That said, there are many different types of commercial waterproofing products you can use to protect your exterior walls from such damage. But if you've already narrowed your options down to waterproofing paint, you might want to learn how to paint your walls just like a pro would.
Continue reading on below to find out how to achieve decent results when applying waterproofing paint on your external walls.
Prepping your walls for the paint job
Before you can start painting, you should inspect your walls to check for signs of damage in the masonry. Look for faults like cracks and holes and patch them up with a good-quality filler. If these surface blemishes are left unattended, then the waterproofing paint won't be effective at its job.
Once the filler in the patched up areas of your walls has dried properly, sand down the rough, uneven areas until you achieve a smooth, even surface. Make sure you remove dust from the surface of your walls by hosing it down with a regular hose. If there is stubborn dirt and grime you need to get rid of, a pressure washer can come in handy.
Once your walls are clean and dry, apply waterproofing primer to ensure good adhesion between the substrate and the waterproofing paint.
Mix your paint and start painting
When the primer is dry, your walls will be ready for paint application. You'll need to mix your paint according to the manufacturer's instructions, take a paint brush or roller designed for masonry, and start painting.
Often, you'll need to apply more than one coat of paint. If multiple coats of paint are required, allow each coat of paint enough time to dry properly before applying the next coat. Make sure you use a sufficient amount of the product so you can create a waterproofing barrier that will be effective at protecting your walls from moisture and water seepage.
Paint from the top to bottom. This way, you'll be able to catch any paint drips as you go down the wall.
When you waterproof your exterior walls, you'll be protecting your commercial premises from serious moisture and water damage, but also preserving the value of the property. If you need help with applying waterproofing paint on your external walls, don't hesitate to seek out a professional commercial painter.
