INSTRUCTIONS FOR MIXING AND CURING
"DES-CRETE" INSULATING FLOOR MATERIAL
MIXING
1. For Hard Floors - Heavy Traffic
- Three (3) 50 pound bags "DES-CRETE" to one (1) 98 pound bag Portland cement,
and approximately twenty-one (21) gallons water.
2. For Medium Floors - Light Traffic
- Four (4) 50 pound bags "DES-CRETE" to one (1) 98 pound bag Portland cement,
and approximately twenty-six (26) gallons of water.
Place the "DES-CRETE" in a mortar mixer first and add the Portland gradually. When these
ingredients are well mixed, slowly add water.
DO NOT ADD TOO MUCH WATER.
Test mixture as follows:
- Form a ball out of the mixture.
- Toss it about 12" into the air and catch it in your hand.
- If it breaks apart or crumbles, it is too dry.
- If it flattens out or deforms considerably, it is too wet.
- The ball should remain reasonably intact if the mixture is correct.
CURING
1. Air dry for twenty-four (24) hours at room temperature.
2. Heat oven to 200°F and hold at this temperature for 1-1/2 hours for every inch of floor
thickness (3" thick floor = 4-1/2 hours).
3. Increase temperature 50°F per hour until maximum temperature is reached.
SURFACE CONDITIONING
After curing, the surface of the floor may be sprayed or painted with a solution of Silicate of
Soda—diluted one-to-one with water.
This will further seal the surface and prevent dusting.
