1.	Do not cover Tiling with polyethylene or plywood in direct contact as it may adversely affect the curing process of grout and latex/polymer fortified Portland cement mortars.
C.	Due to the slow rate of Portland cement hydration and strength development at low temperatures, protect installations exposed to these conditions from traffic for longer than normal periods. Protect newly installed exterior adhered veneer installations from direct exposure to rain for 7 days at 70 degrees F (21 degrees C). Protection applies to the substrate, the installation of adhesives and joint grouts, post-installation rain and temperature protection until suitable cure, and the storage and handling of the cladding material. Extend period of protection of tile work at lower temperatures, below 60 degrees F (15 degrees C), and at high relative humidity greater than 70 percent relative humidity (R.H.) due to retarded set times of mortar/adhesives. For every 18 degrees F (10 degrees C) below 70 degrees F (21 degrees C) installation materials will take twice as long to cure. Large format tiles require longer curing periods in cooler temperatures. Keep traffic off the finished work until full cure. Suitable protection is to be included in the scope of the work. Each component must reach a proper cure prior to installing the subsequent installation product.
D.	Tent / shade and heat areas that will be subjected to the elements or freezing temperatures during installation and cure periods.
E.	Keep floors installed with epoxy adhesive closed to traffic for 24 hours at 70 degrees F (21 degrees C), and to heavy traffic for 48 hours at 70 degrees F (21 degrees C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors.
F.	To Replace or restore work of other trades damaged or soiled by work under this section.
