Each 25kg bag of Granatech 40 Fine will yield approximately 13.5 litres of mixed material.

All paving units shall be securely bedded before pointing commences, and all surfaces with which the mortar comes into contact with, 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.

For each 25kg bag of Parex Granatech 40 Fine, a minimum of 4.25 litres of water is required. For single bag mixes, suitable mixing may be achieved using a high torque, slow speed drill with mortar stirrer. For larger mixes, use a standard mixer.

Pour the required quantity of clean, potable water into the mixing vessel. Slowly add the Parex Granatech 40 Fine to the water, continually mixing until a uniformly smooth consistency is obtained (typically, at least 3 minutes is required).

Prior to placing, joints should be wetted but any standing water should be removed. Parex Granatech 40 Fine can be applied to joints of up to 25mm width, however 6 to 15mm is the optimum. The mortar slurry should be placed within 20 minutes of mixing. Continuous placing is important, pouring from one side of the work area, fully filling the joints before starting a fresh section. Parex Granatech 40 Fine 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. Parex Granatech 40 Fine may be placed at temperatures between 5°C and 35°C. For placing temperatures outside this range, contact the Technical Services Department.

In general, no special curing is required, however 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.

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
