Rock hard!!
I had no idea what I had ordered, not being a 'brickie', but having a need to re-point part of the front wall - having some damp on the inside on wet Winters ....
Instructions are simple, easy to follow and quite simply 'it does what it says on the ti ... box' !
Make sure you mix in the powder very well, keep mixing some more, then quite simply apply it onto the prepared wall surfaces - it's that easy.
When it sets, it really is incredibly solid. Removal of excess is possible, but it's hard work - it adheres that well!
