Wood subfloors
I have an older home built in 1900. When refinishing the second floor floors, I have noticed wide gaps in the wood plank subfloors. I want to use the floor as my top floor.However, after staining, I find small, rock like substances coming out from in between the planks. What is Iran’s how do I fill in the gaps?
