The color is unimportant to us because our next step will be to add heating and drywall. There are a few crucial details about Drylok that you should be aware of. 

Before you begin painting, the walls need to be thoroughly and completely dry to the touch.

Since latex and oil-based paints are porous by nature. Drylok will stick to them but lose its water resistance.

Drylok can technically be tinted, but it’s not advised. It is preferable to apply the Drylok as a white topcoat and then a complete coat of any color you like.

To be eligible for warranty coverage, Drylok must be applied twice. speaking of the warranty, it has an 18-year duration. For the record, most people do not reside in a single home for that length of time.

How to Waterproof the Walls of Your Garage Using Drylok?

You can easily waterproof your drywall with some step-by-step guidelines. As a DIY enthusiast, it should be a pretty easy job for you.

And here’s a thing you don’t need to expend the huge bill of renewing your wall. It will cut your budget. Also, you don’t need heavy equipment to do the job. 

Some brushed, And some of the cleaning solutions lying in your storehouse would do the work. Or you may have to buy one or two things from your local hardware store. 

Here are a few step-by-step guidelines we have prepared for you. 

Step 01: Prepare Your Walls

Even though it takes some time, this step is simple.

I’m going to presume that you haven’t painted your walls yet. You must first remove latex or petroleum paint that is currently on your walls. By the way, most household paints are covered by this.

Every area you’ll paint needs to be meticulously cleaned. Assuming you’re painting a raw wall. 

Your pavement may develop white streaks known as incandescence depending on how old your home is. At this point, the water’s elements and salts had coated and discolored the concrete.

Cleaning that off before applying Drylok is essential since it won’t stick to that layer. Muriatic acid is among the more potent cleansers that may be used on concrete. 

Only in extreme cases do I advise doing this.

If your walls aren’t badly soiled, a lighter cleaning solution should work. Here are some good-quality cleaning solutions you can try out.

Product 02

These cleaning solutions are lighter and it would be really helpful to clean your wall. Let’s head back to our next step. 

Step 02: Fill Any Holes Or  Cracks 

Don’t make the same mistake everyone makes because of this.  We quickly applied the first coat of Drylok to our walls. After thoroughly cleaning them and getting rid of all the dust, filth, and spiderwebs.

However, before beginning to paint, we should’ve just done a far better job of checking for any cracks and crevices that helped fill.

You may complete everything in a single day with Drylok. Because it typically takes a few days to dry completely.

Due to the fact that we were also working on some other projects. We decided to spread out the project across two weekends. To be honest, anything would be preferable to painting, so I was clearly putting it off.

We saw many cracks in my panel and a few hairline fractures after that first coat. And to be really honest, even during it. Even though Drylok is excellent, anything bigger than an Advil pill needs to be filled first.

For the avoidance of doubt, any masonry crack filler will do. Although you do not need to, I stuck with Drylok.

If it’s made for use on concrete, there are a ton of possibilities at your neighborhood Lowe’s or Home Depot, and they are all essentially the same.

Got it. Good. Let’s proceed.

Step 3: Paint The Walls With Drylok.

This section will be enjoyable if you enjoy painting. The edges and the large blank space in the center are the two pieces that make up a painted wall.

You may get a little roller for the edges, but a brush is what I prefer because I don’t really trust myself to avoid making a big mess.

You’ll need the appropriate equipment in either case:

Masonry brushes: these bristles have rougher, more durable bristles than typical paintbrushes. A regular paint brush will be torn to pieces by the cement tower’s extreme roughness in a matter of minutes.

Choose a paint roller with a nap of at least 3/4 inches. This will enable it to absorb sufficient color and evenly distribute across the uneven surface.

The kind of brush tray is not crucial. Usually, if you need to, you can get by with a replacement that you have lying around from another painting project.

Just make sure to carefully clear off any old paint first.

Similar to how you would paint any other surface, Drylok applies quite thickly. Between 75 and 100 square feet are covered by one gallon.

Although it is not inexpensive, proofing your basement walls using Drylok is much less expensive than repairing water damage caused by leaky walls.

Even if you are not planning to add a final layer of paint to alter the color, I still advise using Drylok. 

It will help your garage walls stay dry. Give it a new aesthetic, and most importantly prevent any water from coming in from the outside.

Finally, we complete the task at hand. Furthermore, your drywall is now watertight.


On drywall, can waterproof paint be applied?

The majority of paint producers provide oil- and rubber primers and paints that are impermeable and even moisture. Your basement, bathroom, and other possibly damp room drywalling jobs can be made waterproof with these products.

What is the best way to seal drywall?

Applying a coat of drywall-specific base coat is the most popular technique for priming drywall. Both water-based (latex) and petroleum (alkyd) drywall base coat types are found.

Should I leave the drywall unfinished?

Not at all. Drywall cannot be left unfinished. A poor finish that leaves exposed spaces in your apartment’s walls will come from repainting drywall before taping and mud bogging. Moisture, mould, mildew, and vermin may result from this.
