Description
DENSACRETE PREMIUM is an oil and water resistant concrete densification sealer based on metal silicates. DENSACRETE PREMIUM is a non-film-forming penetrating sealer that can penetrate, block concrete capillaries and react with the concrete to form a hard, dust-proof and colour-enhanced concrete finish. Apart from concrete densification sealing, DENSACRETE PREMIUM imparts oil and water resistance to the concrete, effectively making it a water and oil-proof concrete finish. Furthermore, a smooth or gloss finish can be achieved by concrete polishing. DENSACRETE PREMIUM will not leave visible residues or efflorescence after the treatment.
Recommended Uses
DENSACRETE PREMIUM is used as an oil and water resistant concrete densification sealer for treating concrete, including residential driveways or garage floors, commercial car parks, and factory or warehouse flooring. Applications include treating new and old concrete slabs for strengthening, dust-proofing, and creating oil and water resistance. DENSACRETE PREMIUM provides good resistance against water and oil absorption and reduces oil staining. The sealer may also treat other masonry substrates, including sealing natural stone, clay bricks and ceramic tiles. However, a test should be conducted before application to determine the product's suitability for the purpose
The key features of DENSACRETE PREMIUM include:
- Resists water and oil penetration and reduces oil staining
- Penetrates and reacts with concrete to ensure durable protection
- Leaves no visible residues or efflorescence after treatment
- Enhances concrete colour without changing the surface characteristics
- Ready to use or dilute with water before use
- Environmentally friendly water-based technology with nil VOC
Use Instructions
Surface Preparation
Before application, the concrete surface should be completely cleaned of any surface contaminants that may impede the penetration of DENSACRETE PREMIUM. The surface should be allowed to dry before application.
New concrete should be properly cured. Curing compounds, release agents, and coatings/membranes should be completely removed, cleaned from the surface, and allowed to dry before applying DENSACRETE PREMIUM. In the case of acid-treated concrete, the concrete should be completely neutralised, rinsed with water, and allowed to dry before the application.
For polished concrete, the surface is firstly removed by grinding up to 200 grit or any desired finish to expose the capillaries or aggregates before applying DENSACRETE PREMIUM. This will ensure maximum sealer absorption to achieve optimum concrete densification and oil and water resistance by applying DENSACRETE PREMIUM.
Application
DENSACRETE PREMIUM should be mixed well before use. The sealer may be applied with a low-pressure hand sprayer, brush or broom. The product should be evenly flooded onto the surface. Pooling should be avoided. To achieve maximum absorption, ensure the sealer is present on the surface as a mirror-like wet film for up to 30 minutes. If the first coat is quickly absorbed by the surface, the second coat is applied immediately while the surface is still wet (wet-on-wet method). For porous and permeable concrete, this wet-on-wet application may be repeated until the surface is saturated, with no further absorption of the sealer being achieved. Remove excess sealer from the surface if it hasn’t been absorbed by the surface within 30 minutes. Any excess sealer on the surface may dry to unwanted residues that may become difficult to remove after the product is cured.
It may help to achieve better penetration by pre-diluting the sealer at 1:1 with clean water before use. However, this may mean more wet-on-wet applications are required to achieve the desired result.
A final application is required after the previous application has been cured for 24 hours. It is recommended that no further polishing is undertaken after the final application. Polishing or buffering at this stage may reduce the oil and water-resistant effect imparted by DENSACRETE PREMIUM. Further application of DENSACRETE PREMIUM may be applied if advanced oil and water resistance is required for the treated concrete.
If an alternative desired polished concrete finish is required, then other TECH-DRY oil and water-repellent sealers may be applied as a finish sealer after the final polish.
Consumption Rate
The application rate of DENSACRETE PREMIUM varies depending on the porosity of the concrete. Dense or new concrete will have a low absorption rate, whereas porous and permeable or old concrete will absorb more sealer. The consumption rate varies from 5 – 20/m2 per litre per coat or could be out of this range significantly.
After Application and curing
Curing starts immediately after application. But it may take 24 hours or more to achieve better curing. Avoid heavy traffic for up to 24 hours. Optimum densification and oil and water resistance are expected after seven days of curing or more.
