Adhesive query for large format tiles

[Spud]

I was told on my course at PTS any powder adhesive made abroad didn't have an inhibitor in for chronium 6. where as any powder made in the uk does have an inhibitor in to get to British standards and that if you did use an adhesive imported from italy that there is a chance of cement burns. Could you find out if this is true?

thats not true , any adhesive manufactured in the european union must have inhibitors to limit the chromium vi its a european law

chromium vi is a by product of many industrial processes ,the inhibitors referred to are binders that bind to the chromium vi to stop its harmful effects these binders loose their effectiveness over time hence dates on adhesive bags never use out of date adhesives.so eu directives were passed to enforce adhesive manufactures to limit the amounts of chromium vi in their products so they are at a safe level

Where do the burns come into effect?

i didnt mention any burns but while we are on the subject skin contact with high levels of chromium vi results in dermatitis ,burns ,i can only guess could be high levels of alkali this would burn your skin
