How does M-Seal work?

rohanprabhu

M-Seal is a sealant marketed in India. Inside the M-Seal package, there are two small plastic wrapped pockets each of which contains a play-doh [the playing clay] like material.

So.. to use M-Seal, we just have to mix those two materials and then apply to the area we want to seal quickly, because it hardens up to the hardness of concrete in that time.

So.. i just wanted to know what is the composition of the two materials and what reaction takes place that causes them to harden up like this??

thanks,
