Dampen the paving slabs before starting the job. Open one
bag at a time, empty a small amount and immediately brush
Joint Tec into the joint, then repeat until jointing is complete
with the next small amount. Do not rub the product into the
paving surface. Once filled, we recommend compaction
using a pointing iron or other suitable tool.
• On very porous surfaces such as Indian Sandstone ensure
surface is kept damp during application. Do not allow
surfaces to dry as some temporary staining may occur.
• Paved areas and joints must be well drained, to avoid
standing water in joints for long periods.
• A trial should always be carried out prior to full scale
application.
• Due to the nature of Joint Tec, there are occasionally small
lumps within the bag due to compaction. If these can
be easily broken up by hand, it is suitable for use.
• Hard lumps in the bag, greater than 50mm diameter, indicate
that the oxygen barrier within the bag has been broken and
therefore product should not be used.
• Depending upon the porosity and type of paving, variations
in the colour and texture of the paving may be highlighted.
This will diminish over time, dependent upon weathering,
exposure and traffic. Some natural stone can be susceptible
to long term staining from all types of joint fillers, including
sand/cement mortar. We recommend a trial in a small
inconspicuous area or on a piece of scrap paving prior to
application to ensure that it does not stain light coloured
paving.
• Joint Tec will start to set immediately and be capable of
taking light traffic 6-12 hours before 15°C in dry conditions.
• Allow up to 4 days for full set in temperature between 4°C
and 15°C. Contact with rain or moisture can slow the final set.
