Cut 1/8-inch-wide joints into concrete floor topping when cutting action will not tear, abrade, or otherwise damage surface and before random contraction cracks develop. Saw-cut joints shall be completed within the first six (6) to eighteen (18) hours after concrete placement, and never delayed more than twenty-four (24) hours.

1. Form joints in concrete floor topping over contraction joints in base slabs unless otherwise indicated.

2. Construct contraction joints for a combined depth equal to topping thickness and not less than one-fourth of base-slab thickness.

1. Sample Sets: At point of placement, a set of three molded-cube samples shall be taken from the topping mix for the first 1000 sq. ft., plus one set of samples for each

Union Square Cafe 035300 – 6 subsequent 5000 sq. ft. of topping, or fraction thereof, but not less than six samples for each day's placement. Samples shall be tested according to ASTM C109/C109M for compliance with compressive-strength requirements.
