Hot. Humid. Sticky.
Perfect weather for the beach, the air-conditioned mall, or peeling paint off the walls.
We've gone on at some length in the past about calcimine paint. What we've noticed is that when it is warm and humid, the latex paint on top of the calcimine becomes rubbery and releases easier from the wall. Scraping in the winter results in paint chips. Scraping paint on a hot and humid day can result in pieces of paint coming off that are a square foot in size.
We took the opportunity that the weather gave us and almost finished pulling the paint off of the wall in our guest room in just a few hours. The one wall left is the one by the chimney and it's clear that it has suffered some serious water damage followed by some very poor plaster patching. Getting it to a decent state is going to be difficult.
The room was originally pink, then blue, then the blindingly bright yellow in the pictures. Over that was two or three coats of white latex. Here you can see a patch of white latex, over the sunny, cheery yellow and the gray of a washed wall. Good Summer Fun!
