Understanding TEC Unsanded Grout: Choosing the Right One
This guide helps you select the correct TEC unsanded grout for your tiling project, avoiding common and expensive errors. Choosing the right grout is crucial for the longevity and aesthetics of your tiled surface. We’ll focus specifically on tec unsanded grout and its appropriate applications.
What is Unsanded Grout?
Unsanded grout, as the name suggests, lacks aggregate (sand). This characteristic makes it suitable for specific types of tile installations. It’s primarily used for joints that are 1/8 inch wide or less.
When to Use Unsanded Grout
- Narrow Grout Lines: Its smooth texture allows it to fill small gaps effectively without the abrasive effects of sand.
- Highly Polished or Delicate Tiles: Avoids scratching or damaging sensitive surfaces like glass, metal, or polished stone.
- Vertical Surfaces: The absence of sand prevents the grout from slumping or sagging during application on walls.
When Not to Use Unsanded Grout
- Wide Grout Lines: For grout lines wider than 1/8 inch, the grout is prone to shrinking and cracking.
- Areas Subject to Heavy Traffic: Lacks the structural integrity of sanded grout to withstand significant wear and tear.
Why Choose TEC Unsanded Grout?
TEC is a reputable brand known for its quality and consistent performance. Their unsanded grout options offer several advantages:
- Variety of Colors: TEC offers a wide range of colors to match or complement your tile.
- Durability: Designed to resist cracking and fading, providing a long-lasting finish when used correctly.
- Workability: TEC unsanded grout is typically easy to mix and apply, saving time and effort.
Factors to Consider When Selecting TEC Unsanded Grout
Choosing the right TEC unsanded grout requires considering several project-specific factors.
Tile Type
- Glass Tile: Essential to use unsanded grout to prevent scratches.
- Ceramic & Porcelain Tile: Suitable for narrow grout lines (1/16" – 1/8").
- Natural Stone (Polished): Unsanded grout will protect the surface from damage.
Grout Line Width
This is the most critical factor. TEC unsanded grout is specifically for grout lines of 1/8" or less. Using it on wider lines will almost certainly lead to problems.
Color Selection
- Matching: Blends the grout seamlessly with the tile for a uniform appearance.
- Contrasting: Creates a visual separation highlighting the shape and pattern of the tiles.
- Consider the Environment: Darker grout may show efflorescence (a white, powdery deposit) more readily.
Moisture Exposure
While many TEC grouts are water-resistant, assess the level of moisture exposure the tiled surface will experience.
- Showers/Bathrooms: Ensure the selected grout is suitable for wet environments and consider a sealant for added protection.
- Kitchen Backsplashes: Choose a stain-resistant grout that’s easy to clean.

Common Mistakes and How to Avoid Them
Many issues with grout installations stem from improper product selection or application. Here’s how to sidestep the most common problems with tec unsanded grout.
Using Unsanded Grout on Wide Grout Lines
Mistake: Applying unsanded grout on lines wider than 1/8 inch.
Solution: Always measure your grout lines. If they’re wider than 1/8 inch, use a sanded grout.
Improper Mixing
Mistake: Not following the manufacturer’s instructions for mixing. Too much water weakens the grout.
Solution: Use the correct ratio of water to grout powder as specified on the TEC product packaging. Use a mixing paddle attached to a drill for a consistent, lump-free mixture.
Insufficient Curing Time
Mistake: Exposing the grout to water or heavy traffic before it has fully cured.
Solution: Allow the grout to cure for the recommended time (usually 24-72 hours) before exposing it to moisture or heavy use. Check the TEC product data sheet for the specific curing time.
Not Using a Sealant (When Required)
Mistake: Failing to seal the grout in areas exposed to moisture or stains.
Solution: Apply a grout sealant to protect it from water damage, stains, and mildew. Some TEC grouts have built-in sealers, but many benefit from an additional coat.
Choosing the Wrong Color
Mistake: Selecting a grout color that clashes with or detracts from the tile.
Solution: Obtain grout color samples and compare them to your tile in different lighting conditions before making a final decision.
By understanding these factors and common mistakes, you can confidently choose and install TEC unsanded grout, ensuring a beautiful and durable tiled surface.
