Apr 24, 2017· The same sodium silicate can be used to repair engines, as well. Head gasket leaks can be repaired by putting some sodium metasilicate in the coolant water. The water circulates, and some passes through the hole in the gasket. The gasket's elevated temperature changes the sodium metasilicate at the metal's surface, producing a film that seals ...
Aug 13, 2014· Sodium silicate solutions perform very poorly and ineffective as waterproofing sealers since they have a limited depth of penetration and they are unable to stop or reduce hydrostatic pressure. If you want to densify your concrete a sodium silicate hardener is an excellent option; however, leave the waterproofing to one of the other methods below.
