Epoxy colored sand is a premium joint filler that combines durability, aesthetic appeal, and eco-friendliness. Perfect for residential, commercial, and outdoor projects, it surpasses traditional grouts with superior moisture resistance, scratch durability, and long-lasting matte finish.

Wanhong Chemical specializes in high-performance coatings and advanced materials, offering epoxy colored sand suitable for kitchens, bathrooms, living spaces, high-traffic commercial areas, and specialized environments. With proper techniques, even DIY users can achieve professional-level results.

Step 1: Prepare Your Workspace and Tools

A clean, organized workspace is essential.

Tools and materials needed:

• Epoxy colored sand (resin + hardener system)

• Low-speed mixing paddle and bucket

• Rubber or silicone trowels

• Protective gloves and goggles

• Measuring cups/scales for accurate ratios

• Damp sponges and clean water

Workspace preparation tips:

• Ensure surfaces are clean, dry, and free of grease or dust.

• Work in a well-ventilated area even though the epoxy is low-VOC.

• Organize materials in the order of use to maintain efficiency.

Pro Tip: Wanhong Chemical’s epoxy sand has a working time of 10–15 minutes at room temperature, so preparation is key.

Step 2: Mixing Techniques with Detailed Ratios

Accurate mixing ensures consistent color and optimal performance.

Example ratio (per Wanhong Chemical guidelines):

Mixing Steps:

1. Combine resin and hardener in a bucket.

2. Stir with a low-speed paddle for 2–3 minutes until fully blended.

3. Gradually add colored sand, mixing thoroughly to coat each grain evenly.

4. Check consistency: thick but spreadable.

Tip: Work in small batches for large projects to prevent premature curing.

Step 3: Installation Guidelines

1. Press mixture into joints with a rubber or silicone trowel, ensuring complete fill.

2. Scrape excess material immediately to avoid hard-to-remove residue.

3. Work section by section for better control.

4. Corners and edges: compact mixture to prevent gaps and air pockets.

Illustration Suggestion: Use a diagram showing step-by-step joint filling, troweling, and smoothing.

Step 4: Finishing for a Professional Look

• Smooth surface with a damp sponge.

• Wipe surrounding surfaces immediately.

• Allow 24–48 hours curing.

• Optional: Light buffing to enhance matte finish.

Pro Tip: Wanhong Chemical’s epoxy sand prevents the “plastic look” common with glossy sealants.

Step 5: Color Selection Guide

• Solid Colors: Neutral tones for minimalist or classic interiors.

• Blended Effects: Combine multiple shades for decorative patterns.

• Custom Mixes: Adjust resin-to-pigment ratio for desired hue intensity.

Tip: Test on a small area before large-scale application.

Step 7: Maintenance Tips
