just to follow on from gary b's knowledgable explanation of multi vs board...
it got me wondering what exactly (chemically) is the difference and why does it matter,
gary i noticed u mentioned using lime putty to hold off finish...
bod i noticed u mentioned using lime in render sent it off quick...
thing is...put chalk in an oven for 12 hours on a high heat, you get lime...mix said lime with water and it gets hot, very hot...
so...youd expect a limey mix to go off like grease bloody lightning yes??
but it doesnt...
wtf??
got me bit of gen off some science thing btw like how do they do it or somesuch..
and the lime putty thing off some website that specialises in it..chemical company, apparently the ONLY difference between hydrated lime and lime putty is the amount of water in it...
anyone know the chemical make up of the different finishes and what reactions happen??
yeh, i know, i think to much but blame gary b...he started it..
