Question:How many square feet does one bag cover

Answer: Thank-you for asking this question: I have added a coverage chart to the pictures for Schluter; Set, All-Set, and Fast Set.

Question:Can I use All Set to install ditra over 10 day old concrete?

Answer: Yes, The opened ribbed structure on the underside of the ditra mat allows the vapor released from the concrete to neutralize and in a lot of cases makes the concrete stronger because the moisture evaporation is slowed down in the concrete slab.

Question:How many sq feet does a 50 lb bag cover? Previous answer refers to a picture... where is that picture?

Answer: The second image in the product image gallery shows the coverage specifications for this product.

Question:I was always under impression that only unmodified should be used over ditra , is this modified shluter thinset ok to use over ditra ?

Answer: This is the answer from Schluter regarding the use of other manufacturers’ modified thin-set mortars to install tile over Schluter boards and membranes. .inNo .in Schluter's position on the use of other manufacturers’ thin-set mortars within their systems in general has not changed. .inWe have no control over the formulation of other manufacturers’ products and therefore cannot guarantee consistent, positive results with their modified thin-set mortars when installing tile to Schluter® boards and membranes. We continue to warranty other manufacturers’ modified thin-set mortars to bond DITRA to approved substrates.
