"Great filler. Very easy to work with and very easy to sand once dry. this item drys really fast and is great on shallow and deep filling. however because it drys fast make sure the lid is quickly replaced as it also quickly drys in the tub once exposed to fresh air. i have used tis product for internal and external work and it works fine. i wouldn't say itys the cheapest of fillers although the time you save using it pays for itself. i would recommend this product to others. overall 9.5/10 due to cost would be 10/10 if cheaper."
"Sets like concrete and a swine to sand down if you apply too much. Best to keep a eye on it and do a preliminary sanding before it cures completely. Masonry paint appears to take longer to dry over it, compared with adjoining areas, even on a warm day in June."
"Used this for all sorts of jobs. Only problem is it takes a while to set if you fill a deep hole. It's also tough to sand - wouldn't recommend it for filling holes in plaster for example unless you can get it dead level and avoid sanding. (it's so tough, it's hard to sand it flat without sanding the surrounding plaster away even faster)"
"Looking at the other reviews, maybe I had a duff tub, but I found it had settled a lot in transit and needed a good 15 mins mixing, then hen using it, it dried out to be pretty weak and a bit crumbly. I'll avoid in the future or at least try the mix yourself stuff."
