This topic keeps cropping up and the main problem is merchants are plugging it as the KREND version or equivalent to ocr - Its NOT.
its a dubbing or scratch coat/two coats product not a One Coat Render like OCR or parmurex, it is sand and cement you may as well mix your self. there is one merchant up our way saying its the same as OCR and cheaper and he still wants £5 per bag in reality he is making a killing compared to ocr coz his buying price will be next to nothing.
if you aint sure Ring krend and ask em if they recommend spraying this at 13mm say in one coat as a finished render and see what they say
they have UF base for one coat render or even hp12,
