How to Waterproof Concrete Steps
If you're looking for a great way to protect your outdoor concrete steps from water, moisture and rain damage, you may be curious about how to waterproof concrete. If so, you'll be pleased to learn that your concrete steps can be waterproofed in just a few easy steps.
Step 1 - Prep Your Concrete Steps
Before proceeding to waterproof your concrete steps, you will need to give your steps a thorough cleaning. Use a mini vac, broom and dustpan, feather duster or some combination thereof to remove all traces of dust from your concrete steps. Once the steps have been successfully dusted, produce a homemade cleaning solution of warm water and mild liquid soap, then give the steps a vigorous scrubbing with the aid of a hard-bristled scrub brush. If you encounter any particularly stubborn stains, try using a wire brush. After the steps have been sufficiently cleaned, use a garden hose to rinse off your cleaning solution. If you don't feel like waiting for the freshly cleaned steps to air dry, you can use a wet/dry vac to suck up any remaining moisture.
Step 2 - Apply Your Initial Coat of Waterproofing Sealer
Having administered a thorough cleaning, you are ready to waterproof your concrete steps. Begin the waterproofing process by pouring your concrete waterproofing sealer into a paint tray. Use a paint brush to carefully apply a coat of concrete sealer to the edge of each step using smooth, even strokes. Once the sealer has been applied, allow it to fully dry before moving on to the next step. Although drying time varies from brand to brand, you can generally expect to wait between 6 and 8 hours.
When working with concrete waterproofing sealer, it is recommended that you wear a paper breathing mask in order to protect yourself from fumes. If, at any point, you feel yourself becoming overcome by fumes, take a break far away from the area in which you're working. It's also a good idea to don a pair of protective goggles to shield your eyes from any unexpected paint drips. If you are attempting to waterproof concrete steps that are located indoors, make sure to carry out the job in a well-ventilated area and to wear a heavy-duty breathing mask.
Step 3 - Apply Your Second Coat of Waterproofing Sealer
Now that your initial coat of sealer has had ample time to dry, it's time to finish waterproofing your concrete steps. Using a paint roller or a large paintbrush, apply your waterproofing sealer to the unsealed portions of the concrete steps. Again, make a point of using smooth, even strokes and take care to avoid applying too much sealer at once. Once you've finished applying your second coat of waterproofing sealer, allow it to fully dry before applying any additional coats.
