Smith's Paint Base Boost Application Instructions
Professional Decorative Concrete Application Guide
Smith’s Paint Base Boost is designed to enhance decorative concrete stain applications while improving color richness, bonding performance, and overall installation consistency for concrete floor and wall projects.
This guide helps contractors, decorative concrete installers, and DIY users properly prepare, mix, and apply Smith’s stain systems for long-lasting performance and professional finished results.
Important Application Information
If the application surface contains previous coatings, sealers, paints, or silicate treatments, Smith’s Base Boost should not be used. Base Boost is also not recommended for micro-toppings or overlay systems.
Always protect surrounding areas before application including:
- Walls
- Doors and frames
- Windows
- Cabinets
- Trim surfaces
- Adjacent flooring materials
Concrete Surface Preparation
Proper surface preparation is one of the most important parts of any decorative concrete staining project. A properly prepared substrate helps improve stain penetration, adhesion, durability, and final appearance.
The concrete surface must be free from:
- Grease and oil
- Dust and dirt
- Glue and adhesives
- Paint and coatings
- Surface contaminants
- Loose debris
Do not use muriatic acid etching as a cleaning method before applying decorative concrete stains.
Exterior Concrete Preparation
Broom-finished concrete may contain unstable high spots that can wear unevenly over time. Removing loose material before staining helps improve long-term durability and stain performance.
Recommended preparation steps include:
- Remove unstable surface material and debris
- Clean the substrate thoroughly
- Remove adhesives and contaminants
- Allow the surface to dry completely
- Perform a tape test before application
Pressure washing may be used where appropriate to help remove contaminants and preparation residue.
Interior Concrete Preparation
Interior surfaces should be cleaned using floor buffers, auto scrubbers, wet vacuums, or similar preparation equipment where necessary.
Proper rinsing and debris removal help improve stain consistency and adhesion performance.
Grinding and Mechanical Preparation
Mechanical grinding may be necessary for surfaces containing adhesives, coatings, uneven profiles, or heavy contamination.
Professional preparation methods may include:
- Initial grinding for surface correction
- Fine grinding for refinement
- Vacuum dust extraction
- Final dry or damp mopping
All dust and debris should be removed completely before stain application begins.
Vertical Surface Applications
Vertical concrete surfaces should be properly cleaned and prepared to allow adequate stain penetration and bonding performance.
Pressure washing may be used on appropriate exterior vertical surfaces to help open surface pores and remove contaminants.
Tape Test for Surface Readiness
A tape test helps determine whether the concrete surface has been cleaned properly before staining.
After cleaning and drying:
- Apply strips of quality packaging tape to multiple areas
- Firmly press the tape onto the substrate
- Remove the tape aggressively
- Inspect for dust or contamination
If visible residue remains, continue cleaning until the substrate is fully free from contaminants.
Mixing and Dilution Guidelines
Smith’s Color Floor and Color Wall products are supplied as concentrates and should be mixed according to the desired appearance and project requirements.
Using distilled, deionized, or reverse osmosis water is strongly recommended because hard water may negatively affect adhesion, color consistency, and long-term durability.
Increasing dilution ratios may create:
- Lighter color shades
- More decorative transparency
- Enhanced mottled effects
- Greater color variation
Lower dilution ratios may improve opacity and surface coverage.
Application Methods
For natural decorative concrete finishes, stain systems are commonly applied using spray equipment that creates a fine mist pattern.
Recommended application tools may include:
- Airless sprayers
- HVLP sprayers
- Pump sprayers
- Trigger spray bottles
- Sea sponges for detail work
- Bristle brushes for edges and decorative finishes
Spray applications help create more natural decorative variation while minimizing visible mechanical lines.
Secondary and Highlight Color Applications
Secondary or highlight colors may be applied after the initial stain coat becomes dry to the touch. Multiple colors can be layered to create decorative concrete finishes with increased depth and movement.
Smith’s Base Boost should only be used for base color applications and should not be added to highlight or secondary color coats.
Application Temperature Guidelines
Proper environmental conditions help improve stain performance and drying consistency.
- Recommended material temperature: 60°F to 90°F
- Recommended surface temperature: 65°F to 85°F
- Recommended ambient temperature: 65°F to 90°F
- Recommended humidity range: 10% to 60%
Lower temperatures and high humidity may extend dry and cure times.
Dry Times and Curing
Under normal conditions, decorative concrete stain systems may become dry to the touch within approximately 20 to 30 minutes. Allowing a full 24-hour cure period before applying protective sealers is strongly recommended.
Proper cure time helps improve adhesion, durability, and long-term coating performance.
Cleanup and Floor Protection
Clean all tools and work areas immediately using clean water while products remain wet.
After staining and sealing:
- Protect floors from heavy traffic
- Use paper or cardboard during construction activity
- Avoid tape on freshly sealed surfaces
- Allow sealers adequate cure time before use
Proper floor protection helps preserve decorative concrete finishes and long-term project appearance.
