Baz la, nan kou, se yon siman-sab mòtye. Pou jwenn-wo bon jan kalite nwa solisyon, sou yon creole par (1 bokit siman 3 bokit nan sab) ki te ajoute yo apeprè 500 gram nan kabòn nwa (swi). An egzak wo nan kabòn nwa a nan la solisyon yo detèmine pwouve li. Li ta dwe vin chonje ki yon kantite lajan twòp nan carbon nwa pouvwa mennen nan yon diminisyon nan fòs pwopriyete yo nan mòtye jwenti.

The basis, of course, is a cement-sand mortar. To obtain high-quality black solution, on a standard batch (1 bucket of cement to 3 buckets of sand) is added to approximately 500 grams of carbon black (soot). The exact proportion of carbon black in the solution is determined empirically. It should be remembered that an excessive amount of carbon black may lead to a decrease in the strength properties of mortar joint.
