Really strong smelling product - wear PPE even outside. It dries looking like it is still wet so really important to brush out any hollows otherwise it looks like puddles. It seals really well and the water runs off but it does look like it is permanently wet.

By K K

When first applied the sealer turned my concrete a very dirty looking dark grey (from light grey). This did lighten but has left the surface looking dirty, so this was disappointing. The block paviours that edge the drive look great with the sealant on. I now get tiny pools on the driveway after rain, so I know it is sealed.

By Martin Doughty From Worthing

The reason for the recent order is that I have bought and used the same concrete sealer before. It is easy to apply and the finish always restores the drive to its original finish. The perfect solution.

By Henry Ryan

Great product that does what it says on the tin. First coat was absorbed by the concrete but after the second and third coat of sealer it dried with a very slight beige tinge. No more dust when sweeping the patio! The water now runs off the patio towards the drain rather than being absorbed by the concrete.

By Ryan Heritage

The sealer went on really easily with a roller and covered quite a bit more than indicated, but maybe that's to do with the porosity of the concrete. As it rolled out it looked terribly uneven on the colour which worried me, but then as it dried all was well.

By Mike Kanter From Halstock, Dorset

The concrete sealer did exactly what it said on the tin. Was worried that the 5L wouldnt allow me to do two coats but as the first coat did its job, the 2nd coat glided on and I didnt need to use as much.

By Patrice Mulligan

Fair price, prompt delivery and sealed a large concrete patio just as claimed . Would recommend and use again.

By Jerry Dark

Excellent product. It sealed my dusty concrete perfectly. I shall use it on our Indian sandstone paving once it has been relayed properly!

By Jeffery Holdsworth From East Yorkshire

Excellent company really helpful about which product you need and brilliant videos showing how to prepare and use. We have recently recoloured and resealed our very sad looking imprinted concrete drive and now it looks better than new. Has drawn many positive comments from neighbors and passers bye. Also recoloured and resealed our large concrete paved patio which now looks great. Extremely fast delivery and after sale service. Have recommended this company to several people. Excellent.

By Susan Llewellyn

This stuff is BRILLIANT! I have a very old house which is a converted mill, so a mixture of very old stone and victorian concrete. We've had huge problems with moisture ingress through the concrete where its cracked and become porus over the years of being battered in this exposed Yorkshire hillside. This stuff goes on like a dream, dries really fast and has worked really well. Cant recommend enough - just make sure you follow the instructions and its warmish and dry when you apply it. Also scrubbing the surface with a wire brush really helps it penetrate really well.

By Joe Brook From Halifax

Used product to seal outdoor water feature for our PreSchool. Has sealed the concrete very well after it started to crumble away a little.

By John Freeman From Thurrock Christian Fellowship

good product, seals well.

By David Collins

Excellent product, does exactly what it claims

By Hugh Orde

Excellent concrete sealer, very pleased with results. I used slightly less than 25 litres to put 3 good coats on an 84m2 power floated concrete floor using a roller. Penetration was very good and the finished surface has a satin look that is not at all slippery. Would use again.

By Nigel P From Aberdeenshire

Ordered 2 x 5l tins to cover my garage floor. Was a little wary as to whether I would have enough but followed the advice from Smartseal and guess what? They were right! Have had to do it in 2 halves because of all the stuff in there. Just finishing off the 2nd half today. My floor was incredibly dusty. Not sure it was put down correctly in the first place. I swept up and then hoovered to get as much dust up as possible. I'm sure this will help it to be most effective. Seems to be a superb product. Time will tell. Would recommend using a face mask.

By Andrew Watson

interesting comment slippy when wet- highly probably it is used only two 5 litres when it said three was required - lower porosity on my surface.. very fine sand surface.. went on easily it will be 10 months before one will tell how good it is through the winter..

By J A Allen

Really good for the job on a hard stand with heavy use. Can't recommend enough.

By Ken Morgan

By Melody Manning

Hello Just a brief comment. Unlike a lot of similarly advertised products, yours totally delivers so thank you.

By Michael Rubbert From Southend

In September 2017, I ordered 2 x 5lt cans of concrete sealer, and found this more than enough to cover a garage floor area of 11 ft x 22 ft. Easy to apply with the 12" roller, but I take issue with the handle. I had to pair this down to fit the supplied roller frame. Why was this not done by you when I ordered all the bits to do the job? Anyway, it's done now, & after monitoring for a period, how very pleased I am with the results. I was assured it will last 10 yrs before requiring a furthur coating. Thanks again for your advice on quantities.

By John Offord From Hull

Very slippy when wet. Will be interesting to see how it stands up to severe frost during winter.

By Hugh Gallacher

Useful to have a sample to try first. Easy to apply and so far is working well so have ordered more.

By Elizabeth Boyle

The service from SmartSeal was excellent, they even phoned to check if we had the right sealant for the job and delivery was prompt. would have no problem recommending them if we ever needed to use it again. the concrete sealant was extremely 'smelly' so the mask we ordered was a must buy and we had to ventilate the area as well but it did a perfect job.

By Grahame Atkins

The product was easy to use the couler mixed well,the brush made it easy to put on,the cleaning fluid has doe its job.


The guys at Smartseal took time to explain the different products and sent me a sample to try on my concrete countertop. Very happy with the result and it was easy to apply. Swift delivery, good service, good product - thanks!

By Ian From Devon

Was expecting slightly more coverage per sq metre, but the concrete is quite porous. Clean up of equipment is a nighmare if you dont have the proper stuff. Has a pleasant odour, I followed the safety advice and purchased a mask and goggles. Will be buying another load, when the weather is nicer, as still have the rest of the drivway to seal.

By Jazz From West London

Fantastic product. Very tired concrete drive looks brand new again. Good company to deal with. Excellent value for the product.

By Graham Armstrong From Carlisle

My driveway has been down for 18 years was badly neglected. After calling Smartseal and discussing the details and sending photos I received a full itemised quotation of everything I would need. The order arrived the day after being placed and the finished result is amazing, it looks better that I could have hoped for. Thank you Smartseal and especially Nigel who gave excellent step by instructions even over a weekend. Great product and customer service.

By N.Austen From Middlesbrough

I have had new garage and car port installed, but the concrete base wasn't sealed. I had been looking at many products that seems expensive for the area that I needed to cover, and then I found Smartseal. Ordered and delivered quickly, and went on easily with a roller. Only had it down a few days but it looks like it's going to last. Great product. Thanks

By Andy From Cotswolds

By Clare Milne From Bristol

Nigel was more than happy to spend time with me to discuss how to renovate our concrete patio set which is tired and grey, and his knowledge and assistance was much appreciated

By Steve Laird From Stafford

Excellent support team/company; before they took my money Nigel phoned me to establish my requirements; He asked I email a photo; informed me of the correct products needed according to the wear & tear my picture highlighted; (I had ordered all the wrong things); the amazing part of this service was he made himself available on a Sunday to go through the process step by step with my husband. I was so impressed by the service that I have full confidence in recommending this to my friends as I know they will not be let down or dissapointed. PS; Everyone passes comment on my lovely shiney driveway,

By Mrs Lynes From Liverpool

By Neil Barrett From Lowestoft

rapid delivery!! Easy to use product, that gave excellent results.Very impressed .Thank you

By Chris Spruce From Southport

Great product, works a treat

By Mark Bailey From Seabridge, Newcastle Under Lyme

I found your website on Google while looking for a solution to the problems I was having with sealer peeling off my concrete imprinted driveway. I spoke to Nigel who asked me to send photographs of the drive whch I did. He quickly identified the problem, which it turned out, was caused by too much release being applied by the original installer, and the sealant was not adhering to the concrete as a result. He talked me through the problem and the solution step by step, and supplied the products to remedy the situation. He couldn't have been more helpful. I am a clerk not a concrete installer, but I followed each step carefully and hopefully turned the problem around. I also saved money by doing the work myself. A word of advice for anyone considering a patterned concrete driveway - the work was done by a friend of a friend, so always have the work done professionally by a recommended installer. Many thanks Nigel, photos to follow.

Solvent Based Concrete Sealer for External use

Concrete sealer for use on driveways, patios and floors

Smartseal sealer for concrete has been developed to give concrete long term protection. Our concrete sealer is suitable external concrete floors and other concrete based surfaces. For most types of surface two coats of concrete sealant are recommended for optimum results.

Concrete Sealer Benefits

  • Gives concrete superb long term protection
  • Easy to apply concrete sealer by sprayer or roller
  • Resists oil and stain penetration
  • Average coverage: 4 to 6m per litre per coat
  • Please ensure temperature is between 10 and 23C before applying
  • BS5750/ISO9000 quality approved concrete sealer
  • Reduces efflorescence from concrete
  • Will not blister or peel, hardens & seals concrete permanently
  • Enhances the surface finish of the concrete
  • Tough, Durable and Hard Wearing
  • Oil & Grease resistant



Brush or power wash concrete to remove any dirt or debris, only apply when surface is totally dry. Smartseal Concrete Sealer is best applied with a sprayer unit or roller, keeping sprayer head moving to avoid pooling. The first application must be applied to the surface and allowed to dry past tacky prior to applying the second coat. Avoid application in strong, direct sunlight - do not apply if rain is likely within 3 hours of application.

Deicing salts should not be applied directly onto any concrete sealer. 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.

Technical & Test Data

Smartseal Imprinted 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.

Health & Safety

Flammable liquid. Do not smoke. Keep application area well ventilated. Wear respirator when applying. Store in a cool place. Flash point 42°C (Abel-Closed Cup). Refer to the Health & Safety Data Sheet for further information.
