You’ve just finished building your dream home, and it’s looking beautiful. The only thing is the exterior walls still need some attention. Waterproofing these walls can ensure that your home stays in pristine condition for years, but it can be challenging. This article will show you how to waterproof exterior walls by providing tips on cleaning and sealing the surface so that moisture doesn’t get inside your house!
Clean The Surface
The first step in waterproofing an exterior wall is to clean the surface. You’ll need to remove any dirt and grime from the wall, so start washing it with a pressure washer.
If you don’t have access to a pressure washer, you can use a scrub brush instead. It will be slower going than using a power tool, but it will still get the job done effectively.
Before you start cleaning your exterior walls with either method, make sure that there are no plants or shrubs growing close enough to be harmed by overspray or runoff from your water source (either the hose or pressure washer). If there are any plants near where you’re working, move them out of harm’s way while keeping them watered until they’ve been replanted safely elsewhere.
When scrubbing away dirt and grime with either method (power tools vs manual labor), make sure to press only a little hard on your walls; this could cause damage over time if repeated regularly enough! Instead of pressing down with all of your strength each time, let gravity do most of the work for you by leaning into each stroke as needed—just keep in mind that this method may require more elbow grease than usual when compared to other cleaning methods used throughout history due to its reliance on human energy rather than mechanical assistance (such as running water through pipes!).
Patch Holes And Cracks
You can use a patching compound to repair holes and cracks in your exterior wall. To apply the patching compound, you’ll want to cover the entire area with plastic sheeting. Then take some of the patching compounds and apply them over the hole or crack. Let dry for a couple of hours, then sand down any rough spots and apply another layer of patching compound.
When applying the waterproofing sealant, use an electric sander (or sandpaper) to smooth out any rough edges from your previous work. Remove excess sealant from the surface by gently scraping away with a putty knife until all visible areas have been covered with a nice, even layer of waterproofing sealant. For best results when applying your sealant, roll it on using an extension pole and let dry for at least 48 hours before painting with exterior paint or stain.
If you don’t wait long enough for the sealer to adhere properly to your walls, the paint will not stick well and may flake off in large chunks. The longer you wait, the better the sealer will adhere to your walls because it gives extra time for air bubbles and moisture-related issues like mildew or mold growth to dissipate.
In conclusion, there are many different ways to waterproof exterior walls. The key is finding the right combination of the best products and techniques for your home. Remember that these methods should be used in addition to other preventative measures such as sealing windows and doors, keeping gutters clear of debris, etc.
