Good painting decisions begin before the first bucket is opened. Use this guide as a practical starting point, then confirm the details of your own building before purchasing or beginning work.
Do not coat wet walls
Exterior surfaces should be suitably dry before painting. Rain just before application can leave moisture in porous walls.
Watch the forecast and drying window
The risk is not only rain during painting; rain shortly after application can also damage uncured exterior coatings.
Manage indoor humidity
Interior work may continue, but ventilation and drying can be slower during humid periods. Allow adequate time between coats.
Prioritise sheltered and interior areas
On uncertain weather days, organise work so sheltered, internal or preparation tasks can continue without risking fresh exterior coats.
Practical next step
Every building is different. Share your location, wall condition and project type with Filadephia Paints so the product, quantity and preparation advice can be matched to your actual job.
