How to Use Forti-Grout

Grouting pinholes (up to 3mm) & hairline cracks:

• Mix well before use.
• It is recommended to grout min 4 hours after your first saturation densification.
• You can use 80 to 150 grit metal pads to grout if you are aiming for a cream finish.
• Spray Forti-Grout™ generously for only 1.5m in front of the grinder (it dries fast).
• For better colour matching lightly sprinkle some cement powder over it and broom in quickly.
• Don’t delay – grind over it while it is still damp – it dries quickly. If grout is sticking to diamond pads, increase rotational speed.
• For edges apply grout with a paint brush 1 metre in front of the hand grinder. Use a variable speed grinder with a 100 grit soft bond cup disc.

Patching wider cracks and larger holes (more than 3mm):

• Mix Forti-Grout™ with ready mix cement mortar, which matches the colour of the slab.
• Use the same quantity of Forti-Grout™ as recommended quantity of water. For e.g. if cement requires 100mL of water, use 100mL of Forti-Grout™.
• Use a suitable spatula to slightly over fill holes and cracks, as it will shrink and also so you can grind it down to slab level so it is flat and seamless.
• Give filled areas at least two hours to partially harden before grinding. Heater can be used to speed curing.

Filling sandy areas around large aggregate:

• When very porous large aggregate is used in concrete, water & cement can penetrate into the stones leaving a sandy, rough area around each stone.
• Use Forti-Grout™ to fill these areas, NOT densifier, because with little calcium hydroxide in sandy areas, the densifier remains highly water soluble and will wash out over time when floor is cleaned.
• Lightly sprinkle some ready mix cement powder / mortar over it and broom in quickly.

Clean-Up and Appearance

• Clean tools with water.
• Colour: Milky white liquid
