Linseed oil putty

Traditional putty contains a mixture of linseed oil and inorganic fillers (BS 544: 1969), which sets by a combination of aerial oxidation of the oil and some absorption into the timber. A skin is produced initially, but the mass ultimately sets to a semi-rigid material. Application is with a putty knife onto primed timber. For application to steel window frames, non-absorbent hardwoods and water-repellent preservative treated softwoods, non-linseed oil putty is appropriate. Linseed oil putty should be painted within two weeks, whereas metal casement putty may be left three months before painting.
