slabs, which are to receive liquid floor hardener, use curing treatment of moisture -retaining covers.
For curing by the waterproof sheet material, the concrete must be continuously moist -cured for a
minimum of 7 days. The curing process must begin immediately after final finishing.
' B. General: Carefully and thoroughly cure and protect all newly placed concrete. Provide all equipment
and materials to properly cure and protect concrete.. Keep all traffic off concrete slabs for the first 24
hours of curing. When temperature is below 55°F. curing periods shall be extended as directed by the
Architect.

Immediately after the water sheen has disappeared.
' E. Miscellaneous Curing: Thoroughly cure all work involving Portland cement Including drypack, patching,
hole filling, mortar application, and the like.
' F. Protection: Protect concrete surfaces from damage by tools, equipment, materials and workmen. No
traffic, shoring or other loading will be permitted on concrete surface until it has hardened sufficiently to
prevent injury to finish and strength.
1. Protect all flat work, and any other surfaces as required, with full board of plywood coverings as
necessary to protect from damage by Impact or from building rubbish and construction materials
and operations, including truck and other equipment travel.
t 3.08 PATCHING
A. Allow Architect to inspect concrete surfaces immediately upon removal of forms.
' B. In general, minor defective work may be repaired by use of cement mortar, but if defects are serious or
affect strength of structure, or, If patching does not satisfactorily restore quality and appearance of
surface, complete removal and replacement of concrete may be ordered.
1: Where concrete requires patching, filling or tying into, it shall be mixed, placed and finished in the
' same manner as specked for new concrete. Surface to which new concrete must bond shall be
thoroughly cleaned and coated with the specified concrete adhesive. Carefully rod or vibrate

the Architect, when color match of the adjacent concrete is not required.
3. All structural repairs shall be made with prior approval of the architect, as to method and
' procedure, using the specified epoxy adhesive and/or epoxy mortar. Where epoxy Injection
procedures must be used, an approved low viscosity epoxy made by the manufacturers previously
