Sand color powdered particle in new furnishes shelves.
I'm building a wooden shelf for my grandfather. I gave it to him so that he can him his medicines in that along with his CPAP machine.
But a couple of days later there were wooden sand particles in the machine and it became difficult to clean it. He removed all his medicines from it. I painted it again and the same thing happened again. I thought it might be termites but how do termites feed on newly varnished wood? Every day I find dust particles in it. Can I get an answer?
