Pro-Seal 898 Natural Stone Sealer is a non-toxic, eco-friendly sealer. It is breathable and gets deeply into porous surfaces such as granite, marble and other natural stone products. Pro-Seal 898 is perfect for commercial use, workshops, and factory floors. It is an Australian product and is produced as a pure, fast working acrylic sealer.

Pro-Seal 898 has very small polymer chains. In this product the polymer chains are just a few nano-metres in length. This means that they can penetrate deeply into the material and connect to form an interlocking substance. The substance that is created strengthens and protects the sealed materials. The top of this substance sits above your material and provides a protective layer. You need to apply an extra coat every 3-5 years to top up the protective layer and safeguard your materials.

The majority of acrylic sealers have large individual polymer chains that form a thick film on your material’s surface. These films are not highly adhesive which makes them much more likely to delaminate (that is split apart into layers) and to fail than our penetrating sealers.

As Pro-Seal 898 Natural Stone Sealer has the smallest polymer size of our sealants, and is perfect for dense materials like granite, densified concrete, and marble. For more porous surfaces such as concrete, Pro-Seal 896 is more appropriate.

Pro-Seal 898 is a true nano sealer and provides a very thin, yet durable surface layer. It does not usually give you a high gloss result – however, if your surface is smooth the application of Pro-Seal 898 will result in a high shine. The surface can then be buffed to achieve an even greater gloss level.

Apply the product as a two coat stand alone sealing system on polished concrete or natural stone. You can also use Pro-Seal 898 as a final coat over Pro-Seal 896 or Pro-Seal 770 on more porous surfaces.

Pro-Seal 898 is used with confidence to seal and provide stain protection for all types of natural stone, including benchtops and tables.

It is also used as a final gloss coat together with another WBS product. We recommend Pro Polish 770 or Pro-Seal 896 for best results.

Pro-Seal 898:

  • Is a quality penetrating sealer
  • Provides excellent stain-protection for your products
  • Is excellent for use to seal natural stone benchtops and use on outdoor kitchens. It is UV stable, safe and completely non-toxic. It will not peel, or discolour with time
  • Is an excellent top coat option for driveways, alfresco areas, around the pool or wherever a higher gloss finish is required


Pro Seal 898 comes in a highly concentrated form that requires dilution with water prior to application. Completely saturate all substrates prior to application to ensure the best possible penetration and performance.

Suggested dilution rate: 1:3 (1 part product 3 parts water)

Dense Natural Stone and Polished Concrete:
Apply Pro Seal 898 as a fine mist spray and massage in thoroughly with a micro-fibre cloth. Ensure any access sealer is wiped off the surface. Failure to do so may result in an uneven finish.

Exposed Aggregate & Other Porous Surfaces:
Apply Pro Seal 898 only as a final coat in the WBS sealing system where a higher gloss level is desired. As a minimum, this involves pre sealing with Pro Seal 896.

Use a soft bristle broom to sweep out any pools that develop. The sealer can be walked over without concern during the curing process.

Doesn’t need to be stripped off prior to reapplication. While Pro-Seal 898 will remain in the substrate and provide protection for 15+ years it is recommended that a recoat be applied to the surface once every 3 years to maintain best appearance. This is particularly relevant for high use areas.
