Duram S900 Clear Penetrating Sealer

Self Priming. No primers needed.

Product Description

Duram S900 is a clear, high pH, deep penetrating siloxane waterproofing solution. Duram S900 penetrates in to the tissue of porous substrates and creates a waterproofing barrier below the surface preventing the ingress of water. Duram S900 is an effective waterproofing solution and stops leaks without lifting tiles or changing the overall appearance of the surface. Duram S900 also solves the problems associated with water penetration such as corrosion of steel reinforcement, friability and binder loss of surfaces, fungal and bacteria attack and degradation due to carbon dioxide permeability. Duram S900 is capable of withstanding high pH conditions such as found in new concrete and lime based mortars and bricks. Duram S900 still allows the diffusion of vapours or ‘breathing’ ability of the substrate.

Product Uses

The properties of Duram S900 make it ideal for the following uses:

• Waterproofing external concrete, cement, cement render, face brick, block walls, sandstone, porous pavers and other porous surfaces.
• Prevention or minimization of Efflorescence and Lataince (white salt spotting or leaching).
• Protection of sandstone.
• General rain water barrier.
• Assists in preventing Mould and Fungus growth.
• Anti-graffiti protection (sacrificial coating).

CAUTION: Sealed surfaces may be slippery when wet.

Suitable Surfaces

Duram S900 has been used successfully on the following porous substrates when used correctly:

• Concrete,
• Cement,
• Cement render,
• Block work,
• Face bricks,
• Porous pavers,
• Grout (tiled areas),
• Sand and cement tile beds,
• Sandstone,
• Terracotta pavers and other porous surfaces.

• Duram S900 penetrates into the tissue of the substrates and accordingly relies its soundness and stability.
• Duram S900 will not bridge or seal cracks.
• For Duram S900 to work effectively, sufficient product must be absorbed into the surface to fill the voids within the substrate. Highly porous, sandy and friable surface may not contain sufficient density to allow the Duram S900 to create an adequate ‘build-up’ of S900 to form waterproofing barrier. Test area are highly recommended.
• The quantity of S900 needed for a given area is subject to its density, porosity, thickness, soundness and condition which may not be apparent.
  As an Anti-Graffiti Coating
• The surface must be very well saturated so that a layer of the cured coating lays across the surface. Inadequate saturation and coverage will negate or diminish the effectiveness of the product as an anti-graffiti coating.
