Sikagard-300 HD WB is a magnesium fluorosilicate concrete hardener and dustproofer that bonds chemically with concrete to strengthen and harden floors that are porous, readily absorptive, and only moderately hard. Engineered for demanding industrial environments where concrete floors face heavy traffic, abrasion, and chemical exposure, this proven formulation delivers exceptional durability and performance enhancement. With its unique chemical reaction mechanism, it penetrates deep into the concrete matrix to create a permanently hardened surface that resists wear and contamination.
This concrete treatment achieves remarkable results, reducing abrasion wear by up to 96% compared to untreated concrete surfaces while maintaining breathability and dimensional stability. Its non-film-forming chemistry eliminates the maintenance issues associated with topical coatings, instead creating an integral part of the concrete structure. Compatible with most resilient tile adhesives and USDA-compliant for food processing environments, Sikagard-300 HD WB provides long-term value through reduced maintenance costs and extended floor service life in critical commercial and industrial applications.

Key Features of Sikagard-300 HD WB
Exceptional Abrasion Resistance
Reduces concrete wear by 96% after 30 minutes of testing (ASTM C-779), transforming moderately hard surfaces into dense, durable floors.
100% Chemical Reactivity
Reacts completely with free lime in concrete to produce a dense, abrasion-resistant surface while maintaining natural breathability.
Superior Binding Action
Tightly binds cement, sand, and aggregate particles together for improved structural integrity and enhanced chemical resistance.
Non-Film Forming Technology
Becomes an integral part of the concrete structure rather than forming a surface coating, eliminating delamination and reducing maintenance requirements.
Broad Chemical Resistance
Provides resistance to over 60 industrial chemicals including acids, salts, oils, and organic compounds per ACI Standard 302.1R specifications.
Food-Safe Certification
USDA-compliant formulation approved for incidental contact in meat and poultry processing facilities.
Recommended Applications of Sikagard-300 HD WB
Sikagard-300 HD WB is specifically formulated for contractors and facility managers who need to transform weak or moderately hard concrete floors into high-performance surfaces capable of withstanding industrial demands. Its penetrating chemistry and chemical binding action make it particularly effective for upgrading existing floors without the complexity of overlay systems.
Ideal Applications Include:
- Manufacturing facilities with heavy machinery and equipment
- Warehouse floors subject to forklift traffic and material handling
- Food processing plants requiring chemical-resistant, cleanable surfaces
- Chemical processing facilities exposed to aggressive substances
- Retail and commercial spaces needing durable, low-maintenance floors
- Terrazzo surfaces (non-resinous types) requiring hardening and protection
- Exterior concrete areas exposed to weather and traffic
- Floors requiring improved resistance to oil, grease, and chemical spills

Frequently Asked Questions
What surfaces can Sikagard-300 HD WB be applied to?
It works on concrete and non-resinous terrazzo surfaces. The concrete must be properly cured (preferably 28 days old, minimum 10 days) and free from previous sealers or curing compounds unless mechanically removed.
How much will abrasion resistance improve?
Testing shows a 96% reduction in wear depth compared to untreated concrete. Treated surfaces show only 0.0025 inches of wear after 30 minutes versus 0.0264 inches for untreated concrete.
How many applications are typically required?
Most concrete floors require two applications with specific dilution ratios. Light to moderately troweled floors use 1:1 dilution for the first coat and 1:2 for the second. Dense or polished concrete may require three applications for optimal results.
What is the coverage rate?
Coverage varies by surface type from 100-300 ft²/gallon of mixed material. Light to moderately troweled floors typically achieve 100 ft²/gallon, while dense surfaces may reach 300 ft²/gallon.
Can it be used in food processing facilities?
Yes, Sikagard-300 HD WB is USDA-compliant for use in meat and poultry areas where incidental food contact may occur.
What chemicals will it resist?
It provides resistance to over 60 industrial chemicals including aluminum sulfate, lactic acid, mineral oils, sodium chloride, various organic acids, and many food processing chemicals as specified in ACI Standard 302.1R.
How long is the shelf life?
15 months when stored properly in unopened containers between 35-85°F (4-29°C). Keep from freezing and store in original packaging.
What application methods can be used?
Apply by roller, spray, brush, or squeegee. Bubbling during application indicates proper chemical reaction with the concrete. Always distribute evenly and remove excess puddles for uniform results.
