The Basics of Masonry Waterproofing The Basics of Masonry Waterproofing
Masonry waterproofing is an excellent way to preserve the life of your masonry projects. Rain, sleet, and snow can do significant damage to your brick and cement stairs, brick walls, or brick fence columns if they are not properly waterproofed. Over time, the water can seep through seams and grout of your fixtures and cause them to crack and become unsafe and structurally unsound.
Once you have completely built or renovated your masonry product, it is a great idea to waterproof it with a masonry waterproofing product soon after so that it is immediately protected from uncertain physical damage. Masonry waterproofing comes in a variety of colors and is more cost effective than plasters and paints. Do not apply waterproofing products to your brick or cement fixtures in rain or freezing temperatures.
Remove any dirt or dust from the surface of your fixture by using a stiff bristled scrubbing brush. Ensure the area is cleaned thoroughly. Any foreign debris that is on the fixture will cause you to not get the maximum performance from your masonry waterproofing product.
Mix the masonry waterproofing product you choose per the instructions on the container. Stir the mixture constantly with a wooden paddle until it is smooth and no lumps in the mixture are visible. Allow the mixture to sit for 10 to 15 minutes. Use the mixture within one hour of mixing.
If you plan on using your masonry waterproofing to decorate your structure, you should know that the entire wall should be completed without any interruption. If you should stop in the middle of the application for even half an hour, you will have very noticeable overlaps and patch marks because of how the waterproofing solution dries. If there are any light fittings or cornices in your masonry structure, you will have to cut around them when you get to them during the application process. In conventional painting, you are able to cut around the fittings and cornices first and come to them again during your painting process without being concerned if there will be a noticeable overlap.
Wet a section of the surface thoroughly with clean water from a hose. Stir the waterproofing solution again and apply it to the wet section of surface of the fixture using fiber or whitewash brush. You should stir the solution frequently during application process to prevent it from settling. As soon as you can see the waterproofing solution starting to dry, cure it by wetting it with a mist of water evenly. You should do this at least two to three times.
Before applying the second coat of waterproofing to your masonry fixture, allow 6 to 8 hours for curing. You will follow the same procedures as you did when applying the first coat. Your masonry structure will absorb as much of the waterproofing solution as necessary to render it waterproof. You will recognize this by the powdering of the area. At this time, all that is needed is a dusting or washing off of the excess powder.
