Excellent product and easy to use

By Michael O Connell

Well explained by the smartseal team before purchase. I was using it inside a chalet style build I have. I was hoping for a darker finish, but that has nothing to do with the product. Did two coats of 25 square meters with one 5 litre can so have a full can left.

Consistency was very good and it went on easy. Would use this again.

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

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 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.

Concrete Sealer for External surfaces (solvent based)

Sealer for concrete drives, industrial floors and paths

Our sealer for external concrete is designed to protect concrete from all forms of deterioration. Smartseal concrete sealer should only be applied to concrete slabs that have been laid at least 7 days. A durable hard wearing sealer for driveways & other areas of hardstanding concrete. Also used as a garage floor sealer and concrete dustproofer.

Concrete Sealer Benefits

  • Provides Excellent protection and durability
  • Application by solvent resistant sprayer, roller or brush
  • Stain resistant
  • Manufactured to BS5750/ISO9000 standard
  • Reduces efflorescence
  • Does not peel or blister, hardens and seals all forms of concrete
  • Leaves 'damp' colour enhancing sheen on surface

Approximate Coverage
3 to 5m2 per litre per coat dependent on nature of concrete and method of application. For best results, apply 2 coats, if being used solely as a dustproofer, 1 coat is normally adequate. Clean tools with Smartseal Cleaning Fluid.

ENSURE SUITABLE SAFETY WEAR, MASK, GLOVES and GOGGLES are worn at all times during use of product.



Only apply to clean surfaces that are totally dry. Apply with a solvent resistant sprayer unit, paint brush or roller, Avoid over application and pooling. Two coats of concrete sealer are recommended, leave at least 2 hours between coats, can be re-applied at anytime.

Do not use deicing salts on areas concrete sealer has been applied. Salt chemically damages the surface, will reduce lifespan and damage the sealer allowing water ingress. 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.
