I done exactly the same thing mate! Was pissing down outside so couldnt spray in the garage because of the moisture. So brought the wing inside the kitchen, masked up all the surfaces and put blankets everywhere. So thought no one would know...
I thought all the paint particles would just fall to the floor... but they didnt they were over every single brick on the walls in the kitchen, over the aga and everywhere. I had to t cut off the fridge freezer, the aga had to stripped and repainted, and my dads favorite brick walls were rendered over! He got the brick arch over the aga sand blasted but made so much mess decided not to with the walls.
One of the many times i was in shit as a kid!
