Our Exterior Painting Process
Our “SIX STEPS” to Spray Painting: Quality and Attention to Detail is at the Heart of our Process
1. Preparation
At PREX, every project begins with meticulous preparation.
We make sure that the paint adheres perfectly to the surfaces by washing them down with water and high pressure (when required). This step removes dirt, grease and old paint debris, especially on aluminum siding. We leave nothing to chance to ensure a flawless base.
2. Inspection
A thorough inspection follows preparation.
We identify walls in need of minor repair, and check caulking for cracks around doors. If adjustments are required, we note them and intervene accordingly. We also take care to carefully remove all exterior accessories (ventilation grilles, light fittings, mailboxes, civic numbers), ensuring total access and an uncompromising finish.
3. Masking
Surface protection is a key factor.
Afin de préserver l’intégrité de votre propriété, nous masquons minutieusement les ouvertures (portes, fenêtres) ainsi que les bardeaux de toiture, les fondations et les appareils d’éclairage permanents. Notre rigueur garantit des délimitations nettes et précises.
