This article outlines how to apply sealant to your paving. Sealant helps protect and improve the look of your driveway and patio, there are a wide variety to choose from depending on the type of hard surface you would like to seal, your price, the finish you would like and the longevity. These sealants also will need renewing after several years, as their protective layer gets worn away.

What is sealant?

Sealants are specially designed chemical compound made to protect hard surfaces such as patios, driveways, paths, natural stone, concrete, and brick.

Why seal?

Over time hard surfaces are prone to the effects of the elements and general wear. This includes water and the freezing and thawing of water during the seasons. Natural and man-made oils on the surfaces, penetrating and discolouring the stone. Sunlight can also discolour from UV rays and dry the stones causing some wear, although a lot of stones in recent years are UV resistant. Cars also cause major wear and tear to driveways, as they are heavy and rubber from the tyres can discolour and crack the driveway and pointing.

Different types of sealant

There are three main types of sealants for your driveway, patio, and hard surface needs. This includes water-based sealant, solvent based polyurethane sealant and, solvent based acrylic sealants; each has their own use cases. Also, within each type of sealant there are many different products to choose from. You can also choose the type of finish you would prefer.

How to apply sealant to paving

Once you’ve decided to apply a sealant to your paving or hard surface, ensure it is adequately cleaned and dry. The next decision is to choose the moist suitable way to apply the sealant. Please see our guide on cleaning hard surfaces if your surface is still dirty.

If you are applying sealant as a one-off a roller and try from your local hardware shop will suffice. If you plan to apply sealer regularly a great investment would be a sprayer, also a moisture meter is a good investment. Another key comment to mention is to ensure that there will be no rain 24 hours after applying the sealant, as the moisture will disrupt the finish off the sealant. The step to step guide is as follows:

  1. Choose the most suitable sealant for your needs, using our guide.
  2. Read the manufacturers instructions and guidance before starting the sealing process.
  3. Acquire and wear suitable PPE including, overalls, suitable footwear, gloves, eye protection, and solvent respiratory mask.
  4. Spend a suitable amount of time applying and planning your seal.
  5. Apply a test coat on a inconspicuous area of the patio or driveway. Ensure you are happy with how it looks because results may differ.
  6.  Apply the sealant at the corner edge of your driveway, then work outwards.
  7. Work in a straight line across the paving, ensuring not to block the supply of sealer or where you have to walk on the sealer.
  8. Apply the sealant until the surface is saturated with sealer. This allows adequate coating and and sand in the joints to absorb the sealant if applicable. Although, ensure not to pool any of sealant.
  9. Continue applying an even coat of paving sealer to the whole area.
  10. It is advisable a second coat of sealant is applied. Once the first coat is dried; after approximately 4 hours. Redo the process from step 4. This ensures adequate protection and that no area of paving has been missed.
  11. Ensure there is no traffic on the freshly sealant paving, for at least 4 hours for foot traffic and 24 hours for vehicles. This ensures the sealant has enough time to settle.
  12. Final step is to enjoy your freshly cleaned paving. Remember to clean regularly.
