How to Seal The Foundation of Your Home To Prevent Flooding: D.I.Y. Tips For Beginners
A flooded basement is more than just a messy inconvenience; it can also cause significant damage to your home and its foundation, especially if your basement is subject to frequent leaks or you live in an area with lots of precipitation. Sealing the foundation of the basement is critical to prevent flooding, but not all sealing foundation methods are created equal. To truly treat your basement effectively, there are a few critical steps to take, including selecting the right materials for the job.
Whether you're a DIY home improvement specialist or you're looking for ways to keep the costs of sealing your foundation down, the team at Liquid Rubber has got you covered. We feature the best and most reliable methods for waterproofing the basement and have a guide of DIY tips for beginners and weekend warriors.
Why Should I Waterproof My Basement?
Basements are built below grade, meaning that they're flush with the ground, not built above it. This means that they naturally will take on water, which you may note by seeing or feeling damp basement walls or seeing puddles on the floor.
Damp basements can lead to a host of problems for your home, including peeling paint, rotting wood, damage to stored items in the basement, and growth of mold and mildew. Mold and mildew can lead to health problems for everyone in the home if left unchecked. Plus, a basement that's damp may also start to affect the foundation of your house, too, causing it to shift and become unstable.
Although builders will take steps to waterproof your basement, over time, the house can settle and cracks may occur in the basement walls. Plus, when the soil around your house is saturated with water or from snow melt, then moisture will seep through the cracks and further damage your home. While a dehumidifier can mitigate some of the damage, waterproofing your basement will give you the best results long-term.
DIY Tips For Sealing Your Foundation
Liquid Rubber Foundation Sealant is an excellent product for waterproofing your basement and much, much more. It's easy for even a novice DIY-er to apply, and it can last for quite a while, as long as you've properly applied it.
Here is the right way to apply Liquid Rubber to your home's foundation.
First, Liquid Rubber can be applied over "green" concrete, but it's usually better if the concrete has been cured for at least 28 days. It can also be applied over existing solvent-based existing coatings; although, if you notice substantial cracks in your foundation, then you'll want to consult with a professional before proceeding. Look over the surface before starting your project.
General Preparation & Cleaning
Liquid Rubber works best on a smooth, clean surface, and you'll have a better result if you prepare the surface first. First, make sure that you grind down sharp edges and repair voids, honeycombing, cracks, and flaking concrete. Make sure that the surface is free from curing compounds, laitance, spalling, oil, grease, dirt, mud, or other debris. Pressure wash the entire area and allow it to dry, using a pressure washer with a minimum 1400-psi. Allow the surface to dry for 24 to 48 hours before applying your Liquid Rubber Foundation Sealant.
How To Apply
Apply the product with smooth, even strokes, just as if you were painting your nails. Include the inside and outside corners, wall—to—wall, and don't forget your slab. Be sure to get the footing junctures and the cold joints and cracks, too. Brush a heavy coat with smooth, even strokes, and you can even coat around the brackets, joists, and clip to ensure that the entire area is protected from water.
Tape or otherwise section off any area that you don't wish to have foundation sealant applied to before you start. Then, remove the paint while the sealant is still wet. You can use a brush, roller, or even a heavy-duty hydraulic piston spray rig.
Allow 24 to 48 hours to dry before backfilling (if you're applying to the exterior) or before painting over an interior wall.
