Before painting, prep your roller by washing it out making it easier to load paint. With your brush soak it in an inch of water for 10 mins. Ensure you shake out excess moisture.
In between paint coats or short breaks, avoid washing your roller/brush, instead, wrap it with cling wrap to keep it fresh.
For paint trays, buckets and pots wrap with aluminium foil.
Use roller cleaner or brush comb to remove any excess paint from your roller/brush.
Wash your roller/brush with Soapy Luke warm water.
Once dried, store your rollers/brushes in dry and out of weather place. You can store your brushes in the brush keeper while the rollers can be stored in a ziplock poly bag or roller canister.
