Types of Patio Sealer 

By far the first thing that you need to know about is the different types of patio sealer, as they aren’t all going to be compatible with your patio. If you are wanting to get the best seal and best protection for your patio then you are going to need a compatible patio sealer…

  • Block paving sealer – This is decided specifically to be used on block paving as it comes with additional colour enhancing properties to really make the colour of your block paving stand out! Not only this, but they will have features to help fill holes in joints, therefore preventing weed growth. This will also encourage stability in your joints and patio as a whole. 
  • Driveway sealers – It’s obvious that driveway patios are going to have to take a lot of weight and movement on a daily basis, which is why you will regularly find loose and moving patio slabs! However, a driveway sealer is designed to stabilize the sand in your joints to reduce movement as much as possible. Not only this, but it will provide a protection for the paving slabs to reduce discolouration and marking from the tyres or your car. 
  • Stone Sealer – Any type of natural stone, such as slate or indian sandstone, is going to need a more specific sealer that is designed to work with the natural materials. Using a non-specific sealant on these models could cause real damage to your stone. Always opt for a natural stone sealer in these circumstances and check whether it is compatible with your type of stone.


The next thing that you need to look at is the coverage that you are going to achieve with your bottle of patio cleaner. This will be determined by the size of tub that it comes in (obviously) but also how concentrated the solution is! The sizes of tubs range quite considerably from as little as 5L up to around 30L, so if you are buying a bigger tub make sure that your patio sealer has a long expiration date if you are not planning on using it all in one go! 

You also want to look at whether your patio sealer is going to need one coat or two coats as this will obviously affect how much solution you are going to need to purchase. Many are going to need two coats – the first to soak the sand and the second to fully seal. However, some will actually do more harm than good if you apply two coats, so this is definitely worth checking out before you buy. 

The best patio sealers that we found offered around two metre square coverage per litre of sealer, which gives you a good idea of how much you are going to need! 


Make sure to check how durable and long lasting your patio sealer is going to be. You don’t want a patio sealer that you are having to redo every few months otherwise this totally defeats the object of ensuring your drive is protected and well maintained. Some are going to last for even a couple of years before needing replacing (providing you complete general cleaning and maintenance in between). 

We particularly like patio sealers that are going to have mould preventing features. These will “clog up” and seal the pores in your patio whether it be natural stone or concrete slabs and provide an almost wipeable material which will help to prevent mould from setting on your patio.

The Best Patio Sealers 

Hopefully by now you know the type of patio sealer that you need to look out for and the ones that are going to be compatible with your patio. But, there are so many other aspects to consider before you buy as well! 

  • Drying Time – Living in the UK means that you definitely need to consider the drying time of your patio sealer. Some will be dry and sealed within the hour, which means that you aren’t having to juggle completing your job around the weather too much. Others take considerably longer which can be an inconvenience not just with the weather but if you have pets or the sealer is being used on a driveway.
  • Application – It is always worth looking whether your patio sealer comes with anything to help the application process. Some patio sealers come with rollers or brushes to make it easier to apply to your patio! Others can be used with a standard paint sprayer but obviously these won’t be included!
  • Matt or wet look finish – You will need to decide whether you are wanting a matt or a wet look finish for your patio sealer. A wet look is going to be much shinier and arguably easier to keep clean but a matt finish will look more natural.
  • Colour Enhancement – Some of you would probably like the idea of having a colour enhancement on your patio, it is a great way to really make your patio stand out and become the envy of your neighbours. However, this is going to stop your patio from looking as natural and blending in with the rest of your garden or the frontage of your home. This is something that really comes down to personal preference and the style of your garden/home. 
  • Non toxic – If you have pets or young children then we would definitely recommend checking that your patio sealer is non-toxic. Although really you are going to need to keep them off your patio anyway until it has dried, you’re better just not taking any risks! 
  • Additional surface grip – If your path, patio or driveway is on an incline and is causing you some problems when wet or icy then look out for patio sealers that are going to increase surface grip!

How To Apply A Patio Sealer

If you have chosen your patio sealer and are ready to start applying then we are here to help. Here is a video from our “best pick” patio sealer manufacturer with everything that you need to know before you start applying the product.

Frequently Asked Questions

Can you use a pressure washer on a patio that has been patio sealed?

We probably wouldn’t recommend using a pressure washer on a patio that has been sealed. Whenever you use a pressure washer on a patio you are potentially going to be removing bits of sand or jointing compound from the gaps in between your flags. Doing this is obviously going to not only damage the overall stability of your patio but also remove the patio sealer from that area leaving you having to reapply the sealer. Not only this, but that could lead to a patchy job as in some areas you will have two layers and in others you will have just one. 

How do you apply patio sealer? 

Applying most domestic patio sealers is relatively easy – some will even come with a brush or a roller to help you on the way. Simply “paint” your patio sealer onto the patio and the joints and wait for it to dry. Remember that all patios and patio sealers are going to be slightly different, so you need to check the manufacturer’s instructions and may need to consider applying two coats! 

How long will a patio sealer last?

Depending on the patio sealers they will normally last around a couple of years at least before they are ready to be resealed. Some will need to be resealed more regularly in well used areas whereas others will last up to 5 years!
