View ProductMethod of Application
A comprehensive, sequential procedural view designed for engineers and site applicators to attain faultless surface integration using LX-7 adhesive compounds.
Surface Preparation
Remove all Dust, Water, Oil & Sealers from Surface / Substrate to ensure full chemical contact.
Water Addition
Add 5 to 6 Liters of clean water or Admix into an empty structural mixing bucket.
Adhesive Mixing
Add 20 Kg LX-7 Thin Set Adhesive into water and mix thoroughly until it attains a perfect, uniform paste.
Slaking Period
Allow the mixed material to slake (rest) for 5 to 10 minutes to fully activate its polymer bonding properties.
Re-mixing
Mix the material again briefly without adding extra water, then transfer the material onto your notch trowel.
Flat Bedding
Use the flat side of the trowel to spread and press the adhesive layer uniformly onto the base substrate.
Adhesive Combing
Comb through the adhesive layer at a precise angle with the help of a correctly sized Notch Trowel.
Back Buttering
Spread the adhesive material on the backside of the tile also if the tile dimension is larger than 12\"x12\"."
Leveling
Press and tap the tile surface gently with the help of a Wooden Hammer to maintain a perfectly uniform surface plane.
Surface Cleaning
Clean the tile surface thoroughly using a clean wet cloth or damp sponge before the compound sets.
Curing Phase
Restrict all foot traffic completely across the layout zone and wait up to 24 Hours for full chemical curing.
Final Grouting
After completing the 24 Hrs wait period safely, you can immediately proceed with filling joints via the grouting process.
Installation Instructions
Before you begin
- Ensure all surfaces are between 50°F (10°C) and 100°F (38°C).
- Verify the surface is structurally sound, clean, and free of dirt, oil, grease, paint, laitance, concrete sealers, or curing compounds.
- For very large format tiles: Remove any demolding wax powder on the back of the tile and any fiber mesh present.
Before you begin
- Ensure all surfaces are between 50°F (10°C) and 100°F (38°C).
- Verify the surface is structurally sound, clean, and free of dirt, oil, grease, paint, laitance, concrete sealers, or curing compounds.
- For very large format tiles: Remove any demolding wax powder on the back of the tile and any fiber mesh present.
Surface preparation
- Floors: The substrate should not have a variation exceeding 1/8" in 10 feet (3 mm in 3.05 m) or 1/16" in 24 inches (2 mm in 600 mm) when measured from high points.
- Walls: The prepared substrates should not have a variation exceeding 1/8" in 10 feet (3 mm in 3.05m) when measured from high points.
- Dampen dry, dusty concrete slabs or masonry and sweep off excess water before installation.
- New concrete slabs must be damp cured and at least 28 days old before installation.
Suitable bonding surfaces
- Concrete or plaster that fully cured and absorbs water (tested by sprinkling water).
- Properly cured lightweight cementitious systems that are dry and meet manufacturer specifications.
- Cutback adhesive residue must be removed by wet scraping before installation.
Movement joints
- Install movement joints around the perimeter and other plane changes.
- Expansion joints in the substrate must be continued through the tile work.
Mixing gresbond lx-7
- Use clean water and GRESBOND LX-7 S1 powder in a ratio of 5.0-5.5 L water per 20 kg powder.
- Mix with a low-speed drill mixer until a smooth, paste-like consistency is achieved.
- Let the mixture stand for 03-05 minutes, then stir again before use.
- The mixture should hold troweled ridges without slumping when properly mixed.
Applying gresbond lx-7
- Suitable Trowel: Use a properly sized notch trowel to ensure complete tile coverage.
- Tile/Stone Application:
- Apply a skim coat of mortar to the surface using the flat side of the trowel.
- With the notched trowel held at a 45° angle, comb additional mortar onto the surface in one direction.
- Press the tile firmly into the mortar, moving back and forth to flatten ridges and ensure maximum coverage.
- Adhesive mortar should not be used to fill low spots in the flooring. The mortar thickness should not exceed the specified range.
- Back-buttering is mandatory for all large format tiles.
- Glass Mosaic Tiles:
- Apply the adhesive with a scraping motion using a notched trowel with 4mm notches for a 1.5-2 mm bed thickness.
- Setthe tiles and gently tap them with a mallet to ensure full bedding.
- After the tiles are firm, dampen the face of the mosaic sheets and remove the paper backing.
- Wood Substrates: Use GRESBOND EA-100 for tile or stone installations.
Additional tips
- Use a mechanical edge-leveling system to minimize lippage during installation.
- Lightly tap the tile surface with a rubber mallet to ensure good contact with the mortar bed.
- Clean tools with water before the material dries.
- Store GRESBOND LX-7 S1 in a cool, dry area.
Grouting
- Grout installation should commence after a minimum of 24 hours of curing time at 70°F (21°C).
- Use Gresbond Unsanded Grout mixed with Gresbond Grout Admix-KGA-01.
- For maximum stain resistance of internal spacer joints applications, use Gresbond KE-100 Stainfree Grout.
Suitable Substrates
Concrete
Cement Mortar Beds
Cement Plaster
