Concrete Driveways: Three Crucial Guidelines on Sealing Your Surface
Posted on: 28 November 2017
Concrete sealing will prolong the lifespan of your driveway and preserve the aesthetic appeal. In simple terms, concrete surfaces experience degradation due to exposure to adverse outdoor conditions. When a sealer is applied, it will limit the porosity of the structure. As a result, your driveway will not experience cracking due to freeze-thaw cycles. Also, the surface will be invulnerable to damage by oils, stains and dirt. However, it is essential to note that the benefits derived through sealing the surface will depend on the integrity of the coating. Therefore, consider using the below guidelines to ensure that the sealing process is successful:
Prepare the Concrete Surface
Proper preparation of the concrete surface is essential before the application of the sealer. One of the common reasons for sealing failures is poor clean-up of the driveway. If the concrete is covered with dust, oil and other materials, the coating will not adhere to the base. Within a limited duration, delamination or cracking of the exterior layer will occur. For the best results, you should check the manufacturer's recommendations on surface preparation. In general, it is advisable to remove all previous sealers and scrub the surface before proceeding. Some sealer manufacturers also recommend surface etching for maximum coating adhesion.
Time Your Project Appropriately
You should be careful when choosing the timeline for your concrete sealing project. Poor planning can lead to unexpected complications and subsequent failures. Ideally, you should perform the process on a day with fair weather. The sun will allow the sealer to cure fast. If the weather patterns are unpredictable, you should hold off on the project. After applying the coating, you will need to allow time for the layer to dry. You should not expose the roadway to traffic during this period. If you are planning on sealing a new concrete driveway, you should allow the surface to cure and stabilise before proceeding with your plans. If the material is not entirely settled, the sealer coating will experience stress and fall apart.
Apply Thin Sealer Coatings
Finally, you should ensure that you have achieved optimal coverage during the sealing project. You can choose to roll or spray the coating, depending on your preferences. Ensure that the entire driveway is coated appropriately to prevent porosity in some areas. When applying the sealer, you should always use thin layers to minimise uneven bumps. For instance, choose two thin coatings instead of a single thick one. This practice will ensure optimal sealing and maximum aesthetic appeal.
