Problem Solver - Softwood

Problem

Softwood are fast grown timbers which can often be used in construction. They may often have several knots which are resinous and if left unsealed can bleed through paintwork leaving unsightly marks.


Stages

Stage 1 - Preparation

Using a hot air gun, remove as much excess resin as possible.

Brewers recommends:

Using a cloth, apply Methylated spirits to the knot and surrounding area to de-grease and remove any residue.


Abrade with 100 grit abrasive paper to remove any loose or flaking areas and to create a key

Brewers recommends:

If surface requires filling where repairs have been carried out use a two- part filler suitable for timber


Treat the knot with a knotting solution – using a brush, apply a thin coat, proud of the surface. Once dry, apply a 2nd coat.

Brewers recommends:
  • Mylands Patent Knotting 250ML
    - Fast drying shellac sealer for knots in resinous timbers. Seals affected areas prior to painting. Prevents long term discolouration. Dries to a pale brown colour.

Stage 2 - Basecoat

Apply a suitable wood primer


Apply an appropriate undercoat

Brewers recommends:
  • Albany Undercoat White 1L
    - Excellent covering power, finish for interior and exterior use on wood and metal. Perfect for new work and redecoration.

Stage 3 - Topcoat

Apply an appropriate topcoat and allow to dry, followed by a 2nd coat to finish.
