We had a problem in the past where one of our plasterers “keyed” the tanking slurry before rendering which stopped from working. Schoolboy error! Using sand and cement to form a splatter coat before rendering is time consuming and means that you cant apply the render until the next day (at the earliest!)
This stuff saves loads of time as you can do the splatter coat and then render the same day. Great stuff. Bit pricey though….
