Problem Solver - Pine
Problem
Pine is a softwood and may often have several knots which are resinous areas in timber, that 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 degrease and remove any residue.
Brewers recommends:
-
Bird Brand Methylated Spirit 500ML
- For thinning and cleaning of compatible products. Ideal for use with shellac-based primers, coatings and finishes.
Abrade with 100 grit abrasive paper to remove any loose or flaking areas and to create a key
Brewers recommends:
-
Flexovit Glasspaper Sheet Grade F2
- F2 - very fine hand sanding sheets, ideal for general purpose applications.
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.
