A beautiful paint finish begins long before the first coat of colour is applied. Proper preparation involves carefully assessing each surface and selecting the most appropriate method for its condition and material. Depending on the project, this may include washing, scraping loose or failing paint, sanding, filling cracks and imperfections, repairing damaged areas, treating mould or stains and sealing gaps. Just as importantly, there is no single primer suitable for every surface.
Professional preparation may require specialised sealer-undercoats for porous surfaces, stain-blocking primers, adhesion primers, timber primers, masonry sealers or corrosion-resistant metal primers. Selecting the correct preparation method and primer helps create a sound, stable surface for the paint system to bond to, improving both the appearance and long-term durability of the finished work.

Exposed timber and weathered coatings should be assessed before repainting. The preparation and primer need to suit the surface, and exterior coats should be applied in conditions allowed by the selected product. This guide explains preparation; for our local service, visit house painters Winmalee.
