Product Overview

I recently had the opportunity to try out KILZ Basement and Masonry Waterproofing Paint, and I am so glad that I did. This is a great product for anyone looking to waterproof their basement or masonry walls. The paint is easy to apply and provides a durable finish with excellent adhesion. It s also a great way to update the look of your home s exterior.

This paint is formulated with nanotechnology, which forms a barrier to help stop water infiltration while an alkali resistant coating provides a long lasting, durable finish. In addition, it is designed to be used on both interior and exterior surfaces. It is also suitable for use on properly prepped and cured above and below grade basement walls, masonry walls, retaining walls, cinder blocks and concrete blocks, stucco and brick.

Applying this paint is easy and straightforward. It can be applied with either a high quality 1/2 3/4 nap roller, 4 nylon/polyester brush or an airless sprayer capable of delivering 2200 3200 PSI or greater using a .023 .025 spray tip. Additionally, prime all uncoated, patched, chalky and adjacent wood or metal surfaces with KILZ Premium Primer before applying this paint. For below grade application, it s also important to fill all holes/cracks with hydraulic cement prior to painting.

A minimum of two coats of this product are required for optimal results and it dries to touch in only one hour so you can quickly get back to enjoying your newly painted space. However, depending on the humidity level, it may take up to four hours before you can recoat the area again.

Overall, I found KILZ Basement and Masonry Waterproofing Paint to be an excellent option for anyone looking for an easy way to waterproof their basement or masonry walls without sacrificing style or durability. It provides excellent adhesion and long lasting protection against water infiltration while creating a beautiful finish that will last for years.
