My daughter has drawn all over my living room walls with crayons that were supposed to be washable. I decided to prime and paint my living room, since the crayons were not coming off the walls. The staff at the Germantown Ave Benjamin Moore are wonderful! The store is located in the most adorable part of Philly called Chestnut Hill, and despite having more customers than staff, I was greeted right away. I bought the most beautiful shade of light sunny yellow, and so far, this paint is covering thick and nice in just one coat, as promised!
