Section 5 - Application

SW 5.01 Suitability of Primers

All primers must be appropriate for the surface and for subsequent coats.

SW 5.10 Ferrous Metal Fixings

Any uncoated metal fixings etc must be primed/pre-treated with the appropriate Metal primer/pre-treatment prior to the application of any subsequent compatible coating.

SW 5.20 Coating of Prepared Metalwork

Prepared metalwork must be coated as soon as possible on the day of preparation and before the standard of preparation has deteriorated.

SW 5.21 Overcoating of Prepared Woodwork

Prepared woodwork must be coated as soon as possible on the day of preparation and before the standard of preparation has deteriorated.

SW 5.22 Application of Finishing Coat

No coatings shall be left in an exposed or unsuitable situation for an undue period before applying the finishing coat.

SW 5.30 Two Pack Epoxy Coatings

It is important to remember that water based epoxy coatings will take longer to 'hard cure' than solvent based epoxies. Particular care must be taken during winter months when temperature fluctuations will affect the minimum overcoat time. A drop in temperature from 20 Centigrade to 10 Centigrade will result in the overcoating being delayed from 16 hours to 72 hours. Optimum chemical and abrasion resistance will not be achieved until the final finishing coat is allowed to dry for a minimum of seven days. Optimum intercoat adhesion properties will only be achieved if subsequent coats are applied within seven days. Refer to product data sheets for more information.

SW 5.31 Acrylated Rubber Paints

Products using Acrylated Rubber resins may be applied over existing coatings provided they are in good condition and thoroughly hardened. Some coatings may soften or lift and it is therefore advisable to check this by small scale tests. If the existing coating softens or lifts or is in poor condition, it should be removed prior to decoration.
