We put up beaded board & chair rail in hubby's bathroom to protect the walls from his wheelchair. Now have called a painter to prime and paint. She claims latex primer & paint won't adhere to bare wood and wants me to go out and buy oil-based products, ignoring the substantial investment I've already made in top-grade latex ones. Given my research, I think she's an idiot and I should find another painter. Opinions, please?

Thanks for the reply
