Bring Your Patio Paving Back To Life With The Best Block Paving Sealers

Are you looking to expand your patio’s Indian sandstone lifespan? Do you want to give your driveway a stunning matt finish? Whatever type of surface you want to tackle, there are endless options that can bring new life to your pavers. DIYers enjoy using solvent solutions like deck stain, wood preservers and patio cleaners on their furniture, fences and outdoor surfaces. But, what do you do to prevent weed growth and give an elegant gloss finish to your slabs outside the house? Well, that’s where the best block paving sealers come in!

With our buying guide, you’ll be able to understand all the most important questions that consumers just like you want to know more about. Say goodbye to anything growing in your concrete block once and for all! 

What is a block paving sealer? 

These sealers are a solution that helps prevent stains, growth of weeds and give your slabs a fresh look. As years go by, block paving loses its jointing sand, causing the surface to sink or move from its initial position. Weeds begin to grow, and driveways start cracking. By using the sealer, you improve the paving’s lifetime without letting water sink inside. 

You can use a sprayer to apply the sealer, but we highly recommend going for a brush or roller due to the sealer’s thick viscosity. The distribution will also be more equal.

Why should you use a patio sealer? 

There are many benefits to using this sealer. A lot of people opt for these essential products as they have multiple advantages over an extended period. Let’s have a look at some of the most prominent reasons you should consider purchasing one. 

1. It blocks weed growth. 

When rain showers hit, many annoying weeds grow on your slabs that take over the entire surface. Moss and algae can be frustrating to deal with and require additional gardening efforts. To limit this, investing in a durable sealer will help you tackle plant life.

2. It helps resist dirt & debris. 

It’s normal that your paving comes into contact with dirt, debris and natural elements that can crack or damage the slabs. Applying a sealant coating can make the slabs more resistant and sturdy to prevent grime, lichen and grease.

3. It gives your paving a beautiful finish. 

Applying a sealant is also an aesthetically pleasing addition to your slabs. It creates a natural look that gives a stunning touch to your stone, concrete, or other surface types. Some sealers that give a wet finish will make the colours of your paving pop out as if you just put them in.  

4. It’s hard-wearing & lasts long. 

Sun exposure can be harmful to the paving’s appearance, durability and lifespan. Also, when you’re walking over your driveway, that can lead to fading, wear and tear and long-term damage. Even a single coating can go a long way to prevent additional headaches and extend the slabs’ lifetime. 

What to look for in a block paving sealer? 

Are you a newbie when it comes to block paving sealing? Want to learn more about the must-have features that your sealer should have? Don’t worry; we are here to help as we’ve included the top things to consider so that you purchase a high-quality one like a pro. 

1. Surface Type 

The first to consider is what surface type you’re working with so that you determine the right sealant for it. Manufacturers will say which surface type their sealer is suitable for to pick the correct one. That way, you can have peace of mind that you took all the steps for your surface’s protection. A tricky surface material is Indian stone, but manufacturers will say in the product description if they work with this material. 

2. Sealant Type 

The next question you have to ask yourself is what type of sealant are you going for? There are 3 types, polyurethane, acrylic and water-based. Polyurethane is the most premium and strongest of the three,  acrylic is a middle ground, and water-based is a temporary solution. Each is suitable for a specific surface type and has its benefits. We go more in-depth about them further below, so keep reading.

3. Coverage Area 

Do you have a small or large paving area that you want to cover? Depending on the surface coverage, there are different patio sealer sizes with a larger litre capacity. From small 1-litre products to large 25lt containers, viable solutions cover extended ranges and give you more coating applications. Remember that the manufacturer may exaggerate the numbers a bit, so, to be safe, purchase more than you need not to run short mid-application. 

4. Drying Time 

Check how long of a drying time the patio seal product you’re eyeing takes. Some are super-quick drying and ready to step on in just a few hours, but others may need days to fully dry. If you're in a rush to finish the job, this can make a big difference for you, so read the description in advance to avoid creating a mess on your driveway. 

5. Finish Quality 

Block paving sealers give your surfaces a unique finish. For a glossy look, some patio sealers can give you that finish with just a few applications. As a general idea, the more premium versions will offer more elegant results. 

What are the different types of block paving sealants?

There are three types of sealants, polyurethane and acrylic (both solvent-based and water-based ones. Let’s have a look at each and how you can use them. Each is fit for a specific job type. 


A polyurethane sealer is a popular type and a best-seller. It’s one of the most long-lasting & robust resins that you can use on your patio or block paving. They have excellent quality when locking in the sealer and have close to no chances of loosening. It’s a bit costlier than the other two, but its performance is unquestionable. 

The nice thing about them, though, is that they only need a single coat, so you won’t be going through the whole product that quickly. A common use of polyurethane sealers is in airport runways and paving as they work superbly when locking in concrete.


Many prefer them as a softer concrete sealer. You can find affordable options that are not as expensive as polyurethane. Their most popular use is for pattern-imprinted concrete and for slabs. Unlike polyurethane, you will have to apply more than a single coat with these.


A water-based sealer is the most eco-friendly option as they work with zero glue. They are also the most inexpensive of the three types. The one drawback to this type is that it offers the least adhesive quality than the other two. Since it’s not solvent-based, we recommend using it as a temporary solution

4 Tips on when you should be sealing your block paving 

Are you just starting with sealing? Do you want some pro tips that will help you get started in no time? We’ve added our recommendations and suggestions that will give you the best quality results! 

  1. Before you do anything, make sure you power wash dirt & debris away with a pressure washer. 
  2. Let your paving set for at least 8 weeks to enjoy optimum results.
  3. Within this period, you can spot problems such as staining, wobbling and bad water drainage.
  4. Allow efflorescence (surface whiteness) to fade away to avoid build-up.
  5. Apply the sealer after the efflorescence has faded so that it doesn’t lock in. 

How many sealer coats should you apply? 

Depending on what product you pick, the coating application will be different. The final look will also vary. In general, polyurethane requires a single coating due to its superior adhesive strength. Acrylic sealers give you the best result and protection with two coatings. Water-based solvents may even need three or more applications. Keep in mind that a single coat will give you a matte finish, whereas two or three coats will result in a soaked look.  

Is there a chance of slipping on a driveway sealer? 

No, as long as you follow the manufacturer's instructions, there is no risk of injuring yourself after an application. We understand you may think that sealing the paving can make the surface slippery; but, the chances of that happening are close to zero, provided you correctly coat the driveway. 

Can you seal on top of other sealants? 

You may seal over other sealants, but this depends on the surface you want to apply it on and the manufacturer's recommendation. For example, you can apply other sealers over Resiblock, provided that the previous one was silicone-based.  Each product will have its own unique instructions. However, one thing to remember is that you should wait until the previous sealer has fully dried up so that the next one can effectively lock in. 

What should you use as a concrete sealer? 

When you first install a concrete slab, the contractor may suggest that you seal it for longevity. Sealing your concrete is a necessary step to fight back water drainage, deicing salt and oil stains. The best sealant for concrete is a solvent-based sealer. They are affordable and fit for residential use. By applying the sealer, you protect your surfaces and make them more resistant to spalling, cracking and pitting. For best results, spray the first coating and then roll the second coat. 

How many litres do you need for home use?

The answer depends from one manufacturer to the other. Some handy online calculators can help you calculate how much block paving sealer you may need. One thing to always remember is that you shouldn't compromise on the quantity because you will then compromise on the quality too. Purchase enough sealer so that it will be fully soaked, not just scraped over. 

A general guideline is that around 1 litre of a product will get you through 2 square meters. A 5-litre container can roughly cover from 10 to 15 square meters of your backyard, while the larger ones from 20-25 litres can handle up to 50 square meters.

How much do block paving sealants cost? 

Block paving sealers are a DIYers must-have when handling surfaces. They come in various sizes and for different surface types, from affordable to high-end options.


The most inexpensive ones start from as little as £16.69 to £70. These will be smaller in litre capacity and work on specific types of surfaces. Those on a tight budget will enjoy using these on their block paving, and they may be water-based


The premium models will start from £80 to over £120. They have a larger litre capacity, broader area coverage and may be suitable for all surface types. If you can up the price for these, you will benefit from algae and moss reducing formulas, a more attractive finishing look and high-quality polyurethane solvent-based sealants.
