Concrete is a common material to be used in the basement, where water leakage often happened. You may perform leak repair from the outside or inside of the basement by using this item. Here are three steps you can fix leaking basement concrete with spray-on Flex Seal:
- Prepare the affected area
Ensure that the area is dry and well-ventilated, so there is no remnant of water from rain, dew, or snow. Once you have determined the area to work with, cover its surroundings with fabric cloth to prevent the Flex Seal from being sprayed on unwanted areas.
- Clean out the affected area’s surface
Remove any dust or dirt on the affected area’s surface. Use a cleaning solution and damp cloths to wipe it down if the accumulated dirt is difficult to eliminate.
After it has been cleaned, let it dry. The spray product effectively works on wet surfaces, but it works better on the dry surface. Besides, you may require painter’s tape to limit the area that’s going to be treated.
- Spray on the product
Shake the Flex Seal can properly for a minute or so. Then locate it at eight to twelve inches distance from the affected area before you spray the product in a sweeping motion.
Focus first on the holes and their surroundings before you move into the edges. Allow the first coat of spray to dry for about 24 hours before applying the second coat, then let it dry completely for 48 hours.
