Good to see that the concept exists, perhaps one day for 10L cans. The reason for using 10L is economy, so buying smaller cans to pour into or spending ages washing out and reusing old cans is counterproductive – could just buy smaller size cans.
I’ve simplified my lifestyle as much as possible, which includes only decorating with white paint. It suits this old house and any colour can be added by hanging pictures. It also spares the need to cut-in corners and ceilings. I wash down walls, mask everything necessary with low-tack tape and dosh out 2 coats storing rollers and trays in plastic bags for the next day saves washing them out until the current series of jobs is done.
Even better that screwfix had ‘buy a second can at half price’ on the brand I used.
(in similar vein I only own one neutral colour and style of sock…never have to pair them up and if one gets a hole then only one sock gets thrown.)
