Densifier

Description

This concrete sealer is a high-tech, clear, water-based sealer. The penetrating, inorganic, modified potassium silicate material “fuses” to concrete and appreciably reduces damage to concrete. The unique formula in Permacolour KS500 reacts with the calcium hydroxide in the concrete to form a calcium silicate hydrate gel. This gel is insoluble in water and hardens to densify the concrete, decreasing the moisture permeability and porosity. With the fusion, the substrate actually becomes more resistant to acid and other chemicals. Use in conjunction with Permacolour Repel SS to create the ultimate protection.

INSPECTION

 

This concrete sealer is a high-tech, clear, water-based sealer. The penetrating, inorganic, modified potassium silicate material “fuses” to concrete and appreciably reduces damage to concrete. The unique formula in Permacolour KS500 reacts with the calcium hydroxide in the concrete to form a  calcium silicate hydrate gel. This gel is insoluble in water and hardens to densify the concrete, decreasing the moisture permeability and porosity. With the fusion, the substrate actually becomes more resistant to acid and other chemicals. Use in conjunction with Permacolour Repel SS to create the ultimate protection. Surface must be structurally sound, dry, and free of oil, grease, curing agents, dirt, dust or other foreign matter. This product is designed for use over untreated concrete surfaces free from wax, dusting preventive sealers, deep penetrating sealers, bond breaking compounds and release agents and other similar chemicals that will interfere with proper penetration and lead to premature coating failures.

 

 

 

SURFACE PREPARATION

Before any existing concrete is treated, the area must be thoroughly cleaned. The surface should first be swept with a broom to remove any loose dirt. Then it should be cleaned by scrubbing brush/ broom, using Permacolour Concrete Cleaner. The abrasive action removes the film of consolidated dirt and exposes the true wearing surface. The concrete surface should be allowed to dry thoroughly for a minimum of 2 hours at 24°ᶜ once surface water has disappeared.

DO NOT apply over mildew. Mildew is a fungus, brown, black, grey or even white in colour, and will rapidly grow through any coating applied over it.

DO NOT THIN.

DO NOT apply to surfaces when ambient or surface temperatures are below 5C.

DO NOT allow the product to lay in puddles after application. Otherwise, excess dry product will be difficult to remove.

DO NOT apply externally if rain, frost or freezing temperatures are likely within 12 hours of application.

 

The surface may be slightly dampened just prior to application. Surface/ outside temperature should be 5 °C or more. Apply first coat by low-pressure spray - a common garden sprayer works well, or broom on. Apply an even blanket mist just to wet - not soak. Repeat with next coat when dry. On hard trowelled floors, an application using a scrubbing machine for several minutes will give an even penetration. Hand broomed in and scrubbed in will also do a satisfactory application. When over applied, white, chalky deposits may appear after drying. These can be stiff-broomed or power washed off.

On Freshly Poured Concrete Use as the cure and the sealer. Ideally, the best time to apply is when the concrete is completely finished and will withstand the weight of a man. Can be applied anytime after placement. Avoid rain or freezing for 12 hours. Apply by spray with medium saturation taking care, not to over apply.

*We recommend a maintenance mist after the 28 -45-day curing cycle complete, if possible, for best results.

On Old Concrete Use as a Penetrating Sealer. Always clean the surface, rinse thoroughly (especially when using oil/citrus-based cleaners). Let the surface dry and apply the KS500 by low-pressure spray or broom. Acid etching prior to KS500 application may be necessary for tight or smooth trowelled surfaces to aid in penetration. New Concrete Apply the KS500 by low-pressure spray to a clean surface. Acid etching prior to KS500 application may be necessary for tight or smooth trowelled surfaces to aid in penetration. Always test first for penetration receptibility prior to application.

DO NOT THIN OR DILUTE!!!

3 - 5 hours per application. Permacolour KS500 can be trafficked on immediately by light and heavy traffic of any type.

COVERAGE

Approximately 5-10m² / Litre/ coat.

MAINTENANCE

Surfaces coated with KS500 can be cleaned with a neutral pH cleaner such as Permacolour’s Concrete cleaner. The surface can also be coated with Permacolour’s Repell SS for the ultimate protection. For overcoating with other Permacolour sealers, please contact us for more information.
