How to Step-by-Step
- ProJoint Porcelain Grout should be mixed with 275ml of cold clean water per 1kg of grout.
- Remove the bags from the tub and add the measured quantity of water.
- Slowly add the measured amount of powder.
- Mix for 2 minutes using a drill and mixing paddle or plasterers’ whisk, until a smooth creamy consistency is reached.
- Allow to stand for 2 minutes.
- Re-mix for 2 minutes. This process allows the polymer additives to dissolve and activate. Do not re-wet or add too much water as this may cause a weakening of the grout and may also lead to discolouration in the form of efflorescence.
- Use a rubber float to work the grout deeply in to the joints until flush with the paving. Excess grout should be removed as work proceeds.
- Any final residues left on the tile face can be removed by wiping off with a damp sponge up to 30 minutes after application. Ensure you have plenty of clean water for removing grout whilst wet/damp.
- We recommend the use of a washboy and sponge float to clean the grout residue from the surface of the porcelain and provide a smooth finish on the joints.Textured paving may need additional cleaning to remove once dry. Any dry film remaining on the surface can be removed by polishing off with a dry cloth when the grout has hardened in the joints.
What you’ll need
- ProJoint Porcelain Grout bags
- Cold clean water
- Drill with mixing paddle, plasterers’ whisk or baton
- Rubber float
- Sponge float
- When working outdoors, in warm weather any freshly grouted joints should be kept damp using a fine mist spray.
- The pot life of the mixed grout is approximately 30 to 40 minutes at 20°C.
- All tools should be washed out with water immediately after use.
- Waste material should not be emptied in to drainage systems.
- Newly grouted joints should be protected from rain or frost during the curing process.
- Ensure that any protective cover does not come into contact with the fresh joints; air circulation over joints is required during curing.
How long does it take to cure?
Cure times are dependent on temperature and humidity, but as a guide can accept foot traffic after 3 hours at 20°C and a full cure after 72 hours at 20°C. Please note that cold temperatures can delay the curing time.
