Sikkens Rubbol WP 151 sprayable 2K blocking primer for exterior joinery

Sikkens Rubbol WP 151 is a waterborne, white, two-pack, sprayable primer for Exterior and Interior wooden components such as Front Doors and Windows made with problematic wood species such as Larch, Pine and Hardwood. Primers are the connection between wooden surfaces and coatings. Their composition influences way the final coats perform, so it's vitally important to choose the correct primer for the job you are doing.

Sikkens Rubbol WP 151 is a white 2K sprayable waterbourne acrylic primer with isolating properties for Front Doors, MDF/HDF and Windows made with discolouring wood types like Pine, Larch and Accoya. 

This white isolating base coat for interior and exterior wooden components is easy to sand and reduces discolouration from knots and resinous areas. It has good pore wetting, superb filling and isolating properties.

It can be sprayed using an Airless Spray System or HVLP Spray Gun with a 2.5mm tip onto a variety of stable wooden components like Windows, Outer Doors, Conservatories and semi-stable wooden components like Rafters, Gates, Shutters and Garden Houses. It must be activated with Sikkens WH 830 Hardener and comes as a complete composite pack.


  • Ultimate isolating Primer for Knots and Resins
  • Optimised covering of edges
  • High Sandability
  • Ideal preparation for subsequent white or coloured Topcoats
  • Use on Airless Spray or 2.5mm HVLP Spray Gun

Here at AllFinishes we take health and safety seriously and recommend you use the correct protection for the job. Disregarding safety equipment can be damaging and result in long term health conditions. Please check out our Moldex range for high quality respirators and hearing protection.


The wood moisture content for the application of Sikkens coating systems should be between 12 % and 15 %.

The selected wood, the design and the applied layer thicknesses must comply with current technical standards.

All horizontal surfaces shall be bevelled by 15 ° and all edges shall be rounded with a radius of at least 2 mm.

Joints and open end grains must be sealed to prevent the ingress of water into the structure.

The substrates must be dry, free from dust and grease. The selection and application of the coating, especially the colour shade, is important, too.

Dark coatings in the exterior may lead to an elevated surface temperature (up to 80 °C).

To ensure correct adhesion of the following coating system, the paint system should not be sanded down to the substrate.

Please speak to one of our technical helpline representatives for advice.
