Chemforce Stain Protector

Chemforce Stain Protector – Advanced Impregnating Sealer for Stone, Pavers & Polished Concrete

Chemforce Stain Protector™ delivers industry-leading protection for porous building materials by combining superior water and oil repellence with long-lasting durability. Suitable for both indoor and outdoor surfaces, this high-performance impregnating sealer is designed for:

• Natural stone
• Brick and terracotta
• Concrete paving and polished concrete

Ideal for floors, patios, kitchens, bathrooms, terraces, pool surrounds (use Fortifier Plus™ for salt-water pools), and high-traffic commercial areas.

Key Benefits of Stain Protector

• Deep-penetrating, permanent bonding technology for maximum stain resistance
• Protects against efflorescence, picture framing, salt spalling, freeze-thaw damage
• Maintains original surface colour, finish, and slip resistance when applied correctly
• Highly breathable – allows moisture vapour to escape while preventing water ingress
• Strong hydrophobic barrier reduces mould growth and surface degradation
• Exceptional UV, chemical, and heat resistance – withstands commercial cleaning
• Made in Australia at Chemforce’s Sunshine West, Victoria facility

Preparation Before Application

• Test first: Apply on a small, inconspicuous area and allow 24 hours to assess results.
• Surface must be clean, dry, and free from residues.
• Apply between 5–35°C (40–95°F).
• Do not dilute – Stain Protector™ is ready-to-use.

How to Apply Stain Protector

1. Leave to penetrate for at least 10 minutes.
2. Generously apply STAIN-PROTECTOR^™ using low pressure hand sprayer, brush or microfiber / wool applicator. Very porous surfaces should have a mirror like wet look for at least 3-5 seconds. Avoid contact with surrounding areas.
3. Before it dries on the surface, apply a second generous coat.
4. Total application rate (for both coats combine) is one litre per 4 to 20 sqm (one gallon per 160 to 800 sq. ft) depending on surface absorption.
5. After minimum 10 minutes but, before the second coat dries, thoroughly polish the surface with clean, white absorbent cotton or microfiber towels (or similar) to remove ALL product residue. If residue has begun to dry, moistening a cloth with Stain Protector™ to ease removal.
6. Use an organic solvent e.g. alcohol or mineral spirits to clean equipment.
7. Avoid moisture contact with the surface for six hours after application.

NOTE: Sealer will NOT prevent surface etching, scuff marks or mechanical wear and may lighten or darken some surfaces. Stain Protector repels water and oil, but not solvents, so solvent based materials, such as marking pen ink can still stain the treated surface, but will penetrate less, and be easier to remove. All spills should be cleaned up immediately to minimize absorption.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
