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.


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.
