Features & Benefits

• Uses:
  • Grouting large areas
  • Laying cropped setts
  • Suitable for pedestrian traffic at 2hrs
  • Suitable for vehicular traffic at 6hrs
• Quick to apply
• High strength
• Economical & cost-effective
• Aesthetically pleasing finish
• Can be applied speedily over large areas for effective jointing of all paving units, providing quick and cost-effective jointing when laying wherever there is a large proportion of jointing material to paving unit
• Specially formulated to meet the requirements of architects and engineers requiring compliance with the relevant part of BS 7533 and BS 1881

Preparation

• All paving units shall be securely bedded before pointing commences and all surfaces with which the mortar comes into contact clean and dust-free
• A strong mortar bedding, free of all friable material, will enhance bond strength
• Ensure that enough mortar is mixed and available for the grouting operation to be completed in one continuous pour

Mixing

• For each 25kg bag of Granatech, 4.25 litres of water are required
• For single bag mixes, suitable mixing may be achieved using a high torque slow speed drill with a mortar stirrer
• For larger mixes, use a standard mixer
• Pour the required quantity of clean water into the mixing vessel
• Slowly add the Granatech to the water, continually mixing until a uniformly smooth consistency is obtained
• Each 25kg bag of Granatech will yield approximately 13.5 litres of mixed material

Placing

• Prior to placing, joints should be wetted but any standing water should be removed
• Granatech can be applied to joints of up to 25mm width however, 6-15mm is the optimum
• The mortar slurry should be placed within 30 minutes of mixing
• Continuous placing is important, pouring from one side of the work area, fully filling the joints before starting a fresh section
• Granatech may be poured over the paving units safely, though it is essential to dampen their surface prior to the commencement of application
• Once placed, the mortar should be left to stand until it gels, prior to the commencement of cleaning, though the surface must be kept damp during this time by the application of a light spray of water as required
• Once the mortar has gelled, finishing and cleaning to remove any surplus material can proceed using either a proprietary belt cleaner or a soft brush together with a continuous light spray of water
• Granatech may be placed at temperatures between 5°C and 35°C

Curing

• In general, no special curing is required
• In extremely warm conditions (>25°C) it may be necessary to continuously spray the placed area with water to aid curing and prevent the material from drying too fast
