How Do I Paint Resinous Softwoods?
Resinous softwoods tend to to grow in cold or milder weather regions and are considered an ideal material due toheir excellent mechanical resistance. These types of woof are one of the most commonly used in carpentry and construction projects. The most popular are pine, fir and larch which all come with a problem called colour bleeding. This is an issue especially with knotty softwoods since the knots leak more resin, leaving a stain. Stopping this resin can be very challenging. Blocking primers such as Multistop for interior wood or Pinja Flex Isolator for exterior can and do help, but heat sealing can provide a more effective solution:
- Scrape away excess resin.
- Heat knots with heat gun and again scrape away excess resin.
- Once complete, wash down all oily surfaces with cellulose thinner, then rinse with clean water.
- Allow timber to settle
Once complete, prime with Ultra Primer.
