Problem Solver - Softwood


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.


Stage 1 - Preparation

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

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

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.

Stage 2 - Basecoat

Apply a suitable wood primer

Apply an appropriate undercoat

Stage 3 - Topcoat

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