Things You Must Know Before Buying Concrete Adhesive

Undoubtedly our list contains the strongest glue in the world. But you may not need it. Probably you've got a specific need that can be better suited by some other adhesive. To pinpoint the exact one from the above twelve, use these criteria:

Location

Depending on the construction work location, you may look for site-specific features of the adhesive. For example, unlike the interior, the impact of sun, rain, mud, snow, or extremely low or high temperature should be considered for the exterior.

Macro aspects of the site, such as its altitude, flat-field or slope, etc., are also issues to be considered. The climate is another crucial factor you mustn't forget.

Specialization

You'll often find phrases like "recommended for" or "specifically designed for'' in the instruction manual or the glue's packaging. If you get an adhesive that suits your specific use, you should choose it.

Holding Power

High holding power is one of the key aspects you should look for in a concrete-adhesive. Not only will it add longevity to your structure, but you will also save some nails, screws, and, more importantly, time and effort in the process.

Durability

In construction work, nothing is as critical as durability. You want your house, pavement, road, or whatever else you're building to last through the ages. And you definitely want to avoid the annoying repair work time and time again.

To avoid the pilling back or chipping off of concrete, you should go for polyurethane adhesives. They have a drawback, though; they're not waterproof. So for outdoor jobs, you must use either thin-set mortar or epoxy. The latter is better.

Versatility

Versatility is important for comparatively bigger projects involving different jobs, such as indoor and outdoor works, bathroom and bedroom, etc.

Among three primary types of concrete adhesives: polyurethane, thin-set, and epoxy. Thin-set adhesives are the least versatile but they're cheap, waterproof, and easier to use. Despite having a short shelf-life and long drying period, polyurethane is the most versatile.

Epoxy adhesives come at a higher cost, but they are heavy-duty adhesives. Thus, they're the most durable and versatile among all three categories.

Consistency

The ideal concrete glue should be easily picked up and carried by the construction tools/appliances, and it can be spread easily onto the substrate. The adhesive washes out easily if the formula is thin, whereas thick ones are difficult to disperse.

Substrate

The material immediately below the finishing is called a substrate. In our particular case, concrete. Depending on whether the concrete is dry or damp or the grading of the concrete, you need to choose a concrete adhesive that is suitable for it.

Floor Size or Coverage

Coverage means the floor area a specific amount of adhesive can cover. Usually, this information is stated in the packaging. You should buy as much adhesive as you need. But you shouldn't overlook the wastage - which is inevitable. A rule of thumb is 10%.

Gap Filling

The more gap-filling the concrete block adhesive, the stronger concrete you're going to get. Waterproof concrete is best in this regard because it binds most vigorously to stop water dispersion. This feature is all the more important for repair works.

Dispersion Method

To avoid arm fatigue, you should use spray cans. Be careful not to spray on unwanted surfaces. This problem can be solved by covering the adjacent areas with wrappers. You may also consider adhesives with nozzles.

Drying or Curing Time

Depending on the type of the job, such as ground-up construction or repair work, the curing time you can afford may vary. Durability is the priority in ground-up construction, whereas repair work is usually done in a relative hurry.

Other priorities, such as deadlines, waterproofing features, etc., are also to be considered. On average, polyurethane adhesives dry in 48 hours. Low-viscosity polyurethane cures faster, whereas high-viscosity ones require more time.

The epoxy may take 24 to 72 hours to cure. Thin-set adhesives dry in 12 hours or a little more.

Water and Temperature Resistance

The adhesive must be resistant to the corrosive effects of water and temperature. Especially in the exterior use of adhesives, you must keep in mind the rainy, snowy, or hot weather conditions the concrete must bear.

How to Use Concrete Adhesive?

By now, you've got the best adhesive for concrete. But how should you use it to get the most amazing experience? Well, we're about to discuss that in the following section.

Step One – Ensure Safety

Even though most of the adhesives on our list are VOC compliant, do use a mask. It never hurts. Wear gloves; otherwise, the glue may cause skin peeling. Precautions will allow you to avoid a range of future inconveniences.

Step Two - Surface Preparation

Clean all the loose chips, debris, and specks of dirt from the surface. You don't want these dislodged pieces or impurities to disconnect the bonding, thus making it defective.

Moreover, you should complete the cleaning before you prepare the concrete-adhesive mix. Because then the clock will be ticking!

Step Three - Preparation of the Glue

Make sure the ambient temperature of your workplace is suitable for the adhesive. Actually, it should be vice versa. Mix the concrete adhesive according to the manufacturer's instructions. Just before you apply the glue, shake the mixture again.

Step Four - Surface Alignment

Align the relevant surface carefully and support the project with nails, bolts, etc. Keep them steady till the adhesive dries up. Curing will take further time. You need to be extra careful to avoid the slightest misalignment.

Final Step - Cleaning

Clean the excess adhesive from the project. If it dries out, you may have to chisel the extra glue. In that case, you'll have to put in more effort and time. The process can even ruin the project. Usually, uncured adhesive can be whipped off by soap and water.

Frequently Asked Questions

1. Can concrete adhesive potentially damage the project?

Yes, it can. If you forget to clean up the extra adhesive before curing, you may have to chisel that apart. This process can damage your project. All you need is one misplaced hammer blow, and your work is ruined!

So, make sure to tend to the concrete adhesive before it cures. You can easily remove the uncured glue using just soap and water in most cases.

2. Which type of adhesive forms the strongest bonds?

In terms of sheer mechanical strength, Epoxy adhesives are the best. After the polymerization is down, they form extremely tough bonds with the substrate.

They come in two versions: single and double component paste. The former is the best alternative for welding. In fact, the J-B Weld Steel Reinforced Epoxy on our list is specifically named for this quality. This type of glues may require some heating before they're used.

The two-component version is also very prudent. Overall epoxy-based glues are heavy-duty adhesives.

3. Which kind of concrete glue is best for extreme climates?

Silicone is added to concrete adhesives to make them water-resistant. Silicone adhesives can withstand heavy rain, snow, constant soaking, etc. So, these constitute the most waterproof adhesives.

Silicone glues are resistant to high temperatures as well. Their general elemental resistance is very high, including UV rays. So, they are most suitable as outdoor adhesives and sealants.

4. If I need an inexpensive solution, what's the way to go?

Acrylic glues are less strong than their epoxy counterparts; they're not as waterproof as silicone adhesives either. But they've got one great quality: they are Cheap!

Stalin said, "Quantity is a Quality by Itself." And he was right on that. If you need to use a large amount of concrete adhesive, but you are not either able or willing to spend a fortune for it, the acrylic concrete adhesive can be the path to your salvation!

5. Any recommendations for basement use?

Basements can get really damp and moist. So, use the adhesives outdoors for basements as well. Use silicone-based adhesives. If you don't bother all that much about the basement, you may go for an acrylic one.

6. Can I decorate a concrete adhesive-covered wall with paintings? Which paint should I use?

Masonry paint, AKA elastomeric paint, is the best option for you. Oil-based paints will peel off with time; the same goes for acrylic ones.
