Roof Painting - Priming And Painting A Roof

Before any roof painting project starts, the roof, which could be any kind of roof, namely a new roof, old roof, flat roof, metal roof, tile roof, corrugated iron roof, warehouse roof or tin roof, needs to be cleaned first and then primed before it is painted. Galvanized and aluminium metal requires special primers. Rusty metal roof surfaces need to be primed with a white latex metal primer or a rust reforming rust conversion liquid. There are specific ways in which a roof needs to be painted by you or a team of roof painters or painting contractors. As soon as the roof has been cleaned and primed the first coat of paint needs to be applied. In most instances this first coat of roof paint needs to be applied onto the surface of the roof at temperatures above fifty degrees Fahrenheit or ten degrees Centigrade.

The paint must be properly stirred before painting the roof with it. The first coat of paint can be applied to dry or slightly damp surfaces, using a hand painting brush, roller or air pressure spray. The paint must be painted on in generous amounts making sure that all pores and cracks are painted over and into. This coat of paint must be applied as smoothly as is practically possible. A minimum of two coats of paint is recommended. Two thin coats are always preferable to one thick coat of paint. Each coat should be applied perpendicular to the preceding coat of paint as this will create the desired effect of a checkerboard pattern. This method guarantees no thinly painted areas and ensures a more uniform finish.

Some paints do not require thinners to be added to them as they are at the correct consistency to paint onto the roof immediately. The painting contractors will know that if they apply thinners to a paint that requires no thinners it will reduce the percentage of solids, which will adversely affect the durability of the applied coat of paint. On a rough porous surface, such as concrete tile, four and a half litres of paint will usually cover an area anywhere from twenty five to thirty three square metres. On porous surfaces, the total area painted by the second coat of paint will usually be larger than the first coat of paint. On smooth, non porous surfaces, such as sheet metal, the area that can be expected to be covered, four and a half litres of paint, will be between thirty three and fifty square metres.
