The term lawn, referring to a managed grass space, dates to no earlier than the 16th century. Tied to suburban expansion and the creation of the household aesthetic, the lawn is an important aspect of the interaction between the natural environment and the constructed urban and suburban space.
Allow thinset to dry for 24 to 48 hours. Thinset mortar adheres tiles to floors, countertops, backspashes and walls. It shouldn't be walked on or disturbed during the drying process, as doing so could cause a serious misalignment of the tiles you just laid, a problem that would be difficult to fix.
