Almost didnt buy it because delivery estimate was 2 weeks, but couldn't buy it locally. Item was delivered in just 3 days. So, five stars for delivery! Hubby and I are waterproofing the basement with quickwall cement (excellent product by the way). The walls are stone and sand with a thin coating of plaster where there is still plaster. Started project by hand...took 3 hours to cover a 5 ft x 8 ft. area. Attached the Mophorn sprayer to an air compressor and were able to do the same area in about 20 minutes. Clean up takes a little longer with the extra tools, but overall a big big big time saver...and looks professionally done. (Laying tin foil along the edge to collect cement that drops will also help cut the clean up time.)
