ProSeal 898 Gloss Concrete Sealer

Pro Seal 898 is low VOC making it the sealer of choice for all indoor sealing applications!

A penetrating nano-sealer with super tight cross-linking that keeps out even the finest stains!

Apply to wet surfaces for quicker turn-around and better results!

ProSeal 898 is the latest evolution of the Water Based Sealers Pro Seal range. It is specifically designed to penetrate deep into dense surfaces like polished concrete and dense natural stones like marble and honed granite. This was accomplished by re-engineering the Nano base polymer to a size 10 times smaller than ProSeal 896. The much tighter cross-linking also results in reduced water vapour permeation rates, higher gloss and higher durability and outstanding stain resistance.

These properties make it a high performance, environmentally friendly sealer for all types of concrete and stone. Suitable for warehouse floors, burnished concrete floors, dense natural stone, benchtops and furniture, natural stone tiles and cladding; and venetian plaster.

Why is penetration so important? When applied correctly Pro Seal products penetrate below the surface to form a permanent matrix within the pores of the substance being sealed. This matrix will remain in place for the service life of the surface. It not only keeps out stains, but also serves to strengthen the surface of the materials being sealed. Since it becomes one with the surface it is impossible for the sealer to peel, blister or fail. Additional coats will build on top of the matrix and form a film above the surface to provide enhanced gloss and a wear layer to protect the surface from chemical and mechanical damage. Applying additional coats every few years will rebuild the wear layer and provide the best possible level of protection.

Like all products in the Water Based Sealers range ProSeal 898 is applied to damp surfaces. This ensures the best possible protection as surfaces can be sealed immediately after cleaning. It’s also a time saver in many cement based manufacturing & construction process as the sealer can be applied and will fully cure within the normal curing and drying time. Floors can be sealed as soon as trowelling is finished, tiles can be sealed as soon as the grouting is done, and concrete furniture can be sealed straight out of the mould. Further, the MRT will ensure better curing and strength development too.

With extremely low VOC’s it’s a safe and responsible choice for all indoor surfaces, but it has the durability and UV stability to be used outdoors, in any environment.

ProSeal 898 is used as a standalone sealer for dense surfaces or as the final coat in a sealing system for any other surfaces. Being fully compatible with the Water Based Sealers range it will seamlessly adhere to and enhance surfaces pre-treated with ProSeal 770 and/or ProSeal 896.
