very good product ,a bit uncertain which to buy as there are several sealing products of this type, this has turned out very well and are very pleased with final finish, very helpful videos and advice from this company and would certainly try more of their products,

By Allen John Herbert

Thank you SmartSeal for a great product and for the ready help both by phone and video to guide me through the process. On the advice of my contractor, I had left my new block paving for a year to ensure that any efflorescence had washed out. My drive slopes down towards the house quite steeply and the main, but not unexpected, problem was that sand between the blocks was washing out and blocking the drain outside the front door in heavy rain. I manged to get the block paving sealer on at the end of last month in one of the few dry periods. Since then it has been well and truly tested and the sealer has solved this problem completely. At just over 200m2, this was quite a big project and I must confess to having been a little apprehensive about taking it on myself but, with all your help and guidance, I need not have worried. Given the size of the task, the sprayer was also a very worthwhile investment. We are delighted with the result which not only leaves the drains clear, but looks stunning as well. As an added advantage, the ants have also given up their excavations!

I have been using Smart Seal block paving sealer and patio sealer at my own property for Four years. Every spring I reseal my drive and flags. After doing so it all looks like it was laid yesterday! Great product and good advice ! I wont go anywhere else!

By Steve Duckworth From Blackpool

Very pleased with purchase of block paving sealer. Followed detailed guide on site to prepare and applied with pressure sprayer. Simple and fast application.

By Peter Bull From Redditch

This is the first time I have used this product and I am very impressed. I 2 coated a recently installed Brett Beta driveway and it looks superb with the colour enhancing. The sandstone sealer is also of the highest quality.

By John Wheeler

Just did my annual reseal of drive, every time I do it I am freshly reminded of how brilliant this product is!! Thank you.

By Mark Wolves From Wombourne

We used this on our new drive a few years ago and it looked great. Had an accident recently with petrol spillage which stripped some of our drive, it looked awful! Found a left over tub of this and cleaned and resealed it, cannot believe how fantastic it looks again! Would highly recommend this product!

By alan rooksby From mansfield Notts.

Order for block paving sealer arrived on time top quality, it does what it says on the tin ,

By EDDIE From Manchester

Excellent product. Easy to apply and makes the driveway look like new.

By Neil From Somerset

Great product, prompt delivery and excellent service. Recommended. A+++

By Barry Fisher From Warrington

Very good product and brings up the look of the drive very nicely. Next time I would use a roller, I used the sprayer and even though it was from Smartseal it was quite 'gloopy' coming out of the nozzle due to the viscosity of the sealer. Other than that no complaints and also very good service from Smartseal.

By VinCae Salvati From Middlesbrough

Excellent product, 1st class service and delivery, highly recommended.

By Mal Evans From Stafford

Just sealed my drive whilst the weather has given me the opportunity. Must say that I am very impressed with the result as the drive looks first class & is as good new. Would definitely recommend the product. I would like to mention that I was very impressed to receive the product within 24 hours of ordering considering I did not ask for a special delivery!! Once again many thanks.

By Cyril Jackson From Rotherham

Brand new block paving to my drive, sadly the night the guys finished laying the paving we had a massive thunder and rain storm through the night resulting in efflorescence on most of the paving bricks, used Smartseal Efflorescence Cleaner with excellent results, I did have to re-apply one area but that was fine afterwards. Sealed the paving after a suitable period, I found using a watering can (disposable) and a roller the best option, the Smartseal video is a bit miss leading seeing the guy use a squeegee (I bought one to use) but found that I would have used twice as much sealer, however I did find the Marshall bricks used were quite open pored so they drank the sealer. Final comment, we are very pleased the finish looks fantastic.

By Philip From Bedfordshire

Tip top product - swift delivery and text in advance too... Easy to apply and drive looks fab - a little bit shiny without being full wet look! Have had several comments about how great it looks! Highly recommend this product - I will be using again when the time comes :)

Smartseal Blocking Paving , have been offered other Sealer which I been told is cheaper. But I would not risk it as Smartseal sealer is the best on the market in my opinion. And the back up service from the team at Smartseal is 1St Class.

By Keith Wenham From Premier Drive Clean

I was forewarned about using the product when there is rain about and it was almost 2 months before I applied the first coat. The sprayer supplied was unfit for purpose and this didn't help. Didn't apply enough on the first coat as it is difficult to gauge how much is being used and was wary about not having enough for a second coat. Applied a second coat which made a big difference and eventually a thin third coat. Still had some whiteness which is supposedly caused by moisture but it was always bone dry when I used it. Just back from a 2 week holiday and the colour has lightened. Still looks good but the proof of the pudding will be next Spring after a harsh winter.

By Neil Colville From Blairgowrie

5 Star service for all aspects. Application, finish, prompt delivery, slick transaction.........also, a very kind understanding during our chat about the very wet Summer we've had this year.

By danny From Fife

Excellent Product, friendly and polite people to deal with.

By Barry Hake From Sheerness Kent

Smartseal's service and customer care is every bit as good as their products. As a professional business, we need top quality products to match our high standard of work. The sealant is easy to apply and provides a great finish. We will be using this excellent sealant with our customers for years to come.

By Steve Williams From S. K. Williams Property Cleaning Services

This company provide good service and the products do a great job, its down to you to get the best results by doing the prep work thoroughly ,on older blocks you will need really 3 coats if they have never been sealed can work out expensive but the results are worth the extra coat or that extra drum you will then have a driveway as good as new and be the envy of your neighbours,dont just sweep sand back in it needs wacking and brushing several times the results will be worth the extra time you spend doing all that prep work .

By claudio From cambridge

Placed my order and forgot to order Paving Sealant..... was contacted by SmartSeal Agent to confirm my original order... who they asked me if I required the Paving Sealant, I realised I had forgot to order it!! This was no problem the Agent (Nigel) sorted it out and added it to me original order. All was delivered intact and undamaged within a few days and no extra delivery cost to N.Ireland!! Very impressed with this company's customer service, I would recommend and use again.

By chris From www.northwesdtriveclean.co.uk

I received the order today - a very quick delivery. Smartseal rang me just after I made the on-line order to check that I had ordered the right stuff (which I hadn’t) and pointed me in the right direction. Thank you both for your vigilance and for an excellent service. I would have no hesitation in recommending Smartseal.

By Alan Hepple From Tyne & Wear

First class service - product arrived next day as arranged. Product gave a very good appearance to block paving. On the face of things looks very good but it's only been sealed for a couple of weeks and therefore its probably too early to give any definitive review at this time. Will be interested to see how its standing up at the end of the summer

By Walter Scott

Step-by-Step Video Guide

Solvent Based Acrylic Block Paving Sealer in Silk finish

Silk finish block paving sealer to create a slight sheen on block paved surfaces

Smartseal Block Paving Sealer (Silk) has been developed to enhance the colour and aesthetic appeal of new or mature block paving and to give longer lifespan and better overall protection.


  • High viscosity (silk finish) sealer for final coat to block paving
  • Easy to apply by sprayer or roller
  • Resists oil and stain penetration
  • Additional resistance to weed and algae growth
  • BS5750/ISO9000 quality approved block paving sealer 
  • Suitable for most patio slabs & block paving
  • Average coverage 3.5 sq metres per litre
  • Will not blister or peel, hardens & seals concrete permanently
  • Make sure before applying that the surface temperature is between 12 - 25°C
  • Tough, Durable and Hard Wearing
  • Ultra-violet light and weather resistant

Recommended coverage
First coat: 2.0sq. metres per litre
Second coat: 3.5sq metres per litre




Smartseal Block Paving sealer can be applied using a sprayer unit or roller, at a rate of 2.0m2 per litre (pavers) 1st coat & 3.5 m2 per litre 2nd coat. A two-coat spray application is required to fully cover the jointing sand. The sealer will be tack free within 2 hours at 20°C and foot traffic may be permitted after 4 hours. Vehicles should be kept off the sealed area for a minimum of 24 hours at 20°C. These times may be increased or reduced depending on the ambient temperature. During the curing cycle, protect from rain. Do not apply when the ground temperature is above 25°C or below 12°C. All equipment should be cleaned with Smartseal cleaner fluid after use.

Deicing salts should not be applied directly on Smartseal block paving or concrete sealers. Salt chemically reduces the temperature at which water freezes and will result in water ingress into the concrete. Subsequent freezing may result in the concrete ‘seal’ being broken by the expansion of water as it freezes and white ‘pitted’ areas may become visible.



New block paving or cobble stone paving should be swept clean, ensuring there is sufficient well-compacted sand in the joints. Existing paving should be pressure washed to remove all surface debris. If the area is contaminated with weeds & moss then it should be treated with Smartseal Fungicidal Wash. Oil and other stains should be removed using Smartseal Cleaner / Oil Remover. The treated area should then be left to dry and the joints re-sanded & compacted to the lower edge of the paver chamfers with clean kiln-dried sand. Moisture in the paver & sand will inhibit penetration of the sealer and produce whiteness.

Technical & Test Data

Smartseal Block Paving sealer has been tested by the TRL (Transport Research Laboratory) and certified that it meets the SRV (Skid Resistance Value) for all categories of paving for local authority pedestrian areas and when heavily trafficked is suitable for special applications where risks of skidding are high as laid down in the UK Highway Authorities Tender Specification. Copies available on request.

Specification Clause

“Newly laid block or flagstone paving shall be treated with Smartseal block paving sealer to protect and stabilise jointing sand and enhance surface colour and increase abrasion resistance. All materials should comply with ISO9002 for Quality Assurance. All work should be carried out in conjunction with the manufacturer’s current technical data sheet and instructions for use”.

Health & Safety

Flammable liquid. Do not smoke. Keep application area well ventilated. Wear respirator when applying. Store in a cool place. Flash point 40°C (Abel-Closed Cup). Refer to the Health & Safety Data Sheet for further information.
