CM200 PF Fast Cure is a two-part sealant that is used for several sealing areas. Most commonly used for sealing expansion joints, due to the advantages of the CM 200 PF is can be used for sealing expansion joints in concrete paved areas, docks, container depots, industrial factories, warehousing petrol forecourts. CM200 PF can be cold applied, so ideal for small works, such as remedial re-sealing of joints.
The life of the tin is 20 to 30 minutes at 25C, this is affected, but the outside temperature and the sealant temperature. Final cure, when full working properties are developed, occurs within two days at 25C, although the sealant will normally bear traffic within 2 hours of application. Higher temperature will result in a faster cure time; low temperatures will result in longer cure time. Do not apply at temperatures below 4C.
Ensure that the joint is clean, free from dust and dirt. The joint should also be dry; any contaminant should be removed, the previous sealant, if re-sealing is taking place, must all be removed. If you are backing the joint with backer foam strip, ensure the backer strip is bonded to the base of the joint and proceed to apply. Priming of the surface should be done once the joint is cleaned, the joint faces should be primed with the appropriate primer. CM Primer C is recommended.
Open Pack B and empty the contents into Pack A – Stir for five minutes, preferably using a slow speed electric drill with a mixer paddle, the mix is one. Take care to avoid including excess air. Pour or gun apply immediately into the primed joint. Current practice requires that the sealant shall be poured to a level between 3mm (Summer) and 6mm (Winter) below the wearing concrete surface.
CM Bath & Kitchen is a high modulus silicone sealant that cures rapidly once exposed to natural humidity. Once cured, CM Bath & Kitchens forms to create a permanently flexible, durable weathertight sealant. Along with the flexibility, CM Bath & Kitchen operates within a large temperature range with excellent weathering. CM Bath & Kitchen is a premium silicone sealant product, used for exceptional finishes.
CM Bath & Kitchen meets the standards to BS5889 (1989) Type B and US Fed Spec TTS 001543A (Class A) and TTS 00230C (Class A) and ISO 11600 F&G -25HM 846 food safe.
The uses of CM Bath & Kitchen are but not restricted to the below:
Before the application is made, the required area must be cleaned, ensuring it is dust free, contaminate free, and no loose objects are present. If you are to prime before use, standard primer is advised. If you are re-sealing joints, it is advised that every bit of old sealant is removed to ensure that the joint is contaminant free.
To apply, cut off the top of the cartridge, ensuring it is above the nozzle thread, proceed to screw the nozzle and snipping the top of the nozzle to required joint size at a 45-degree angle. Apply the sealant by gun – place the nozzle angle flush to the joint and extrude a continuous bead. For a neat finish, use a sealant applicator tool kit.
CM Primer C is a single component, solvent-borne, polyurethane priming coat to be used with CM200 PF.
CM Primer C is suitable for priming dry, porous surfaces which form the bonding face of an expansion or construction joint.
Do not use on glazed, metallic or sealed surfaces (e.g. G.R.P. polished stone, painted surfaces etc.)
Once the joint is clean, the joint faces should be primed with CM Primer C using a small paintbrush, ensure that the faces are completely covered. After priming, allow half an hour for the solvent to evaporate. If the application of the sealant is delayed for more than 2 hours after priming, joints should be reprimed.
CM Stonesil is an elastic single-component silicone sealant for indoor and outdoor use, with up to 50% movement tolerance.
The minimum joint size suggested is 5mm x 5mm for internal use and external use 10mm x 8 mm (width x depth). Maximum recommend width of the joint is 30mm x 30mm, but the joint depth should be roughly half the joint width for the ideal seal.
After applying the sealant, it can be smoothed in the joint with water or with a neutral, non-staining water-based smoothing agent and a suitable tool (e.g., Bond-It Applicator Kit). Smoothing the sealant isn’t just recommended for aesthetic reasons, but it will assist in the bonding of the sealant to the substrate.
