How to Use Patio Sealer
If you own a flagstone patio then you probably want to treat it with a good patio sealer. This product ensures the long-term durability of the flagstones while minimising maintenance, making it a worthwhile investment for anyone looking to maintain their patio paving.
Preparing the Patio
Before you apply the sealant, it is important to prepare the patio area to ensure the best results possible. Basically, you want to give the patio area a thorough clean, removing debris and washing the surface to kill off any growth like algae or mould.
Be sure to sweep the entire area, removing loose debris such as leaves, stones, sticks etc. A hard-bristled brush is recommended for this as it will sweep up fine material and is great for removing dried in soil.
Consider cleaning the patio with a good patio cleaning solution. These are easy to use, basically requiring you to combine with water and rinse over the patio surface. This should remove all dirt, grime, and natural growth.
Give the grouting a once over to determine if any repairs are needed. This task is much easier to complete before sealing, so make sure to check the overall condition of the patio.
While most products are not acidic so won’t cause too much damage, they do tend to have powerful cleaning solutions that will irritate skin upon contact. Therefore, you will want to make sure you have suitable protective gear to remain safe while applying the sealant.
Recommended personal protective equipment for applying sealant include:
- Respirator mask (important if using a sprayer application)
Also, because many products are not diluted with water there may be a risk from contacting residual liquid. So, once you apply the sealer across the patio make sure to let it dry for the recommended time before applying another coat.
Testing an Area
While the solution will protect your patio it is important to remember that it may cause some changes to its appearance, although this is never guaranteed. However, to ensure you know what to expect from the result, consider applying a test area sample on a small portion of the patio, preferably somewhere inconspicuous in case you don’t like the results!
To test an area do the following:
- Apply a small amount of sealer to a corner of one the patio stones
- Allow the sealant time to properly dry before applying a second coat
- Inspect the result after a few coats to see if it looks okay. If you are happy with the results then it is time to apply to remainder of the patio.
Sealing the Patio
Once you are happy with the testing area then you are ready to apply the sealant to the entire patio. Make sure to follow the manufacturer guidelines on the label to ensure you are doing everything correctly. You will likely apply it using a roller or sprayer, so be sure to check the instructions in case you need to buy an applicator.
Here are some tips to remember when sealing a patio:
Consider the weather conditions leading up to the sealing – rain and wind can both cause disruption so it is best to leave it for a calm and dry day, preferably during spring or summer.
Be mindful of plants, flowers, lawns, and bushes near the hard surface you are sealing. Anything too close may get accidentally covered in sealant, especially if using a sprayer, which can possibly kill the plant. If it does get on a plant make sure to quickly rinse your garden hose.
Keep pets and children far away from the surface area when sealing and until it is fully cured. Anyone touching it may cause irritation and will lead to an uneven surface.
