NOTE: Do not apply sealant or coatings to a frosty, damp or wet surface or when air temperature is below 40°F. (4°C) or the
surface temperature is above 110°F (43°C). Cure times as stated below are based upon standard ambient conditions of 75°F
(25°C), 50% relative humidity. A decrease in ambient temperature will significantly lengthen the cure time. All surfaces, be
they joints or the swimming pooln proper, must be primed with Vulkem 171 Primer at a rate of 100 sq.ft. per gallon.
In joints, install a Backer Rod, 1/8 inch to 1/4 inch (3mm to 6mm) diameter larger than the joint width to all prepared expansion
joints. Set depth of Backer Rod to control the depth of the sealant. (Depth of sealant is measured from the top of the backer
rod to the top of the concrete surface.) Proper depth of sealant is as follows:
For joints 1/4 inch (6.4 mm) to 1/2 inch (12.7mm) wide, the width to depth ratio should be equal. Joints 1/2 inch (12.7mm) wide
or greater should have a sealant depth of 1/2 inch (12.7mm). Minimum joint size is 1/4 inch by 1/4 inch (6.4mm by 6.4mm).
All cracks and joints shall be sealed with Vulkem 116, and tooled flush with the surface.
Sealant can not be submerged for at least 14 days.
