Chimneys are more exposed to bad weather because they project above the roofline. Therefore, it is important to set aside enough time for maintaining the chimney. Throughout the year, the chimney takes quite a beating from different weather conditions. In a stormy weather, water penetration causes deterioration and costly damage in the chimney.
Waterproofing is an effective solution for extending the life of your chimney and protecting it from costly damages. The most essential parts to focus on when waterproofing include brick and mortar joints. Here are steps that will help you waterproof the chimney and keep it from getting damages.
Getting chimney measurements and cleaning it
When you measure the entire chimney, you will be in a position to know how much material you require for waterproofing. Therefore, measure all the sides of the chimney to figure out the total area. Find the area of one side of the chimney and multiply it by four to get the total area of the chimney. In case your chimney has substances such as rust, dirt, mold, efflorescence and creosote among others, you will have to remove them first. You can scrub the tough areas with a stiff bristle brush if necessary before rinsing thoroughly with hose water. Leave the chimney to dry for 24 hours after cleaning.
Watch out for non-target sections
It is important to look out for non-target sections to avoid over-spraying on the shingles. Over-spraying on the shingles may cause discoloration. When working on the base of the chimney, always use an absorbent material. Plastic drop cloths are not ideal for use because the material can easily become slippery causing the overspray to run off into the roof. There may also be windows and sidings within close range of the overspray. In case the overspray ends up on these surfaces, it can be easily wiped off while it is still wet. Leaving it to dry makes it hard to remove.
Minor chimney areas
When you notice minor cracks in your chimney, you should repair them before you start waterproofing. There are repair products that you can use to fix all minor cracks at the chimney. In some cases, the damages may be severe. Therefore, you will have to consider services for waterproofing in Toronto offered by experts who have vast knowledge in rebuilding and tuck-pointing. If your chimney has been recently tuck-pointed, you should give it several days for the mortar to cure before applying water repellent.
Applying an ideal water repellent
First, you need to know the difference between a sealer and water repellent. Water repellent allows the chimney surface to breathe while keeping water out. Sealers keep both air and water from permeating through the chimney surface. It is recommendable to use water repellent instead of the sealer. Water repellent allows moisture that may be trapped inside the chimney- to escape.
When applying the repellent, start from the bottom as you work your way to the top. Apply a flood coating as well to saturate the chimney surface to make it easy for the repellent to soak in effectively. A soft bristle brush will come in handy when you need to spread the repellent evenly across the surface. After applying the repellent, you can clean up the chimney now, resting assured that chimney leakages are a thing of the past!
