Patio sealer and block paving sealer are designed for different types of paving, so choosing the right product for the surface is important.
Although both are used to protect outdoor paving, the construction, material and jointing between the paving can all affect which sealer is most suitable.
Here at Swiss Seal, we always recommend checking what type of paving you have before reaching for the sealer. Using the wrong product can affect the appearance of the surface and may not give you the protection you were hoping for.
What is patio sealer used for?
Patio sealer is designed to protect suitable patio surfaces from everyday dirt, staining and weathering.
The type of patio makes a difference, though. Natural stone such as sandstone, limestone or slate can have very different characteristics from concrete paving, so you should always check that the sealer is suitable for the particular material.
A good patio sealer can help reduce water and dirt penetration, making the surface easier to maintain while helping it stay looking its best.
Some products can also enhance the natural colour of paving, while others provide a more natural-looking finish.
What is block paving sealer used for?
Block paving sealer is specifically formulated with block-paved surfaces in mind.
Unlike a solid patio slab, block paving is made up of individual blocks with joints between them. These joints contain sand and can be particularly vulnerable to weeds, dirt and moisture.
A suitable block paving sealer can help protect the blocks and reduce the amount of moisture and dirt getting into the surface. It can also help stabilise jointing sand, depending on the product used.
This is one reason why choosing a dedicated block paving sealer can be preferable to simply using a general patio product.
Can you use patio sealer on block paving?
Not necessarily. The product needs to be suitable for the specific surface and construction of your paving.
The terms patio sealer and paving sealer are sometimes used quite loosely, which can make things confusing. What matters is the manufacturer's recommended use.
Always check the product information before applying a sealer to block paving. If it has been designed for natural stone, for example, that does not automatically mean it is suitable for concrete block paving.
The same applies in reverse. A product intended specifically for block paving may not be the right choice for a particular natural stone patio.
What should you consider when choosing a paving sealer?
Think about the material, the condition of the paving and the finish you want to achieve.
For block paving, consider whether you want protection against staining, a particular appearance or help with maintaining the jointing sand. For patios, make sure the sealer is compatible with the specific type of stone or paving.
The best paving sealer UK homeowners can use is not simply the strongest one - it is the one suited to the surface.
At Swiss Seal, we believe good preparation and the right product go hand in hand. Clean the paving thoroughly, allow it to dry properly and make sure the sealer is designed for the surface you're working with.
Get those basics right and you're giving your paving a much better chance of looking good and staying protected for longer.
