This study guide brings together the most important concepts and connections in the painter trade. Use it as an overview when you revise for school or prepare for your apprenticeship.
The craft's two purposes
Painting always has two sides: protecting the material against moisture, sun and wear — and giving the surface the appearance the customer wants. When you assess a job, think about both.
Pre-treatment is the core
01Assess the substrate: material previous treatment moisture and damage
02Clean for dust, grease and loose particles
03Fix cracks and holes sand smooth and vacuum
04Base absorbent and new substrates so they become uniform
Application and layer
Paint edges and corners with brush, surfaces with roller, and large/smooth areas with spray. Apply paint in thin, even coats with sufficient drying time between — several thin coats always beat one thick one.
Materials to know
01Water-based vs. solvent-based (alkyd) paint
02Gloss value: flat, silk, high gloss — choose according to room and use
03Primer and top paint from the same system where possible
Safety to remember
01Work at height: choose scaffolding over wobbly ladder
02Respiratory protection when grinding and spraying, gloves against chemicals
03Read the safety data sheet before using new products
04Think about the indoor climate for those who will use the room
