Product Reviews
By Rod Tyrrell-PriceFROM Epping

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.

Product Description

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.

The high quality unique non solvent formulation of this sealer for most** types of Sandstone means it will not only dramatically improve the look of the stone, but provide long term protection as well.

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

Technical

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 5-6m per litre for the first coat and approx 10-15m 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 15C and no higher than 23C. Application is recommended by sprayer, roller, microfibre mop, paint brush or on very dense surfaces by sponge.
  • Apply first coat evenly and generously. Allow to dry for about 45mins then remove any excess sealer residue with a dry roller, cloth or dry 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. 

Make sure no rain is forecast for a least 8 hours after application. Do not attempt to clean using a pressure washer for at least 7 days after application.
 
Protect surrounding areas with masking tape, when applying the product, wear gloves and googles at all times. ALWAYS APPLY TO TEST AREA FIRST.

**Please note: This product is NOT recommended for use on Limestone, Granite or Slate**

MAINTENANCE:
Avoid use of aggressive or abrasive cleaning products, failure to do so can reduce lifespan and effectiveness of the sealer.

Product FAQs

Q: Is this suitable for sawn mint sandstone?

Lauren Sherer

A: It is suitable but we would always suggest trying a sample first to ensure the product meets your expectations.

Response from Nick

Q: Hi. How much sealer would I need for 60metres of Kandla Grey Paving. I am looking at the Ultimate Enhancer Sealer. Many Thanks

Kim Burroughs

A: Due to the mineral composition of Kandla Grey Sandstone, when a sealer is applied that contains polymers that 'enhance' the colour or provides a wet look finish, the appearance of the sandstone can be patchy. This is why only the 'dry finish' sealer is recommended. Certainly this could be an issue if the ultimate enhancer is applied to Kandla Grey Paving.For 60m2 we would suggest 20L of sealer. Hope that helps.

Response from George

Q: Does the Ultimate Colour Enhancing Sealer provide protection against algae, lichen and staining? Which product is better for sealing Sawn Mint Indian Sandstone, the Natural Stone Sealer ULTIMATE ENHANCER or COLOUR ENHANCER? I like the look of my patio when it is wet after it rained.

Frank

A: The Ultimate Colour Enhancing sandstone sealer will make the sandstone much less porous, which helps to inhibit the growth of algae and lichen on the surface. Any spillages (oil, wine etc)will stay on the surface longer which will help you remove them easier. however, we suggest trying to remove any spillages from oil, wine etc ASAP as they will eventually work their way into the stone if left for a loger period. Either sandstone sealer can be used to seal the sandstone, it would be up to you to decide which finish you prefer. We would always suggest trying a sample first to test before making a purchase.
