smallest Enrich N Seal is 473mls but why mess around with a client like that??? Buy a gallon and tell him you are gouing to do a large test area for his assessment that he needs to pay for!
With regards the other product it was used to seal some of the Pyramids and Sphinx in Egypt to stop them crumbling. It is a two part system where you apply an impregnatiing pre sealer and allow it to cure then you add a further sealer that is both topical and impregnating which bonds in three ways, it bonds subsurface, it attachs to any molecules sticking up from the pre sealer and it bonds to the surface. Now whilst it worked very well in both those situations what was not checked was Traffic wear because at the end of the day the most it is going to have is the odd idiot scrambling on it but it certainly isn't going to have cars driving on it. I must also re-iterate I am not using the word EXPENSIVE lightly!
