PREPARATION:
When laying glass block, brick or concrete block, be sure that the footing is
sound and adequate to support the load. When repairing mortar joints remove
all loose and foreign material. Dampen areas to be repaired just prior to
application.
MIXING:
Empty the contents into a mortar box, wheelbarrow or mechanical mixer.
When mixing by hand, form a crater for adding water.
Add approximately 3.5 quarts (3.3 L) of water per 50 lb. (22.6 kg) bag or
enough to achieve a workable mix. If too stiff, add more water
a little at a time. Avoid a soupy mix. Excess water reduces strength and
durability and can cause cracking. In cold weather use warm
water to accelerate the set. Use cold water to slow the set in hot weather.
Retempering impairs performance.
