SLABSEAL® 35 is a water-based, high-solids acrylic grout coat and breathable concrete sealer engineered for professional resinous flooring and decorative concrete applications. SLABSEAL® 35 delivers fast dry times, UV stability, and dependable adhesion for vinyl chip systems, cementitious overlays, and decorative concrete surfaces.
This versatile acrylic coating is designed to support fast-return-to-service flooring installations while meeting VOC regulations across the United States and Canada.
Typical Applications
SLABSEAL® 35 is commonly used for:
- Vinyl chip grout coats in decorative color chip flooring systems
- Clear or pigmented sealing of concrete and cementitious overlays
- Decorative concrete surfaces requiring breathability and UV stability
- Commercial and light industrial flooring environments
When to Use SLABSEAL® 35
Use SLABSEAL® 35 when you need:
- A smooth-flowing grout coat for vinyl chip flooring systems
- A breathable acrylic sealer for decorative concrete or overlays
- A UV-stable finish for interior or exterior exposure
- A fast-drying coating that supports rapid recoat and return to service
- A VOC-compliant solution for regulated environments
SLABSEAL® 35 is well-suited for professional resinous flooring installations in commercial spaces, retail environments, automotive service areas, and light industrial facilities.
When Not to Use SLABSEAL® 35
Do not use SLABSEAL® 35 if:
- The concrete substrate contains unreacted silicates or densifiers
- Relative humidity exceeds 85% during application
- Substrate conditions cannot meet published preparation requirements
- Chemical resistance beyond acrylic performance is required
For substrates affected by silicates or densifiers, use SLABLOC® 50 prior to application.
Why 35% Solids Matters
SLABSEAL® 35 is formulated at 35–38% solids by volume, providing a balance of film build, adhesion, and breathability that standard low-solids acrylic sealers cannot achieve.
Higher solids content allows SLABSEAL® 35 to:
- Build a more uniform protective film per coat
- Improve adhesion to properly prepared concrete substrates
- Reduce lap lines and visual inconsistencies
- Enhance durability while maintaining vapor permeability
This formulation makes SLABSEAL® 35 especially effective as a vinyl chip grout coat and as a breathable sealer for decorative concrete and cementitious overlays.
