Do you mix it fifty fifty? Do you find it much faster than without the extra rapid ,what strength of sand to cement do you work with?I mix it and have done for years, never had any problems
I only ever used it once to go over a rendered wall where the plasterer had done all the block lines crooked. Not sure if we sbr before hand, I was in my early twenties then.not everyone likes silver sand, I think its an acquired taste
Can rapid cement be mixed with normal OPC to get a more comfortable setting time?
John what would you do if u needed to put waterproofer in to the mix as can't add any other addatives ie frostproofer ? Would be handy if u could answer this . . . Cheers
Frost proofer is the problem though CarlosI would use waterproofer and quick cem. At your chosen mix/amount.
About ten pound a bag for extra rapid upto fifteen in places, what time would a coat of render take to go off in dry conditions been put onto a scratch that has had it's drying time? That is a mix using rapid and OPc fifty fifty ?

Not sure mate I only use it when going over tanking
Say one 10mm to 15mm coat can be rubbed up after 2-3hrs.
If I don't use it you need to rub up next day.
