PRODUCT DESCRIPTION
PERMASEAL Solvent-Free (SF) is a clear, UV light-stable
solution designed to penetrate and stabilise the jointing sand of block
paving to inhibit the growth of weeds and moss and eliminate sand loss.
PERMASEAL SF will also seal the block paving to enhance the appearance
whilst facilitating the easy removal of oil and other stains.
PURPOSE
PERMASEAL SF has been designed to protect jointing
sand from erosion thus eliminating movement and weed infestation in block
paved surfaces. In addition it can improve the aesthetic appearance of
blocks, paving slabs and other cementitious substrates and increase abrasion
resistance.
SPECIAL PROPERTIES
- Eliminates sand loss from joints
- Reduces efflorescence
- Ultraviolet light and weather resistant
- Inhibits the growth of moss and weeds
- Excellent resistance to water whitening
- Enhances the colour of the paving
- Facilitates the easy removal of oil and other contamination
- Will not blister or peel
PACKAGING
25 litre U.N. approved drums
COVERAGE
Approximately 3m2 per litre - in one or
two applications, depending on the block porosity and joint size.
HEALTH & SAFETY
PERMASEAL SF is nontoxic and nonflammable. Avoid
contact with skin and eyes. Flush affected areas with water. Do not take
internally. Refer to Health & Safety data Sheet for further information.
PREPARATION INSTRUCTIONS
New block paving should be swept clean, ensuring there
is sufficient well-compacted sand in the joints. Existing paving should
be pressure-washed to remove all surface debris. If the area is contaminated
with weeds and moss then it should be treated with PICS Fungicidal Wash.

|
Oil and other stains should be removed using PICSCLEAN
degreaser. The treated area should then be left to dry and the joints
re-sanded and compacted to the lower edge of the paver chamfers with clean
kiln-dried sand. Moisture in the paver and sand will inhibit penetration
of the sealer.
APPLICATION INSTRUCTIONS
PERMASEAL SF can be applied using spray or squeegee
at a rate of 3m2 per litre to an easily managed area not exceeding
10m2 at any one time. In the event that two applications are
required the second application must be applied prior to the first application
becoming tack-free. PERMASEAL SF should be used in dry weather
when rain is not forecast. Do not return unused material to its container
as this may cause contamination. PERMASEAL SF will be tack-free
after two hours at 20°C and foot traffic may be permitted after 12
hours. Vehicles should be kept off the treated area for a minimum of 24
hours at 20°C. These times may be increased or reduced depending on
the ambient temperature. During the drying cycle protect from rain. Do
not apply when the ground temperature is above 30°C or below 5°C.
Clean all equipment after use with clean water.
TEST DATA
PERMASEAL SF has been tested for chemical resistance
by one hour exposure to a range of substances, including used motor oil,
deionised water, 10% sodium hydroxide, sodium chloride, calcium chloride,
trisodium phosphate, ammonia and hydrochloric acid, all with no effect.
