I hated the walnut kitchen this house came with from day one however when we costed up the kitchen of our dreams we quickly realised that was a few years down the line. The units & doors themselves were relatively new so we decided instead of just dealing with them and hating our kitchen a lick of paint could be an amazing plan.
Using the V33 renovation paint for kitchen cupboards we took to painting all 12 doors with the paint. It did take a good 5 coats to get rid of the walnut and if I did it again I'd use a normal a primer to offset the dark tones of the wood before using this paint as the top coats. However for £36 and a days work it's been the biggest change we've done our entire kitchen is brighter and now something I can live with for many years.
