Step 1.5. Slurry
A skim coat of slurry
Slurry is a paste-like mixture of A powdery type substance made from a mixture of earths materials such as limestone and shale, which is sintered (cause to become solid mass by heating without melting), ground, and mixed with small amounts of calcium sulphate and calcium carbonate. Cement is activated by water and when mixed with gravel and sand, forms concrete. and water with maybe a little bit of fine sand if you want to add a bit of substance.
As mentioned on the previous page, I kept the hypertufa moist and covered with polythene for ten days (the The hardening of concrete. The process of becoming hard or solid by cooling or drying or crystallization. In concrete application, the process in which mortar and concrete harden. The length of time is dependent upon the type of cement, mix proportion, required strength, size and shape of the concrete section, weather and future exposure conditions. The period may be 3 weeks or longer for lean concrete mixtures used in structures such as dams or it may be only a few days for richer mixes. Favorable curing temperatures range from 50 to 70 degrees F. Design strength is achieved in 28 days. period).
On day 4 of the curing period we added a skim coat of slurry.
Because the hypertufa was going through the curing period, it would adhere well to the slurry.
First Angela gave the hypertufa a bit of a brush to get rid if any loose stuff.
Then she mixed 3/4 bucket of cement, 1/4 bucket of fine sand, and added water as needed to a paste-like consistency.
And then she poured it onto the hypertufa.
She then spread the slurry about with a gloved hand and smoothed it off with a trowel.
The hypertufa had a roughish type texture and the slurry was like the icing on the cake.
The slurry was just thick enough to cover the rough texture of the hypertufa.
Once the slurry had been smoothed, we ensured that it stayed moist while we waited about three hours for it to firm enough to allow the Any broad, thin surface. of polythene (plastic) to go back on.
Of course, firming times could vary greatly depending on climatic conditions.
