- See that all the paint required for the primer, undercoat and finishing coat is from the same manufacturer obtained in sealed containers and opened in presence of authorities.
- See that surface is properly cleaned and stopped before priming coat is applied. Commercial plywood must have a filler coat before priming coat is applied.
- Where two or more coats are to be applied see that each coat is of a slightly different tint, starting with a lighter shade of the colour with which you are to finish. Insist on passing each coat when it is completed and record this fact in the works-passing-register. See that each undercoat is properly rubbed before the next coat is applied.
- Do not use thinner to dilute the paint unless you are satisfied that the paint supplied is thick. In such event thinner recommended by manufacturer should only be used and in the presence of Engineer-in-Charge.
- Insist on the use of proper brushes. Workmen prefer to use rag or cotton waste. This must not be permitted on any account.
- Never allow any painting to be done on damp surfaces.
- See that paint is always well stirred before and during use.
- See that the timber to be painted has not more than the optimum moisture content as determined by a moisture meter. Painting shall not be done when it is humid or there is dusty wind. Morning hours are generally more suitable.
- Knots in coniferous Wilcox which exude resin should either be removed and replaced or two coats of knotting solution consisting of 0.25 kg. of shellac in a litre of methylated spirit applied to the portions.
- After priming coat is dry but not too hard, fill with putty all cracks and nail holes.
- See that all inaccessible portion like the top and bottom of doors, windows and CSWs are painted in advance.
- See that floors, window and fittings on joinery are protected from paint. If required, clean all fittings and hardware with paint remover as the painting progresses. Paint once dried and set is difficult to remove.
- When plastic emulsion paint is specified, carefully study manufacturer's instructions and follow precisely. This is a new type of paint and is expensive and any mistake in its application would result in a bad surface.
- Check slackness of glass and verify that the standard specified is being used. See that the glass is free from air holes and other defects.
- See that panes are sprigged and back puttied and that brads and not tracks are used. Panes must be cleaned before the building is taken over.
- p) See that the putty is made to the correct specifications. The putty in case of steel joinery is of different composition. Ensure that only correct putty is used.
