Resealing a concrete driveway using a solvent-based acrylic sealer typically involves the following steps:
- Clean the concrete driveway thoroughly to remove any dirt, debris, or stains. Use a pressure washer or a stiff brush and detergent to scrub the surface.
- Remove any stains. Remove oil with degreaser and pressure cleaning. Rust can be removed using CLR.
- Repair any cracks using an epoxy filler if necessary. Any potholes in the driveway using a concrete patching compound. Follow the instructions provided with the product.
2. Safety precautions:
- Work in a well-ventilated area and wear appropriate safety gear such as gloves, goggles, and a respirator mask to protect yourself from fumes.
- Ensure there are no open flames or ignition sources nearby, as solvent-based sealers are flammable.
3. Choosing the sealer:
- The easiest and cheapest sealer is a solvent-based acrylic sealer - suitable for concrete driveways. Read the product instructions to ensure it is compatible with your concrete surface and meets your desired finish (e.g., glossy or matte).
4. Applying the sealer:
- Begin by stirring the sealer thoroughly, following the manufacturer's instructions.
- Apply the sealer evenly using a brush, roller, or sprayer. Start at one end of the concrete driveway and work your way towards the other end.
- Make sure to apply a thin and consistent coat, avoiding pooling or excessive buildup. Multiple thin coats are generally better than one thick coat, as thick coats may result in an uneven finish or peeling.
- If using a sprayer, follow the manufacturer's guidelines for proper spraying techniques and equipment cleanup. Also mask up any walls using a protective tape if you are not confident of over-spray
5. Drying and curing:
- Allow the sealer to dry according to the manufacturer's instructions. Typically, it may take a few hours to dry to the touch.
- Avoid walking or driving on the driveway until the sealer has fully cured, which may take several days. Follow the manufacturer's recommendations for curing time.
6. Clean up:
- Clean the tools and equipment used for applying the sealer with an appropriate solvent, as recommended by the sealer manufacturer.
Remember to read and follow the specific instructions provided by the manufacturer of the sealer you choose, as different products may have variations in application techniques and drying times.
7. Adding colour to the sealer:
- Most solvent-based acrylic sealers allow the addition of colour to achieve a uniform or desired look. Follow the manufacturer's instructions for adding colour pigments to the sealer.
- Ensure that the colour pigments are specifically designed for use with the sealer you are using. Mix the pigments thoroughly into the sealer, following the recommended ratios, to achieve the desired colour.
