Polyurea Tile Grout Construction Step 1 -- Clean Gap

Preparation Tools

Blade Scraper, Hook Cutter Knife, Blade Cutter Knife, Knife Blade, Sanding Sponge

When installing the blade into Blade Scraper, the blade protrudes 5 mm. The Blade Scraper clean the gaps at 45 degrees with the left and right sides to ensure that cement, dust and various impurities inside gaps are clean, and ensure that there is no debris adhering to both sides of the tiles. The Cross Buckle need to be hooked out with the Hook Cutter Knife. The gap-cleaning depth is more than 5mm.

Polyurea Tile Grout Construction Step 2 -- Deep Clean & Vacuum

Preparation Tools: Broom, High-power Vacuum Cleaner

First, use the Broom to sweep the entire house, then use a High-power Vacuum Cleaner to vacuum the gaps.

Note: If the gaps are not cleaned enough, it might cause the Polyurea tile grout has bubble or fall off.

Polyurea Tile Grout Construction Step 3 -- Wipe Gap

Preparation Tools: Mop, Fish Scale Cleaning Cloth, Knife Blade, Water

There are two steps for wiping gaps. Firstly, use a damp Fish Scale Cleaning Cloth to clean the gaps and surface of tiles to avoid dust during construction. Secondly, use Knife Blade wrapping the semi-damp cloth to wipe the gaps. Make sure that wipe totally clean without leaving any dust or water stains

Polyurea Tile Grout Construction Step 4 -- Wax

Preparation Tools: Wax for Grouting

The construction of Polyurea tile grout requires waxing, and the kind of wax should be matched with the grout. Do not get the wax into the gaps. Wax inside the gaps will easily cause the grout to fall off.

Note: When waxing, if the wax gets into the gaps, it will easily cause the grout to fall off and crack.

Polyurea Tile Grout Construction Step 5 -- Inject Grout

Normally, the Polyurea grout does not need to be heated. If it needs to be heated, the water temperature should not exceed 50 degrees Celsius.

If heating with water, the Tube Top should be put downward, and the water level should not exceed the end of the Tube to prevent water from entering into the Tail Plugs.

When cutting the two Extruding Points, they should be cut at the same size to ensure the same amount grout can come out from both sides.

Inconsistent cuts will cause AB components mixing ratio is uneven and the grout does not cure after applying.

The width of opening of the Mixing Nozzle according to the width of tile gap.

Before install the Mixing Nozzle, squeeze out little grout to ensure that A&B component can come out at the same time.

After install the Mixing Nozzle, squeeze out and discard about 20cm to ensure uniform mixing of A&B.

If use an Electric Caulking Gun, set the speed less than 3 gears.

When squeeze and inject grout, the Caulking Gun should be raised a little, with an angle more than 70 angles, controll the speed less than 3 gears, squeeze and inject slowly, evenly fullfill into gaps.

During the construction, you must walk backwards at a constant speed. If there is a pause for more than 5 minutes, you need to queeze out and discard a section grout before continuing the injecting.

During the construction, if the pause exceeds 10 minutes, the grout inside the Mixing Nozzle might be cured, try to change a new Mixing Nozzle.

Note: If the Polyurea tile grout is not constructed according to above guidance, it will cause non-curing or uneven curing after construction.

Note: When injecting grout, the thickness must be uniform to avoid the problem of bulging and collapse.

Polyurea Tile Grout Construction Step 6 -- Separate Grout

When separating the injected grout, the angle between the Pressing Ball and the tiles surface needs to be larger than 50 angles.

Make sure press grout along the gaps at a constant speed and slowly. Do not press the gaps quickly, and ensure that the grout is completely pressed into gaps rather than thrown out away from gaps.

Note: If the speed of pressing grout is fast, the grout will be squeezed to both sides instead of pressed into the gaps.

Polyurea Tile Grout Construction Step 7 -- Clean Residue

After the grout is completely cured, you can clean up the remaining residue materials. The first step is to inspect to see if there is construction defect. Mark the defective areas in time and wait for the second inspection to repair them.

Polyurea Tile Grout Construction Step 8 -- Inspection & Repair

After cleaning up the remaining residue materials, carefully conduct a second inspection throughout the whole house to see if there is defect. If there is, use a Blade Scraper to clean it out. Use the Textured Paper to paste tiles gaps both sides and then press the injected grout.

Note: Pay attention that the grout interface is connected with an angle, not straight, so that the repaired grout will be more natural.

Polyurea Tile Grout Construction Step 9 -- Completion

After the gaps repairs, clean up all remaining materials. Use a wet cloth or Mop to clean the entire house before handover.
