Preparation work is essential before paint is applied, and it is the single biggest factor in whether a paint job lasts five years or fails within one. Skipping sanding, filling or priming is the most common reason painted surfaces crack, peel or blister early.
What Does Proper Paint Preparation Involve?
• Cleaning surfaces to remove dirt, grease, mould and chalking paint
• Sanding glossy or damaged surfaces so new paint can grip
• Filling cracks, holes and gaps with the right filler for the substrate
• Priming bare timber, stains or repaired patches before topcoats go on
Why Does Skipping Prep Cause Paint to Fail?
Paint needs a clean, slightly textured, stable surface to bond to. Painting over chalking, dirty or glossy surfaces without prep means the topcoat is only holding onto loose material, not the substrate itself, so it lifts and peels far sooner than it should.
How Much of a Painting Job Is Actually Prep Work?
On most professional repaints, prep work, not the painting itself, takes up the largest share of time on site. A quote that skips straight to “two coats” without mentioning sanding, filling or priming is usually a sign of corners being cut.
What Happens If You Paint Over Old, Peeling Paint?
Painting directly over failing paint traps the problem underneath. The new coat may look fine for a few months, then lift away in the same patches as the old paint underneath it, because the bond was never solid to begin with.
How Long Does Proper Prep Actually Add to a Job?
Prep can add anywhere from a day to several days to a job, depending on how much sanding, filling and priming is needed. It’s time well spent, since a rushed one-day prep on a job that needed three is exactly how a repaint ends up failing within two years instead of lasting ten.
