Blackfriar Exterior Varnish – Durable Protection for Wood & Joinery

Blackfriar Exterior Varnish enhances and protects all types of timber and external joinery. When applied over Blackfriar UV Wood Primer, it resists UV light, weathering, and daily wear, providing long-lasting durability while maintaining a natural wood finish.

Ideal for bare or stripped wood, this solvent-based varnish is tough yet flexible, protecting your outdoor timber from cracking, peeling, and fading. Its high-quality formula ensures beautiful, resilient results for windows, doors, fences, and other exterior woodwork.

Key Features:

UV Protection – Absorbs ultraviolet light to prevent fading
Weather Resistant – Suitable for all exterior wood surfaces
For Bare or Stripped Wood – Versatile application
Tough & Flexible – Prevents cracking and peeling
Solvent-Based Formula – Durable, long-lasting protection

Surface Preparation

Timber must be clean, dry. smooth and free from any surface contamination such as oils, grease, loose or flaking varnish and denatured timber that may affect the performance of the Blackfriar Exterior Varnish. Remove excess resin from knots and clean with methylated spirit. Due to its orange/brown colour Blackfriar Patent Knotting should not be used under the Blackfriar Exterior Varnish. Oily woods, such as teak or iroko, should be thoroughly cleaned with a cloth impregnated with white spirit to remove natural oils. Non-ferrous nails are recommended
for fixing beading etc. Remove old varnish completely with Blackfriar Professional Paint and Varnish Remover, and then treat as new timber: Any French Polishes must also
be completely removed.

Testimonials

★★★★★
I stumbled across Andrews Coating Services as i was moaning about having spent laids on Everest (waste of a LOT of money) Concrete driveway paint and sealant only for petals to stick to it in rain, fade really badly, and peal away after 18 mths.
I spoke to Matt initially and explained my predicament and what i wanted to achieve with the paint and its application, his knowledge is second to none and having qualified my needs unlike the generic paint suppliers his can do attitude and understanding and quick turnaround made me visit him and place orders, the fact that you can choose pit of 70k+ colours is great but the fact that they just don't do domestic paints they also do specilaist paints such as hygienic wipe down and commercial and a vast array of other types too...

I can't fault the service and courtesy of this firm. The order was delivered as promised, and when a slight issue arose, it was corrected without question and quickly. I would use this firm repeatedly, and it is refreshing to find such good service nowadays. Also, they stocked the specialist products I wanted, when many were unable to supply. I am a customer for life.
