Product Description

Transform interior woodwork with Blackfriar Polyurethane Varnish. This tough and durable varnish brings out the natural grain and colours of wooden surfaces – and protects them from household stains including hot water.

Performance Characteristics

  • For all types of interior wood
  • Tough and durable
  • Resists hot water splashes
  • Resists dilute acids
  • Solvent based

Preparation

Ensure surface to be varnished is clean, dry, sound and free from wax, oil or any other contamination. If wax has been used clean the surface thoroughly with white spirit prior to sanding. Bare wood should be sanded to a smooth surface, always working with the grain. Sound previously varnished surfaces should be lightly sanded to provide a key. Remove dust. Existing varnished surfaces which are unsound or in poor condition can be stripped back to bare timber with Blackfriar Professional Paint and Varnish Remover.

Application

Stir thoroughly with a broad stirrer prior to use. The product may be applied by brush or roller. If applying by brush, apply evenly using light strokes following the grain of the wood. If rollering, use a short nap mohair roller. For best results 3-4 coats are recommended on new wood and 2-3 coats on previously varnished surfaces. Prior to application of the final coat or if the overcoating time is exceeded lightly abrade with fine glass paper working with the grain and remove dust.

Limitations

  • Do not use over French polish.
  • The matt finish is not suitable for use on floors.
  • Not suitable for use on plastic type materials, eg. imitation wood.
  • If using a coloured finish: Apply the material as evenly as possible to maintain an overall consistent colour.
  • The final shade of the varnish depends upon the original colour and the absorption of the timber we recommend to test for shade on an off-cut or inconspicuous area.
  • If using two tins we recommend mixing them to ensure an even shade is obtained.
  • Before applying varnish to floors we recommend a trial application on an inconspicuous area of the floor. Once dried check adhesion with a sticky tape. This is essential, particularly when applying to cork tiles, pre-finished tiles or laminate flooring.

Drying Times

Touch dry in 2 - 4 hours. Recoat after 16 hours and within 3 days.

Drying times are based on an ambient temperature of 20°C and 50% relative humidity. Lower temperatures or higher humidity will prolong the drying and overcoating times.

Question: Can I apply this varnish successfully onto a surface already treated (3 thin coats) with Black Friar Quick Drying Varnish?

questions Sheila Marshall on 17/10/2016
Question: Can I successfully mix two colours of the Blackfriars Polyurethane varnish?
Answer: 

This should be OK, the colours will be compatible with each other but always best to try a small test first to check the ratios to get the best colour.
