Section 3 Coatings and paint systems

3.1.1 The painting specification as well as specifications for preparation, application and curing are to be submitted for approval.

3.1.2 Paints, varnishes and similar preparations having nitrocellulose or other highly flammable bases are not to be used in accommodation or machinery spaces or in other areas with an equal or higher fire-risk. Particular regard is to be paid to the possible effects in an oxygen enriched atmosphere.

3.1.3 Where a coating is to be applied in accommodation spaces, machinery spaces and areas of similar fire-risk, the coating is to have low flame spread characteristics.

3.1.4 Paint or other similar coatings containing aluminium should not be used in positions where flammable vapours may accumulate, unless it has been shown by appropriate tests that the paint to be used does not increase the incendive sparking hazard.

3.1.5 Paints or other coatings are to be suitable for the intended purpose in the locations where they are to be used, unless previously agreed, at least two coats are to be applied.

3.1.6 Coatings are to be applied to blast cleaned surfaces prepared to at least an equivalent of Sa 2,5 of the Swedish Standard SIS 055900. All resulting dust is to be removed from the surface prior to the application of any paint.

3.2.1 Where a primer is used to coat steel after surface preparation and prior to fabrication, the composition of the coating is to be such that it will have no significant deleterious effect on subsequent welding work and that it is compatible with the paints or other coatings subsequently applied. Approved coatings are listed in LR publication Approved Prefabrication Primers and Corrosion Control Coatings.

3.2.2 The tests are to be carried out in the presence of a Surveyor to LR or by an independent laboratory specializing in such work, a copy of the test report is to be submitted, together with radiographs and macrographs.
