ProJoint™ V35-UV™ – Black

A single part PU resin mortar system with 100% UV stability designed for sensitive and expensive stone

A very advanced system, ProJoint™ V35-UV™ is a simple to use solution to filling joints between paving slabs and setts. Specifically designed for pedestrian and vehicular areas up to 3.5 tonnes traffic loading where sensitive and expensive stone is used, meaning ProJoint™ V35-UV™ is the perfect partner for the most prestigious of projects.

The single component PU resin is mixed with the sand in the kit and applied to paving using either a brush or squeegee.  It offers a long processing time which makes it especially suited for paving with narrow joints and for use in hot weather.  Shower resistant, it forms a UV stable, strong, weed free, frost and pressure washer resistant joint.

Following application, it is expected that this product may highlight and enhance the natural surface colours and textures of the paving. This is only a temporary effect as weathering and foot traffic accelerate its disappearance. Typically the sheen that remains is even and thin and dissipates over a short period of time.

ProJoint V35-UV is not recommended for use with porcelain paving – please refer to the ProJoint Porcelain Primer and Grout product pages for more information.
