Marker / Graph Board

  • Product Description:
    Merino Marker/ Graph Marker Board is made with special type of synthetic polymer which imparts durability to surface with easy cleaning of dry erase markers or wet erase markers. Merino Marker/Graph Marker Board Laminate is made with decorative surface papers that are impregnated with melamine resins and pressed over kraft paper core sheets impregnated with phenolic resin. The melamine resin facilitates liquid chalk removal. An assembly of these papers is then placed in a press and bonded under heat and pressure into a thermosetting plastic sheet. Finished sheets are trimmed and the backs sanded to facilitate bonding.

  • Merino Dry Erase Marker Board Laminate is designed for interior vertical use only. Do not adhere directly to plaster, drywall (gypsum board) or concrete. Do not use in areas exposed to temperature exceeding 135°C (275 °F).

    Substrates: Merino Marker Board Laminates are bonded with particle boards or MDF boards. The use of plywood is not recommended due to the potential for surface telegraphing, stress cracking, and shrink-back problems. The substrate should be sanded smooth, clean, free of oil or grease, and uniform in thickness.

    Contact, semi-rigid (PVC) or rigid (urea, resorcinol) adhesives can be used. Always follow the adhesive manufacturer's recommendations. Avoid using combination of substrate and/or adhesive that causes telegraphing.

    Proper bonding recommendations:

    The surfaces should be clean, dry, and free of oils or other contaminants, such as dust, synthetic particles, and so forth. The adhesive film should have full contact with the surface to which it is applied in order to give maximum adhesion
    The adhesive should always be stirred or agitated before use. Sufficient amount of adhesive should be applied on either or both the surfaces to be bonded. When ready for bonding, the spread film of most contact adhesives will exhibit a uniform semi-gloss appearance over the entire surface of the materials to be bonded. Marked variation in appearance will generally indicate an improper or non-uniform adhesive spread. The substrate can generally be seen more readily through those areas where insufficient adhesive has been applied. If this occurs, re-coating the surfaces should achieve a uniform coating. Double coating the edges with adhesive is advisable because of the higher porosity of the substrate edge
    Sufficient bonding pressure to ensure intimate contact is necessary for an adequate bond. Sufficient pressure should be applied over the entire area using as much pressure as possible without damaging the assembly. Pinch rollers (rotary press) and heavy weighted rollers are ideal for such purposes. Hand rolling should be done from the center to the edges to ensure the removal of all air bubbles. The edges should be rolled twice
    Care should be taken to follow the manufacturer's recommendations concerning the allowable tack range of the adhesive. If assembly is made before the adhesive is dry or after the allowable open time is exceeded, the bond may not have satisfactory results
    Unless otherwise indicated by the manufacturer, the temperature of the gluing area and all materials should be maintained around 21°C (70°F) or above
    Experience has shown that when the relative humidity is above 80% at temperatures of 21°C (70°F) or lower, moisture may condense on the surface during drying (known as blushing) and this will prevent an acceptable bond. Hot spray or forced air drying may be used to help prevent this condition
    It is recommended that the maximum sheet size used for vertical field application be limited to 610x2440 mm (2 x 8 ft). If larger panels are required, these should be fabricated in the shop
    A gap of minimum 2 mm should be maintained between two laminates while pasting side by side

  • Storage:
    Sheets should be stored horizontally with the top sheet turned face down and a thick hard board placed on top to protect the material from possible damage and reduce the chances of getting warped. Stored laminate stock should be rotated such that older sheets will be used first. Laminate sheets should be protected from moisture, and should never be stored where they may come in contact with the floor or outside wall. Always carry the sheets vertically. Never slide the sheet but, lift it while moving it from one place to another. We recommend that ideally two people should carry a full size sheet as carelessness can damage the decorative surface.


    Marker board can be cleaned using a felt or multi-purpose board eraser
    In case of marker board when additional cleaning is required, a soft cloth dampened with warm tap water and mild soaps, such as those used for hands or dishes, are recommended. If stubborn stains persist, Marker board laminate can be cleaned with spray-type glass cleaners
    Remember to clean erasers often by wiping to remove dry-erase marker residue
    Do not use cleansers that contain abrasives, acids or alkalis, they will damage the decorative surface
    The boards should be regularly cleaned with moist cloth to remove residues of ink and other chemicals
