  • CM-200-PF

    CM 200 PF Fast Cure

    £55.00

    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.

    Advantages

    • High-performance good movement accommodation, tolerant of severe climatic conditions.
    • Chemical Resistant to spillages of fuels, hydraulic fluids, synthetic and mineral oils, and dilute acids and alkalis.
    • Hand pour or machine/sealant gun application to joint.
    • Non-Toxic Sealant.
    • ISO 9002 Quality Assured Firm -BS5212. 1990 Type N – ISO 11600-F-25LM
    • High Adherence
    • Cure Time 20 to 30 mins.

    Cure Time

    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.

    Preparation

    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.

    CM 200 PF Mixing and Application

    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.

  • bath-&-kitchen

    CM Bath & Kitchen HM

    £5.99

    Details:

    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.

    Uses:

    The uses of CM Bath & Kitchen are but not restricted to the below:

    • Joints in baths and showers
    • General kitchen areas
    • Food prep areas
    • Laboratories
    • High hygiene areas
    • Construction Joints
    • Swimming pools
    • Glass, ceramic or painted surfaces

    Application:

    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

    CM Primer C – 1L

    £19.00

    CM Primer C is a single component, solvent-borne, polyurethane priming coat to be used with CM200 PF.

    Typical Uses

    CM Primer C is suitable for priming dry, porous surfaces which form the bonding face of an expansion or construction joint.

    • To be used on concrete,
    • To be used on cementitious or epoxy mortars,
    • To be used on timber
    • To be used on porous stone surfaces.

    Do not use on glazed, metallic or sealed surfaces (e.g. G.R.P. polished stone, painted surfaces etc.)

    Priming

    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.

    Handling

    • Primer C contains a moisture curing urethane and a hydrocarbon solvent.
    • Harmful – wear PPE when handling, follow safety precautions if inhalation or swallowing.
    • PPE suggestion – suitable gloves and eye/face protection.
    • Do not breathe fumes.
    • Keep away from sources of ignition.
  • CM-SFS-Stain-Free

    CM SFS Stain Free Silicone

    £5.85

    CM SFS Stain Free Silicone is a moisture-cured one-component neutral silicone sealant used mainly for building and glazing joints. With it moisture cure allowing it to cure at room temperature, producing a flexible seal. CM SFS Stain Free Silicone adheres to most common building surfaces without the need for primer. Fully cured movement capability of -/+50%.

    Typical Uses

    CM SFS is designed for jointing or bonding in building and glazing applications such as:

    • Precast panels and curtain wall expansion joints.
    • Windows or doors perimeter joints
    • Aluminium, wood, UPVC glazing joints.
    • Roofs and chimney joints.
    • Venting or gutter joints
    • Bonding mirrors
    • Kingspan panels

    Limits of Use

    • CM SFS is not recommended for use on materials where migration of constituents can take place, e.g. certain rubbers.
    • Not be used for jointing aquariums or swimming pools. Not ideal for permanent immersion.
    • CM SFS, once cured, should not be painted (poor coverage and adhesion of paint).
    • CM SFS is not recommended where abrasion or physical abuse will be encountered.
    • CM SFS must not be used for food contact.
    • When in contact with alkyd paints a slight yellowing can appear on the surroundings of the joint.

     

    Please see the attached datasheet for more information on CM SFS Stain Free Silicone.

  • CM Stonesil

    £5.50

    CM Stonesil is an elastic single-component silicone sealant for indoor and outdoor use, with up to 50% movement tolerance.

    Uses and Application Areas

    • Low modulus non-staining sealant with anti-fungal properties.
    • Fast cure rate.
    • Outstanding UV, weather, and ageing resistance.
    • Adhesion to numerous substrates, such as granite, composite stones, ceramic tiles, brickwork, metals, plastics also compatible with copper.
    • Low modulus (conforms to ISO 11600 F&G 25 LM).
    • Movement capability up to 50% (ASTM C920 class 50).
    • Non-staining (ISO 16938-1, ASTM C 1248).
    • Sealing joints in premier bathrooms & kitchens.
    • Glass to glass joints.
    • Sealing glass to metal.
    • Expansion joints in brickwork/stonework.
    • Marine applications.

    Joint dimensions

    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.

    Tooling

    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.
