Sure Klean Weather Seal Siloxane PD - Great Water-Based Brick Sealer - (5-Gallon Container)

Purchase this to do my back patio. It roughly covered 1000 sq so I had to get more. After one month seems to keep brick a lot cooler in the afternoon and repels water great. Want on easily with a simple garden weed 1 gallon sprayer. Will use this product again.

Worked perfectly

This is what the pro’s use. Natural look, flat and non wet appetance. Applies easily with 1 gallon garden sprayer.

Works as advertised

Easy to apply, provides good protection to the masonry, long lasting, looks good when finished.

This product is easy to apply with a sprayer or roller and seems to provide excellent coverage. The container in which it arrives is also very sturdy and durable. However, it comes in a square plastic container with some space above the opening which means that when you turn the container upside down to get the last few ounces out of the container, it goes into those four corners of the container, making it almost impossible to pour without shaking the container and rolling it around, all the while spilling much of the remaining amount of solution. While this might not matter much with some products, wasting even a few ounces of PROSOCO Sure Klean, which costs about $250 per 5-gallon container, seems unnecessarily costly and wasteful. All that is needed here to remedy the problem is a different container design, one that provides a smooth, rounded spout for pouring that makes it easy to pour and apply the solution down to the very last drop.

A stucco contractor recommend this product specifically. We had some water coming in above a window and it was a very easy fix. Sprays on easily and is simple to work with. However, we used a lot more than anticipated, as it needs to go on heavy. I have only used this on stucco and stone walls, where it's been performing quite well for the past year. It does not completely waterproof the wall, but stops most from soaking through and beads away most passing showers. Reduces mold growth. This product is probably the best way I can try to preserve our stucco in a wet climate where stucco homes should never have been built.

Beast for sealing your fireplace chimney, highly recommended by the pros.
