Hello, we have a fiberglass pool (salt) with travertine coping and paver decking. Do we need to seal them? Our pool builder thinks it is not necessary to seal the pavers. Also, they put polymeric sand between the pavers and when it rains, the sand softens up and some of it ends up on the paver surface. According to the pool builder, it is normal. Do you think it is normal to have some loose sand on pavers?
Thanks in advance for your input.
