Select the right filler material

The right material is a critical factor in effective crack filling. There are different types of crack fillers in the market, each with advantages and disadvantages based on the type of crack and the type of surface being repaired. For instance, the best filler for hairline cracks in concrete floors may not be the best for large gaps along a wall. Epoxy fillers are ideal for deep and wide cracks, concrete crack sealants are better for narrow and shallow cracks on concrete surfaces, and sand-based fillers may work best for cracks in stone walls. Consult a professional for recommendations and choose a crack filler that is compatible with your surface and fits your budget.

Clean the surface

If you ignore this step, you will have trouble making the filler adhere to the surface, and the patchwork will not last long. The surface must be clean and free of debris, grease, and moisture. You can use a power washer, bristle brush, or scraper, depending on the surface and the type of crack. Remove any loose concrete, dirt, or peeling paint as well. Once clean, allow enough time for the surface to dry completely before applying the filler material.

Fill the crack correctly

Correct application is crucial to effective crack filling. You might be tempted to apply too much or too little filler in haste, but that can cause more problems down the road. You need to place the filler deep into the crack, ensuring that it fills the void completely. A putty knife or a trowel is ideal for spreading the crack filler. Remember to remove any excess filler by smoothly leveling the surface, leaving it flush with the surrounding surface. Allow the filler to dry completely, which may take a few hours or a day, depending on the type of filler and the size of the crack.

Seal the cracks

If you want the crack filling to last long, you need to seal it effectively. Sealing the cracks helps to prevent moisture, dirt, and other substances from infiltrating the surface and causing more damage. Some sealers are thin, acrylic-based coatings that can be sprayed or rolled on the surface. Others are more robust, epoxy-based sealers that are applied in a thick coating. Whichever sealer you choose, ensure that it is weather-resistant, compatible with the filler used, and suitable for the surface. Consult a professional for advice if you’re unsure about the right sealer for your surface.


Crack filling may seem like a small repair job, but if done wrong, it can lead to problems that are more complex and expensive to fix. These tips will help you make the right decisions when it comes to crack filling, ensuring that your property remains aesthetically pleasing, structurally sound, and safe for years to come.
