How to Waterproof Exterior Walls: Avoid Water Damage with Preventive Measures

The exterior walls of your home have a number of responsibilities, which includes acting as a shield to protect the interior walls and inhabitants from Mother Nature. However, without preventive waterproofing measures taken, the home’s exterior walls are inevitably bound to suffer from costly water damage.

Damage may be difficult to detect with the naked eye as the damage is likely to occur deep within the exterior walls, affecting the home’s interior walls. Living in an area like Florida, prone to rain, humidity and moisture puts a home at greater risk of suffering from this type of water damage.¬†This is why it’s vital to take preventive measures such as waterproofing your home’s exterior walls to avoid costly damages later. If you haven’t done so already, now’s the time to seriously start considering the benefits and long-term investment of waterproofing the exterior walls.

When Walls Go Unprotected

Without protection, walls that remain damp after a rain storm take some time to dry. This is particularly troublesome with continuous rain and/or additional moisture or humidity in the air. It is only a matter of time before the integrity of the interior walls begins to suffer with systematic problems such as mold and structural damage issues.

Signs of Water Damage

Visible signs of water damage include coffee colored stains on the walls, and/or wall panels that may appear as though they’re crumbling or sagging. If you notice mold seeping through the walls or detect the odor of mold in the air, you may have a costly problem on your hands. Additionally, without visible signs of mold, it is possible there may be mold inside the walls when there has been no action taken with long-term water damage issues.

Avoiding Costly Problems by Waterproofing Exterior Walls

All of this mold horror and water damage is avoidable when you hire a professional painter to waterproof your home’s exterior walls or by doing it yourself. Here’s how to waterproof exterior walls:

Find the Cause: Whether you’ve already had water issues or you’d like to prevent problems before water issues arise, you’ll want to find any and all possible water entryways. Fix any possible leaky pipes and seal any exterior wall cracks or holes. This includes brick exterior walls.

When checking for the cause or possible cause, your home’s gutters should come to mind. If you haven’t cleaned the home’s gutters in quite some time, it’s time to clean them yourself or hire a professional. With leaky or clogged gutters, your home’s exterior walls and foundation are in danger of suffering from water damage.

Prepping the Walls: To prep your home’s walls for waterproofing, you want to make sure that you’ve carefully filled in any and all holes or cracks, using a, quality filler. Once you’ve applied the filler, you’re going to sand it down and allow it to dry thoroughly prior to the application of your waterproofing agent.

Plastering: Plastering is known to offer waterproofing benefits, but if you plaster with the addition of waterproofing admixture, you’ll achieve optimum water protection results.

Applying a Water-proofer: When selecting a water-proofer, you want to select a water-proofer made of supreme quality. When shopping around for a good water-proofer, you’ll choose from a wide-variety of concrete water-proofing coating, silicate-based concrete sealer, and water-proofing paint. Before making your selection, there are a few things to take into consideration.

The concrete water-proofing coaters are permanent agents and will adhere to any type of surface. Silicate-based concrete sealers are only compatible with unpainted and unsealed walls. Water-proofing paint can be painted over previously painted walls. When you’re ready to apply your water-proofer of choice, application is easy.

Water-proofing can be applied using a simple paint roller or paint brush and as with paint, whether or not you apply a second coat depends upon results achieved with one coat. If you feel that it needs a second coat, you really can’t go wrong.

Testing Your Hard Work

You’ve gone through all of this hard work to protect your home’s exterior walls so you should give it a quick test to make sure it’ll stand up to Mother Nature when the time comes. To test your work, take a hose and spray an area of the exterior wall with water for a couple of hours. Upon completion, using a moisture meter, you’re going to check the walls to see if any moisture is detectable. No moisture equals a job well done!
