Concrete Driveway Crack Filler Buying Guide

Concrete Driveway Crack Filler

Not every crack filler you see in the market is suitable for your intended use. Some might be good for thinner cracks, while some others might cover up wider cracks in one go.

Some fillers come in the pre-mixed form, and some others don’t. How do you know which will serve your purpose best?

Let us walk you through the wide lane of concrete crack fillers and help you choose the best concrete crack filler available. Here you go –

Crack Size

As filling a crack is the main target of buying concrete crack fillers, it is always better to measure the size of the cracks before you head to buy a filler. It is because almost all the fillers are made to repair certain sizes of cracks.

If the filler you buy doesn’t match with the crack, it will be nothing but a waste of your hard-earned money.

Some fillers can handle bigger cracks, but often they need multiple applications. Also, check for that in the specification before you buy.

Mixing Method

You will see two types of concrete fillers depending on their formulation. Many concrete crack fillers in the market come pre-mixed, meaning you can use them right out of the box. They are all ready to be applied on the instructed surface without any further due.

In the case of these fillers, you don’t need any special knowledge about mixing the components or extra time for preparation.

Most of these fillers are water-based. Using pre-mixed fillers is a good idea for beginners as it requires less or zero hassle.

On the other hand, non-premixed fillers are usually shipped as separate components. Once you get the compounds, you need to mix them together following the instruction. The right proportion should be maintained to gain the right effectiveness from the filler.

These fillers might be a bit more technical. But you will get a better result in most of the cases. Also, these fillers need less curing time than their pre-mixed counterparts.

Curing Time

This is often the headache of people who want to work with concrete fillers. Waiting a long time for the concrete filler to cure is very boring. But you also might not want to damage the repaired crack by hitting the patches before a certain time.

Usually, water-based products take a lot longer to completely cure and be ready to use. The curing time might be about 24 hours before you will be able to step on the surface if it is outdoor.

But in the case of epoxy-based or latex-based products, the curing time is very low. Most epoxy-based fillers completely cure in only 6 to 8 hours, where latex-based products dry and harden in 20 to 30 minutes.

So, determine how much time you want to spend after the cracks and choose your filler accordingly.


Some concrete fillers are discretely made for indoor use. But many other fillers are made to use both outdoor and indoor.

In case of outdoor use, the finished patches often face harsh weather conditions. Also, concrete tends to expand and contract depending on the weather.

So, if the filler you are buying doesn’t have enough flexibility to match that of the concrete, it is most like to crack again. Make sure the concrete crack filler you are buying has enough flexibility and weather resistance.


Moisture is one hell of an enemy to concrete. The fillers we use in places close to water are at more risk of moisture being penetrated.

So, you need to check out for a filler that is completely waterproof and lets no moisture sneak into the structure.

This is the only way to keep your structure safe for a longer period. And it will also lessen a lot of hassle. Be careful while you choose the crack filler so that you don’t need to repent later.


Concrete patches need to be durable. The crack you are repairing should be the last time you work on it.

If the patches start to break and crack, then what is the point of using them in the first place? Always look for a crack filler that is highly durable and can withstand all pressure for years.

Ease of Use

Don’t neglect this factor while choosing a concrete crack filler. If you have never worked with a crack filler, you might not want to add hassle by choosing a high-tech filler. Rather choose something simple to use and effectively serves your purpose.

Often, liquid or pre-mixed fillers are the best for beginners as they don’t need any special knowledge or tool to work with. They also provide enough strength to stick to the concrete.
