Full "detailed" instructions come on each bag:
Mix 51⁄2 quarts of water per 50 lb. bag of SL-150. Always measure
the water added. Do not mix by feel. Always add powder
to the liquid. Mix with a high-powered drill at 500-1000 rpms
using a "Wagman WMP-30" or other appropriate mixing paddle.
Mix to a liquid, creamy, lump free consistency. Spread as quickly
as possible. For deep pours that require an increase in elevation
from 1" to 5", SL-150 should be reinforced with clean dry pea
gravel having an average diameter of 1/8" -3/8". Pea gravel
should be mixed at 15 lbs. per 50 lb. bag of SL-150. Additional
patching or smoothing may be required if pea
gravel is added to the mix.
