angle grinder with a dust shroud

Dont know why you would install over cement, the recommendation is using their mortar all-set. Which is modified motar, the packaging on the ditra has a list of what substitutes to use but only modified. A v-notch trowel is recommended.

Sorry just ranting this is used to prevent water from penetrating to the wood causing swelling and prevents the tile from cracking from the natural swelling and shrinking of the wood.
