Usage
Quickmast 108 is a permanent epoxy adhesive for bonding fresh wet concrete/cementitious material to old concrete/cementitious surfaces, which is suitable for internal and external application. Materials SuppliedQuickmast 108 is available in 1 and 5 kg packs Coverage
3.0 – 3.5 m²/kg.
Storage/ Shelf Life
Quickmast 108 has a shelf life of 12 months from date of manufacture if stored at a temperature between 5°C and 25°C.
If these conditions are exceeded, DCP Technical Department should be contacted for advise. RemarksIf
temperature of the material is less than 12°C, it is needed to
elevate their temperature to 25°C before the application. And if the ambient and the substrate temperature is less than 5°C, don’t use the material.
Also,
at high temperatures (35°C and above), cooling the material is
needed before the application. And try not to make the application in the
middle of the day or under direct sunlight. StandardQuickmast 108 complies with ASTM C881, Type II, Grade 2, Class C. |
Technical Information
Application InformationSUBSTRATE PREPARATION
The substrate should be
sound, clean and free from contamination. Surface laitance should be removed by
acid etching or light grit blasting. Oil, grease, and fat deposit should be
removed by using either appropriate degreaser or steam cleaning. Weak or deteriorated
concrete should be removed by scabbling, chipping or grit blasting. The base and the hardener
should be mixed separately before mixing together to disperse any settlement.
Carefully transfer the entire contents of the hardener container into the base
component container and thoroughly mix using slow speed drill with appropriate
mixing paddle for 3 minutes until uniformity is obtained. Do not attempt to mix
partially nor add any thinning materials. Quickmast 108 is designed to have
an overlay time of 18 hours at 25°C, 8 hours at 35°C and 3 hours at 45°C. This
should allow for subsequent works such as steel reinforcements fixation and
shutter erection. APPLICATION Quickmast
108 should be applied immediately after mixing using a short haired paint
brush. The
material should be painted evenly across the whole surface and left for at
least two hours or until it become tacky before the new concrete, screed or
mortar is placed. Care
should be taken to apply the new concrete, screed or mortar within the overlay
time specified in Technical Properties. Failure
to do so will have an adverse result and the material will form a de-bonding
plane rather than a bonding coat. Minimum
application temperature is 5°C while temperatures exceeding 35°C will decrease
pot life and setting time.
