How To Seal a Brick House to Prevent Mold, Mildew, and Moisture

You have a beautiful brick house that keeps you warm and cozy but if you live in colder climate areas, the chances of getting mold, mildew and moisture into your brick home are high. The actual areas where these develop are the shaded areas that sunlight and heat can’t touch to keep them dry. Molds and mildews can cause some health problems like allergies and respiratory diseases. That’s why it’s important that you keep molds and mildews out of your house. If you are unsuccessful and they penetrate your home, you’ll find them behind picture frames or corner walls. It’s not really hard to keep them out of your home and all you need is to follow these simple tips:

  • Gather the things you need. You will need a good brick sealer. You can buy one from your local do-it-yourself store. There are some sealants that leave a glossy look on bricks. What you can do would be to test a product in a piece of brick to check what results each product can produce then pick out the sealant that best suits your preference. Remember that some brick sealants are temporary and you should re-apply them at a given time. Ask your waterproofing professional for what brand of brick sealant to purchase.
  • Clean the area thoroughly. Before applying the brick sealant, be sure that you clean the area from mold and mildew thoroughly. Look for the areas of your house where the sun doesn’t shines on especially at the corners. Use bleach and water solution to clean the molds. Be sure you scrub them all off. Let the bricks dry out before proceeding with the next step.
  • Get rid of moisture. Let the areas dry thoroughly by opening your windows and doors to exhaust damp air. You can use an exhaust fan to speed up the process and force the damp air out of the area. Use an electric light with a 60-100 watts bulb to heat small areas (this won’t work for larger perimeters). Be careful not to put the electric light too close to any flammable items like curtains or book shelves. If you are heating shelves, be sure all the items on it are removed before applying some heat.
  • Use a sprayer or any applicator for the sealant. After the bricks have dried out completely, begin applying the sealant using a garden sprayer or any applicator that you can use as long as you’re not using your bare hands. Be sure to wear rubber gloves while working with sealants. Protect your plants and flowers if you’re working on the outside of your house as well. Choose a day when the sun is out and there is less breeze in the air. This would be to prevent the sealant from drying out before you can actually apply it on the bricks.

Be sure to prevent moisture from recurring. The best thing you can do to prevent moisture from recurring is to have better circulation of the air in your home since moisture makes the environment suitable for molds and mildews to develop. Dry all your clothes before putting them into your cabinets and never keep moist clothing anywhere in your house. Use an exhaust fan in your kitchen and toilets. This will keep the air circulating and prevents dampness.
