Natural Stone Sealer - ULTIMATE ENHANCER
FOR SANDSTONE ONLY! (Sample, 1L,5L,25L Sizes) - NOT recommended for use on Limestone, Granite or Slate. Average coverage of 4- 6 m²/litre, up to 5 years protection; for Sandstone only.
Our Ultimate Colour Enhancing Sealer will transform natural Sandstone** and Indian Sandstone** patios, drives and floors. To avoid trapping in moisture, the sealer is fully breathable and once applied it will leave the surface with that 'just rained on' look, bringing to life the natural rich colours within the stone or slate. The Ulimate Colour Enhancer is a 'colour intensifier' for natural stone surface where the preferred look is when the surface has been rained in and the colours are darkened.
By 'impregnating' into the surface and sealing from within, our Ultimate Colour Enhancing Sealer offers the very latest in protection.. Solvent Free and safe to use around animals, children and vegetation, the sealer is easy to use with application by roller, sprayer or paint brush.
**Exceptions to Sandstone suitability:
Please note this product is not suitable for Kandla Grey (mid and light grey) Sandstone and is NOT recommended for use on Limestone, Granite or Slate
If your Natural Stone has been recently 'pointed' using a 'sweep in' pointing compound, please contact us before application on 01268 722500
PREPARATION:Due to the effects of Efflorescence and Natural Salts and Minerals, that can permeate through Natural Stone, it is recommended not to seal for a minimum 4 months after installation.
If required, pre-treat the surface of the sandstone with an appropriate cleaning product, then fully clean the surface of the sandstone using a pressure washer and leave to dry thoroughly for at least 3 days. If pointed within the last 6 months using a 'sweep-in' jointing compound, the surface must be cleaned using Smartseal Residue Remover and left to fully dry prior to applying the sealer.
COVERAGE:
This is dependant on the porosity and texture of the Sandstone, but the average is 5-6mē per litre for the first coat and approx 10-15mē per litre for the second coat.
Prior to application always apply to a test area first in an inconspicuous area to determine suitability.
STORAGE & SHELF LIFE:
Store in a cool, well ventilated area. Keep container tightly closed.
Use within 12 months of purchase and within 3 months once open.
DIRECTIONS FOR APPLICATION:
Important: Once fully cured Smartseal Ultimate Enhancing Sealer is extremely difficult to remove, please follow application procedure correctly or call 01268 722500 for additional advice.
- Prior to applying, ensure the sandstone patio or floor is totally clean and has been dry for at least 3 days.
- Apply to a dry surface in temperatures above 15°C and no higher than 23°C. Application is recommended by sprayer, roller, microfibre mop, paint brush or on very dense surfaces by sponge.

- Apply second coat 'wet on wet' with same process of removing any sealer residue after approx. 45 minutes.
PLEASE NOTE: Depending on the surface enhancing effect after application, one coat to saturation may only be necessary to create the desired finish.

Q: Is Kandla Grey Sandstone a colour option or a make of sandstone?, ive just had a patio laid of Marshalls multi grey riven indian sandstone, and i want to seal it using your ultimate enhancer as the flags look amazing when there wet, but a bit dull when dry, but seen the comments saying to not use the ultimate and go with the dry finish, would i be ok using the ultimate enhancer Thanks
A: Kandla Grey sandstone is a make of sandstone but is often used to describe many types of light grey sandstone. We generally recommend using the dry finish natural stone sealer as sometimes colour enhancing sealers can react with this type of sandstone. We would suggest trying a sample of the product you want to apply first to ensure it meets your expectations, prior to applying over the entire area.
Q: Hi, I have just had a Riven Raj Green sandstone patio and path layed. Would like to ask a couple of questions about your Sandstone Natural Stone Sealer - ULTIMATE ENHANCER. When dry the colour of the slabs is very quite subtle but when they are wet the colour is very much enhanced. With this sealer I assume after it has been applied the subtle colour in the stabs will be enhanced? Although will the colour of the slabs enhance in the same why when they get wet after the sealer has been applied. Compared to when the slabs had no sealer applied and they were wet? I am thinking after the sealer has been applied and the stone has been waterproofed the previous natural colour enhancement when wet will be lost.
A: The ultimate enhancer will give a strong colour enhancing effect on sandstone. It will darken the stone but we would not classify this as a wet look sealer as it will not leave any type of sheen on the surface. It is more of a matt damp look. The best way to satisfy yourself regarding the look of the surface of the sandstone is to order a sample and carry out a test patch in an inconspicuous area first before applying to the entire area.
Q: Just had a sandstone patio put in. How long before I can use the ultimate enhancer?
A: You need to make sure all the salts and minerals that could 'migrate' through the natural stone from the sandstone itself and basework, showing as whiteness, efflorescence or blemishes are no longer present or have not formed Matt. We would suggest leaving 2-3 months and assessing from there. Hope that helps.
Been waiting for some weeks to get the requisite dry window. Applied the sealer and now the result is truly amazing. The sandstone is transformed from dull same colour to show the vibrant shades that the stones had when first laid. I recommend this wholeheartedly as I do the technical dept. response to my questions.
The natural stone sealer is a great product brings slabs up like new
Excellent product I used so far to seal my sandstone patio after installation.
