Warm up all laying materials in due time in heated room.

Do not use the primer on floor coverings such as PVC, CV, rubber or linoleum flooring.

If the humidity is low or higher application quantities are used, this extends the drying time
of the reaction resin primer. The surface must no longer be adhesive before work can be continued.

We guarantee the uniform high quality of our products. All data is based on tests and many years of practical experience and refers to standardised conditions. The variety of materials used and the different construction site conditions, which lie beyond our control, preclude any claims based on this data. We therefore recommend making sufficient trials. Accompanying flooring manufacturer's instructions and the currently applicable codes must be observed. We gladly provide technical advice.
