5 Best Patio Sealers of 2025

Offering good value for money, this Everbuild 405 Path & Patio Seal comes with enough product to coat a large patio at least twice (if not three times).

The 25 L bottle of solvent-free, acrylic coating is very reasonably priced considering its coverage, and it creates a good finish on the patio.

As long as the patio is thoroughly dry and clean of debris before application, it can produce a non-slip, low-sheen finish which protects the slabs from water, stains and wear. The exact area that one bottle can cover is dependent on the porosity of the patio and how the seal is applied.

The liquid has a low enough viscosity to apply with a paint/fence sprayer, which seems to produce better results compared to using a roller. Using a sprayer is also more economical in terms of product usage. At least two, if not three coats will be required, and it takes at least three hours before the next coat can be applied.

To make things easier, the seal has a slightly milky colour when wet, which makes it possible to see which areas have already been covered. One 25 L bottle should be sufficient for the majority of spaces.

Everbuild state that this seal can be used over patios, paths, concrete and block paving.  The instructions also say that the seal can be applied on damp slabs, but this may produce a patchy appearance so it’s best used when they’re completely dry.

Overall, this patio seal creates a quality finish on the patio, and it’s one of the best patio sealers in terms of value for money. The effect isn’t as shiny as some solvent-based sealants, but it protects slabs against stains, UV rays and water damage. Plus, it won’t kill the grass if it accidentally comes into contact with it.

With an included fungicide, the Sika Patio Seal is one of the best patio sealers for protecting the patio and stopping any slippery moulds grow over the colder months.

If your patio is prone to attacks from green mould and algae, perhaps because it’s positioned in the shade or you live in a damp area, this seal can help prevent excessive build up.

The water-based acrylic coating can be used on paths, patios, natural stone and concrete, protecting the surfaces from rain, oil, sun and organic growth. It gives quite a glossy finish, especially when two or three coats are applied. However, if your patio is quite porous, you may find that with just one coat it’s still relatively matt.

The 5 L container is sufficient to cover an area of approximately 40 m² (with one coat), although this also varies depending on the porosity of the stones. It’s quite a runny liquid, and a lot can go a long way. It can be applied with either a sprayer, brush or roller, with a sprayer generally being the most economical method. Approximately two hours are needed between coats.

Once dried, the Sika Patio Seal is very resistant to water, and it brings out the colour of slabs with its slightly glossy finish. The sealer is sufficiently high-gloss to shimmer in the sunlight, which may or may not be desirable depending on personal preference.

The patio also becomes much easier to clean after using the seal, and dirt like bird dropping are much easier to remove simply with water and a soft brush.

If you want to avoid a gloss finish, the Pro-Kleen PatioSeal dries matt, leaving almost no trace on the paving at all.

Whereas the majority of sealers leave a mid to high-gloss finish, the Pro-Kleen PatioSeal barely alters the appearance of the stones. This makes it one of the best patio sealers on the market if you want to achieve a matt look on your patio.

It comes as 2 x 5 L bottles, which, according to the manufacturer, is sufficient to cover 100 m² (each bottle covers 50 m²). However, in reality it is unlikely to achieve such expansive coverage.

Customers report that using a fine sprayer is the best way to apply this seal, in order for it to give the best finish and be economical with the product. Drips and splashes will result in uneven coverage, so care needs to be taken to apply it evenly.

PatioSeal creates a layer over the stones that makes them easier to clean, and it can help repel dirt, water, and oil. If you like to have BBQs on your patio during summer, but hate the messy grease stains that they leave behind, the surface should get much fewer stains after applying this sealer.

It dries quickly, becoming rain-fast after three/four hours and completely cured after approximately twenty-four.

Although PatioSeal is suitable for Indian sandstone, patios, paths, concrete and brickwork, it shouldn’t be used on lime-based materials.

Suitable for use on both interior and exterior surfaces, this Black Diamond Stoneworks Wet Look Stone Sealer creates a natural wet-look finish and brings out the original colour of the stonework.

It can be used in bathrooms and kitchens with stone or slate floors, as well as on concrete, slate, patios and other porous surfaces. The finished effect looks as though the stone is damp, which brings out richer tones and colours.

A single coat may be sufficient for some uses indoors, but for the most part at least two (if not three) coats will be required. The more coats that are used, the glossier the finish. It can be applied with either a roller, brush or sprayer, and the liquid has a reasonably low viscosity.

During application, the acrylic-based sealer shouldn’t be allowed to pool, as this can lead to white spots and marks remaining visible once it dries. If spraying on an uneven surface, it can be more difficult to ensure no puddles form, and a brush may be required as well as a sprayer.

Although the majority of sealers featured on this page are fast-drying, the Stoneworks Wet Look Stone Sealer is particular quick, and a second coat can be applied after just one hour.

The 3.785 L (1 gallon) bottle contains enough sealer to do a couple of coats on the majority of small/medium patios, but a larger amount may be required for bigger areas.

Given that it can be used for both interior and exterior surfaces, and has a low odour that isn’t overwhelming inside, this is one of the best patio sealers for both indoor and outdoor use. If you have any stonework that is looking a little dull, this can brighten it up. It’s also particularly effective on darker colours.

One of the best sealants to buy on a budget, the Bond It Patio Paving Sealer comes in a 5 L bottle and brings out the natural colour of paving stones without breaking the bank.

Compared to some other makes, it’s markedly less expensive, especially considering that you still receive a reasonable amount in the bottle.

As a solvent-free, acrylic based formula, the sealer has a limited odour and is relatively easy to apply. It can be used over many different patio surfaces including sandstone, limestone and concrete. On most surfaces, it dries to a clear and subtle matt sheen finish with limited gloss.

Application can be done with a paintbrush or roller, and it spreads on easily. As with the majority of these products, if the sealer is allowed to pool during application, it will leave white marks when it rains – so beware!

The Bond It Patio Paving Sealer is also relatively effective against the growth of mould and algae. Although it may not stop it from growing altogether, customers have reported noticing a dramatic decrease in the amount of mould present on their patio.

It creates a good seal against rain and water damage, and can also protect the patio or driveway from oil and petrol marks.
