Designed for new and existing concrete, the range includes solutions for subfloors, car parks, warehouses, commercial facilities, civil structures and other concrete elements.
The right Oxtek product depends on the age and porosity of the concrete, the moisture risk, the intended floor finish and the exposure conditions. Compare the products below to identify whether your project requires a moisture suppressant, concrete cure, invisible penetrating sealer, stain-resistant treatment or reinforcement corrosion protection.
Oxtek Product Range Overview
X200 Densi-Proof – Moisture Control for New & Existing Concrete
Oxtek X200 Densi-Proof is a penetrating treatment designed to cure, densify, harden and permanently control moisture within suitable concrete. It is ideally applied at the time of pour but may also be used on existing concrete where the surface is clean and porous. It is commonly specified where concrete will receive floor coverings, coatings, adhesives or sealers.

Tip: Do not select an Oxtek product by finish alone. Start with the concrete condition and performance requirement, then confirm compatibility with any floor covering, adhesive, line marking paint, topical coating or subsequent sealer.
Why Choose Oxtek Concrete Treatments
- Penetrating technology: many Oxtek products work within the concrete rather than forming a conventional surface membrane.
- Moisture management: dedicated products are available for new slabs, existing concrete and surfaces receiving impervious floor finishes.
- Concrete performance: selected systems combine curing, hardening, densifying, waterproofing and resistance to dust or contamination.
- Application-specific options: the range includes products for car parks, warehouses, subfloors, reinforced concrete and decorative interior floors.
- Low-VOC water-based range: Oxtek describes its broader range as water based and low VOC, with product-specific technical information available.
- Technical support: project specifications, applicator training and project-specific warranties may be available for qualifying systems.
Oxtek Product Selection Checklist
1) Is the concrete new or existing?
Time-of-pour products can support curing while also delivering other protection. Existing slabs must generally be clean, sound and porous enough for the treatment to penetrate.
2) What problem needs to be solved?
Separate moisture suppression, curing, dust reduction, stain resistance, surface sealing and corrosion protection. A concrete cure such as X100 is not automatically a moisture barrier, while X200 and Moisture Fix are intended for moisture-control applications.
3) Will the slab receive flooring or a coating?
Confirm compatibility with vinyl, resilient flooring, adhesives, epoxy coatings, acrylic sealers, line marking and other finishes. Follow the relevant waiting period and preparation instructions before installing subsequent systems.
4) Is the surface porous or highly burnished?
Penetrating treatments require access to the concrete pore structure. Highly steel-trowelled or over-burnished surfaces may restrict penetration and can require a different product or preparation method.
5) What exposure will the concrete face?
Consider vehicle traffic, oil contamination, UV exposure, marine conditions, freeze-thaw cycles, food environments, internal decorative use and reinforcement corrosion risk.
6) Is a warranty or formal specification required?
Oxtek warranties are not automatic retail guarantees for every application. Project-specific warranties may require consultation, an approved specification, quality assurance and trained application.
Practical Tips for Better Results
- Confirm the concrete is clean, porous and free from curing membranes, laitance, contamination or coatings that may block penetration.
- Do not assume every Oxtek product is interchangeable; use the current technical data sheet for the exact product and substrate.
- Apply at the specified coverage rate and avoid leaving excess material on the surface.
- Test a representative area when appearance, burnishing, porosity or compatibility is uncertain.
- Use the recommended spray, broom or application method and protect adjacent glass, metal and finished surfaces from overspray.
- Check the required interval before applying flooring, adhesives, paint, line marking or other topical coatings.
- Seek technical guidance for marine, potable-water, food-processing, antimicrobial or structural concrete applications.
FAQs – Oxtek Concrete Protection
What are Oxtek products used for?
Oxtek products are used to cure, densify, harden, waterproof, seal and protect concrete. The correct product depends on whether the project involves new or existing concrete, subfloor moisture, surface contamination, vehicle traffic, reinforcement corrosion or a decorative finish.
What is the difference between Oxtek Densi-Proof and Moisture Fix?
X200 Densi-Proof is ideally applied at the time of pour and combines curing with permanent moisture control, although it can also be used on suitable existing concrete. X220 Moisture Fix is formulated as a practical moisture-suppression treatment for existing and new concrete and can be applied by broom or spray.
Can Oxtek be applied to old concrete?
Yes, selected Oxtek products can be applied to existing concrete when the substrate is clean and porous. Previous sealers, curing compounds, coatings, contamination or excessive burnishing can prevent proper penetration.
Will Oxtek waterproof concrete blocks?
Oxtek states that its waterproofing range is intended for concrete rather than concrete blocks. Some products may assist with efflorescence on suitable render or screed, but this should not be represented as a warranted block-waterproofing system.
Can flooring or paint be applied over Oxtek treatments?
Yes, depending on the product and system. Compatibility, preparation and waiting periods vary. Oxtek advises that topical finishes may generally be applied sooner on treated existing concrete than on concrete treated at the time of pour, so the current technical data sheet must be followed.
Are Oxtek products low VOC?
Oxtek describes its range as water based and low VOC. Individual VOC classifications and certifications should be checked against the latest product technical and test documentation.
Which Oxtek product is suitable for car parks or warehouses?
X550 Carpark Warehouse is the primary current option for hardening, dust reduction, tyre-mark reduction and resistance to oil contamination on suitable car park and warehouse concrete. Paintworld also lists X520 Warehouse; confirm its current technical status and availability before specifying it.
Does every Oxtek purchase include a 15-year warranty?
No. Oxtek states that warranties are project specific and can require consultation, an approved specification, application training and quality-assurance documentation. Confirm warranty eligibility before purchase or application.
