Want to protect the appearance of your beautiful stone and make maintaining it easier?
Sealing natural stone can prolong its life and maintain its characteristics. Kebur can help you by pre-sealing for you, so when your paving arrives, it is ready to install in any weather.
We supply and deliver your stone ready-sealed with Dry-Treat Stain Proof or Intensifia, deep penetrating sealants which inhibit moss and mould growth, and provides protection from stains, efflorescence, salt, freeze-thaw spalling and picture-framing. Stain-Proof provides deep-penetrating long-lasting premium protection, whilst Intensifia provides protection alongside colour-enhancement.
Prices start from £11.95 per m2 including VAT. This includes a performance warranty and free stone cleaner worth over £25 (when you order 15m2 or more). Ask us for details.
Frequently asked questions
Is pre-sealing recommended for all types of natural stone?
All natural stone has variation in porosity and has a chance of staining from oils, grease, dirt and its natural surroundings. Some types of natural stone are more prone to staining and weathering than others. We highly recommend pre-sealing the following natural stone:
Sealing these stones will give them the best possible protection against moss and mould growth, weathering, traffic wear, efflorescence, picture framing, salt attack and freeze-thaw attack. Pre-sealing can prevent problems with installing these stones such as jointing compound and mortar stains.
Using a sealant or colour-enhancer can protect against stains and enhance the colour for Asian Blue Limestone and Natural Sandstone. Whilst not necessary to protect the stone itself, using a colour-enhancer will slow the fading process and/or enhance the appearance of Blue-Black Limestone and Andhra Grey Limestone.
Why use Kebur’s pre-seal service?
Pre-sealing means that your stone arrives on site sealed and ready to install. Our service gives reliable and even coverage of each stone, to ensure the best protection, and the Dry-Treat Stain-Proof’s performance warranty (15 years for Stain-Proof and 5 years for Intensifia).
Can’t I just do it myself?
You can pre-seal your stone yourself, and we offer Stain-Proof that you can use at home. The disadvantages of doing this are that you are dependent on dry weather and the stone needs to be completely dry before installation. This can hold up progress on landscaping projects and means that the best time to install is after a warm dry spell in the spring or summer.
Are there cheaper products than Dry-Treat TM?
Kebur has chosen to use Dry-Treat products for its pre-sealing service because its sealers are different in two important ways. Firstly, they penetrate deeply into the stone. Secondly, they make a permanent chemical bond with particles inside the capillary pores below the surface, while allowing moisture to evaporate. Our service also gives you a performance warranty.
How long will it take to seal my stone?
We are advising that you should allow around 2 weeks for your stone to be sealed, though in many cases we may be able to do it quicker than this. Please ask your sales advisor when you order.
Do I need to pre-seal porcelain?
No, because Kebur’s porcelain has a very low water absorption rate (less than 0.05%) it does not require sealing.
I have sealed my stone but after a while there are marks on the surface
Sealing a surface with a Dry-Treat Stain Proof impregnating sealer will make the surface water and stain-resistant, but not dirt resistant. The sealed surface should be cleaned as regularly as a non-sealed surface. If a problematic substance such as sticky tree gum falls on the surface, it will still be difficult to clean off, but should not permanently stain the surface.
Sealed stone can still scratch and darker coloured stone will show up scratch and scuff marks more than lighter ones.
Will my stone look different?
Your stone will tend to look slightly darker when sealed and it will not then darken when wet. Intensifia can also bring out the natural colour variation in the stone and show details like veining more clearly.
What cleaner should I use on my sealed stone?
What does the warranty cover?
If an area of porous building materials is prepared and sealed by a Dry-Treat Accredited Applicator who holds a current license you will qualify for a written warranty. The warranty is between Dry-Treat and the property owner, and states that if the sealed surface is properly maintained but fails then it will be re-sealed free of charge. A failure is a treated surface that does not repel water and/or stains from a non-acidic non-solvent based liquid when compared to an untreated surface.
How should my sealed stone be laid?
Once we deliver your pre-sealed natural stone the items will be ready to install. The sealing does not change the way the paving should be laid.
If using a landscaper, let them know you have pre-sealed the stone so they don’t try and seal again after the installation.
You may want to buy a small amount of extra sealant so you or your landscaper can apply it over the top of the joints or exposed cuts after installation.
