Is this just weathered or is it chemicals?
I have been breaking down a pallet to make some bedside tables. The classification on it said it was from the USA, code 01391 and was HT. I figured it was safe to use. It was a beautiful brown and cream color but when I sanded it down the brown turned to grey and so I no longer know if I should use it. Would it have just been the weather that could have turned it that color, or has it potentially had chemicals on it?
It is such beautiful wood I really want to use it but only if it is safe. Would polyurethane seal it and make it safe?
