We’re often asked what redgard is as a company specialising in waterproofing. Is it a coating? A paint? A sealant? Well, all of these things can be answered with yes: redgard can act as all three. But that doesn’t fully answer our question. So what exactly is redgard? What does it do? And how can you use it effectively on your waterproofing project? Let’s find out!

Necessary Tools for Applying Redgard

The best way to apply redgard into concrete, stucco, or any other impervious surface is by using a Sprayer, Roller, and Trowel. Please don’t use anything smaller than a standard trowel because it will make it more difficult for you to spread it over your surface. You also want to avoid applying it with paint rollers; they won’t provide consistent coverage over your application area.

How to Apply Redgard?

If you want to apply redgard efficiently, take a roller or and cover each area in long, even strokes, before using redgard. At first cover those cracks with suitable tape. This will ensure the waterproofing on those crack areas. Make sure that you cover all visible damage with redgard before moving on to another spot. Be careful not to put too much waterproof on your surface because it can be difficult and expensive to remove after it dries.

After covering your first area, continue working until your entire floor is completely covered. If any areas have missed damage spots after applying redgard, repeat until they are fully coated in waterproof. Once your whole surface has been covered, let it dry for about at least 60 to 90 minutes. You should notice a huge difference after drying. During use, the color of redgard is usually pink, but it becomes red after drying. Most people see an immediate difference in their cracked walls when they’ve applied Redgard successfully.

After drying the first layer of redgard:

  • Use the second layer of redgard.
  • Again paint over every crack or damage area with long stripes of redgard.
  • Again allow sufficient time to dry. Usually, 1 hours should do it.
  • Recoat again if necessary.
  • As mentioned above, allow 15-20 mils (3-4 mm) coating per coat depending upon climate conditions.

So if you need three coats, just make sure that you have 30 mils (6 mm) coverage per application; although if you need more protection, simply apply more than three coats till the total protection desired is achieved. But give enough time interval between applying each layer of redgard to become dry.

Common Uses for Redgard

Besides waterproofing, Redgard has found many uses in residential and commercial properties besides waterproofing. For example, it can be used as a dehumidifier for items that you want dryer, reducing unwanted moisture in your closet or other areas of your home. This chemical can also be used as an anti-rust agent on steel surfaces such as grills or tools that you want to be protected from rusting.

In more industrial settings, though, Redgard will most often find use during waterproofing operations. A good, high-quality water sealant is one of several key steps when performing repairs on roofs and basement floors. This type of sealant helps protect against leaks over time while keeping materials dry below even under great pressure. Many people install Redgard to prevent flooding disasters in their homes or businesses, but several instances have proven invaluable using these products even after disaster strikes.

Tips on Using Redgard

1. Make sure you have covered all the cracks with good quality waterproof tape.

2. Make sure you have applied primer before applying Redgard. Otherwise, it will not stick on the walls properly.

3. Make sure the wall is dry, clean, and free from dust or loose paint when applying Redgard. If the paint is flaking, use a scraper or similar tool to remove loose flakes before priming/applying Redgard. DO NOT APPLY REDGARD ON FLAKING SURFACES!

4. When priming walls with plaster-based paint, primer should be applied directly onto the wall using a paintbrush or roller and then left for at least an hour before applying Redgard.

5. Apply a generous amount of primer to the entire wall area you want to cover by applying it onto the ceiling first and then working down towards the floor. A thick coat of primer will provide adequate surface area for maximum adhesion between wall and adhesive during the application process.

6. Apply an even coat with overlapping strokes, brushing from top to bottom in a consistent stroke pattern at a minimum of 1 sq ft/min.

7. Allow the wall area to dry for before applying the first Redgard layer.
