Protecting your patio: a guide to patio sealers
16th July 2026To ensure your patio stands the test of time and weathers the elements gracefully, understanding the importance of patio sealers is crucial. In this guide, we’ll delve into the world of patio maintenance, shedding light on aspects such as achieving a great wet-look finish and ensuring you get the right sandstone patio sealer. We also look at how to refresh paving that has already had treatment with paver sealer remover.
As one of the longest-running companies in the industry, we have a collection of tried and tested patio sealers that protect your patio from UV rays, rain and other environmental factors. This also includes making sure your jointing sand is not displaced when power washing.
Patio block sealer matt finish
For a look that effectively protects patio block but does not have such a treated look, many customers opt for a matt look. Our matt finish paving block sealer achieves an understated result that is focused on making your patio easy to maintain. It is only viable on clay block and concrete block paving but is a very popular choice among our customers who want a long-lasting professional finish.
Patio block sealer gloss finish
One of the most sought-after finishes for patios is the wet look (or gloss) because it intensifies the colours and textures of your paving stones, providing a stunning end result.
While there are many products out there, we provide the number one option for customers to achieve a long-lasting gloss effect with their patio. The gloss block patio sealer finish also effectively stops weeds growing through the cracks when applied with sand joints.
The result is a sleek and polished surface that makes a statement, turning ordinary paving stones into extraordinary focal points. Note that our stone sealer gloss finish product is designed for concrete blocks only.
Environmentally friendly paving sealer
We provide a unique solvent-free patio sealer suitable for most forms of concrete paving. It ensures an environmentally friendly and ecologically sustainable option for patio protection. It seals and protects to help prevent stains and weed growth in and has been used by leading businesses around the world to help them meet their goals around environmental protection.
This is one of our most flexible products and can be used with clay blocks, concrete blocks, concrete flags, concrete slabs and natural stone. It is also viable for indoor spaces but should not be applied around swimming pools.
Sandstone patio sealer: preserving your look
Sandstone and other natural stone patios are often great-looking options with a unique style, but they are susceptible to weathering and staining. If you have an area of sandstone paving that is not well covered then you may quickly find that the look changes and requires constant maintenance.
Our sandstone patio sealer is a specialised solution designed to penetrate deep into the stone, offering long-lasting protection. This sealer preserves the natural appeal of your sandstone patio, ensuring it remains a low-maintenance and visually stunning outdoor feature for years to come.
We provide a sandstone sealer colour enhancer and an invisible sandstone sealer option for our customers, depending on the look they want to achieve. Both are viable options for natural stone and help protect from both stains and algae growth. They also only require one coat for application.
Paver sealer remover: a fresh start for your patio
Change is inevitable, and when it’s time to refresh or alter your patio’s appearance, the Paver Sealer Remover becomes an invaluable tool. This solution allows you to safely and effectively strip away old or unwanted sealers from your pavers. It’s the first step towards a renewed and revitalised patio, ready for a fresh coat of sealant.
Our sealant remover is ready to use straight from the container and utilises safe, low-odour water-based technology to achieve the best result. It is viable when removing any paving sealer on any paved surface and restores the surface to its pre-paved condition.

Patio Sealer FAQS
Why should I seal my patio?
Sealing your patio protects the surface from rain, UV rays, stains and general wear, which keeps it looking better for longer and makes it far easier to maintain.
A good patio sealer also locks jointing sand in place, so it isn’t washed out when you pressure wash, and helps stop weeds growing through the joints. Without that protection, paving can fade, stain and loosen over time. Industry body Interpave publishes useful guidance on how block paving is laid and maintained, including the role jointing sand plays in keeping a paved surface stable.

What is the difference between a matt and gloss patio sealer?
A matt sealer protects your paving with a natural, understated finish, while a gloss sealer creates a “wet look” that intensifies the colour and texture of the paving.
The Resiblock Superior Natural Matt finish suits clay and concrete block paving and is a popular choice for a long-lasting, professional result that doesn’t look treated. The gloss option is designed for concrete blocks only and gives a sleek, polished surface. Both help stop weeds when applied with sand joints. For background on the different types of concrete and clay block paving, Interpave is a helpful independent resource.
If you can’t decide between finishes, order Resiblock samples (up to four) and test them on a small area of your patio before committing.
Is there an environmentally friendly patio sealer?
Yes. Solvent-free patio sealers protect paving without the solvents found in many traditional products, making them a more sustainable choice.
Resiblock PatioSeal Environmental helps prevent stains and weed growth and can be used on clay blocks, concrete blocks, concrete flags, concrete slabs and natural stone. It is also suitable for indoor spaces, although it should not be used around swimming pools. If you are comparing products, the HSE guidance on COSHH explains why reducing exposure to hazardous substances such as solvents matters.

How do I protect a sandstone patio?
Sandstone patios are best protected with a dedicated sandstone sealer that penetrates the stone, guarding against weathering, staining and algae growth.
Natural stone is porous, so unsealed sandstone can quickly change in appearance and need constant upkeep. Resiblock offers a sandstone sealer colour enhancer to bring out the natural tones and an invisible sandstone sealer that protects without altering the look. Both need only one coat. The Stone Federation Great Britain is a good source of wider information on caring for natural stone.
Before you start, check the Resiblock application guidelines so you get the best possible result from a single coat.
How do I remove old sealer from my patio?
You can strip old or unwanted sealer with a dedicated paving sealer remover, which returns the surface to its unsealed condition ready for a fresh coat.
Resiblock Paving Sealer Remover is ready to use straight from the container and uses low-odour, water-based technology. It works on any paving sealer and any paved surface, making it the first step if you want to change your patio’s finish or refresh a tired treatment.
For product specifications and safe handling details, download the Resiblock technical data sheets, or speak to Resiblock if you need advice on resealing afterwards.
How long does patio sealer last?
A high-quality patio sealer can last for several years, with Resiblock patio sealers lasting up to five years.
Lifespan depends on the product, the paving type, how well the surface was prepared and how much wear it gets. Cheaper sealers often break down faster under UV exposure and heavy rain, which means reapplying more often. Resiblock is the only paving sealer with a guarantee and has been used on over 100 million square metres of paving across three decades.
