Average rates for painting - Resene

Resene Professional development programmeRepainting concrete and cementitious surfacesis usually straightforward, any problems are selfevident(such as cracking and leaking). Spallingdue to reinforcing rusting needs a careful approach.Always on sheltered or Southern elevations concretewill have moss and mould to remove.Degraded and powdery surfaces must be sealedprior to repainting with Resene Sureseal pigmentedsealer, which both penetrates, binds and seals tosurface (brickworkHardiplanks are generally accepted as amongstthe easiest exterior items to repaint, but, inspectnailheads carefully, the galvanised flatheadssometimes need priming where the galvanisingis eroding. (Spot priming with Resene Armourzinc110 is ideal for this purpose.)Painters are frequently asked to apply ‘graffiti proof’clears over existing paint surfaces. Remember thata whole catalysed urethane system includes primer/topcoats (see specialist coatings).The textural differences generally become moreexpensive as the texture becomes greater because,on average, more material is applied. These ratesare indicative only and also are for decorativerather than protective coatings. Monolithic texturesas part of an exterior cladding system are notincluded.The rates or textures achieved with thixotropicmaterials (Resene Thixalon 5) or crushedaggregates (Resene Resitex E) are similar givenrelative textures..These rates are for decorative texture coatings andare not to be considered for monolithic texturedcoating systems. This is a specialised, licensedapplication – one of the downstream consequencesof the ‘leaky homes’ problems. See RockcoteSystems.45
