HOW TO USE A WATER-BASED POLYURETHANE (PU) SEALEr
A PU sealer, short for polyurethane sealer, is a protective coating used to seal and protect surfaces like concrete, screeds, wood, and existing floor coatings. It forms a durable, clear film that enhances the appearance of the surface while protecting it from wear, stains, moisture, and chemicals.
Polished interiors
Offers the perfect balance between durability and aesthetics, giving floors a smooth,
cleanable finish in matt, satin, or gloss.
What it does
This type of sealer acts as a protective shield over a surface. Once applied, it hardens to create a tough, flexible layer that resists:
- Abrasion and scratching
- Chemical spills and stains
- Moisture and UV damage
- General wear from foot or vehicle traffic
2 Types of PU sealers
Water-based PU sealers: low odour, eco-friendly, quick-drying, and non-yellowing. Ideal for both interior and exterior use.
Solvent-based PU sealers: very tough and chemical-resistant, but have stronger fumes and longer drying times.
4 Reasons to choose a water-based PU sealer
- Eco-friendly and low odour
With fewer Volatile Organic Compounds (VOCs), and minimal fumes, water-based polyurethane sealers are safer for you and the environment. They’re perfect for both residential and commercial interiors where air quality matters.
- Fast drying, easy application
Projects move faster with a quick-drying formula that allows multiple coats in a single day. It is beneficial to choose a product with a smooth, self-levelling consistency to ensure an even finish.
- Durable and UV resistant
A quality sealer will stand up to heavy traffic, abrasion, and sunlight — maintaining its clarity and performance even in bright, exposed areas.
- Crystal-clear finish
Unlike solvent-based alternatives that can yellow over time, a water-based PU sealer enhances the natural beauty of your floors with a long-lasting, non-yellowing finish.
PU sealers are commonly applied to:
- Concrete floors (industrial, commercial, and residential)
- Cement screeds and self-levelling compounds
- Wood floors, epoxy or polyurethane flooring systems
Well-suited to light-coloured surfaces like concrete, wood or stone
