When set sufficiently, the brown coat shall be uniformly floated with a dry float to promote densification of the coat and to provide a surface receptive to bonding of the finish coat. Brown coat shall be fog cured for a minimum of 72 hours.

Section 09 24 23 Page 5

3.7.4 Finish Coat

Dampen surfaces of the brown coat not more than 1 hour before the finish coat is to be applied to a uniform wetness with no free-standing water on the surface. The finish coat shall have a smooth float finish and shall conform to the approved sample. Fog cure the finish coat for a minimum of 48 hours. Take care to prevent staining.

3.7.5 Surface Tolerance

When a 10 foot straightedge is placed at any location on the finished surface of the stucco, excluding rough-textured finish, the surface shall not vary more than 1/8 inch from the straightedge.

3.8 CURING AND PROTECTION

Perform fog curing by applying a fine mist of water to the stucco.

Exercise care during fog curing to avoid erosion damage of the stucco surfaces. Do not use a solid stream of water. Fognot less than three times daily. Protect the stucco from the direct rays of the sun during severe drying conditions using canvas, cloth or other approved sheet material.

3.9 PATCHING AND POINTING
