Why do we have to use 100% acrylic latex paint on your products?

The reason we have to limit certain type of coatings is that some coatings can actually attack the board - in various ways. That is, some oil or alkyd based paints and stains, acid and vinyl copolymer based stains/paints can cause failure of the bond of our primer to the board face. Further, some coatings can actually effect the board itself and (long term) lead to ILB (inter-laminate bond) failure and performance issues with the board itself.
