ANSI A118.3-5.1 specifies the water cleanability test for epoxy tile grouts/adhesives, ensuring they can be effectively cleaned with water during installation. Here’s a step-by-step breakdown of the process:
Objective:
To evaluate how easily excess grout can be removed from tile surfaces using water before it hardens.
Test Procedure:
1. Sample Preparation
- Use standard ceramic tiles (as per ANSI specifications).
- Apply the epoxy grout/adhesive over the tile surface, spreading it using a rubber float or trowel.
- Ensure the grout fills the joints properly and covers a portion of the tile surface.
2. Cleaning Process
- After 30 minutes of application, use a clean sponge and water at room temperature (23°C ± 2°C or 73°F ± 4°F).
- Wipe the tile surface gently to remove excess grout.
- Repeat the cleaning process if necessary using only water.
3. Visual Inspection
- After the tile is cleaned and dried, examine the surface for any residual grout/adhesvie haze or staining.
- The grout should be removable with water, leaving no significant haze behind.
4. Acceptance Criteria
- If the grout cannot be cleaned with water within 30 minutes, it fails the test.
- The grout should not leave a permanent residue on the tile surface after cleaning.
