Quality Description

Clearance packs are made up of boards pulled out during the production process because they do not make the grade for one reason or another.

The severity of the defects varies from minor damage, dirt, marks, knot holes, staining to longer splits and damaged sections that will require trimming out. Clearance packs contain boards with some or all these defects.

Our grading system indicates the approximate quality you should expect.

Grade 1: Contains excellent material with occasional minor defects.

Grade 2: Contains a moderate number of defects.

Grade 3: Contains boards that are very dirty with a significant number of defects but still plenty of recoverable material.

If you don’t have the correct tools and are unable to put work in to recover the wood we’d advise you to go for a higher grade pack.

Further Information and Tips

Please note that some of the photographs may not be of boards in this specific pack. We’ve included a series of photos showing typical defects found in the clearance packs.


  • Sand out any marks/stains with a random orbital sander using 60 / 80 grit sanding discs.
  • Trim out larger defects using a crosscut saw.
  • Rip damaged pieces with a circular saw or table saw to make smaller sections (trim etc).
  • Optimise material by planning the positioning of boards and any cuts to be made beforehand.
  • Use the least attractive pieces in less visible areas, e.g., round the back of a building.
  • Use an exterior wood filler in knotholes.
  • Apply a coating such as Sansin SDF. Opaque colours will obscure most defects.

Clearance packs are sold at heavily reduced prices on the understanding that you purchase the full pack as is. They are sold as seen, and we are unable to exchange individual boards for any reason.  

This pack is available for collection from Widnes or Harmondsworth, or for delivery in our local areas (North or South).
