Help needed waterproofing porch over basement room

10 years ago

hi and thanks in advance for your advice:

We have a 12 x 14 roofed screen porch over a basement room as part of a recent addition. Partly by plan and also because there was a parting of the ways with the contractor, we now have an OSB floor. The intention is to put tile or terazzo. How do I go on from here...

1 waterproofing I assume that I need something that will be glued on so that we don't put holes in the OSB. Recommendations?

2 once waterproofed, can we put tiles on top or will it need a layer of cement board between waterproof layer and tile?

Does anyone have experience with Ditra or Noble products in this type of work?
