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. https://youtu.be/ml3zzAKkzbY

Questions & Answers


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.
