ELAS TOROOF P.U. ONE COMPONENT ELASTOMERIC MEMBRANE
PRODUCT DESCRIPTION ELASTOROOF is a single component moisture curing tar extended polyurethane liquid applied elastomeric membrane for waterproofing and protection of a wide range of surfaces. The product cures to a tough rubber like finish with exceptional elasticity which allows for expansion and contraction over a wide range of temperatures. ELASTOROOF provides complete, seamless, waterproofing membrane free from joints replacing asphalt systems and self-adhesive asphalt membranes. ELASTOROOF has excellent bonding to substrate, thus, water cannot travel beneath the membrane even if accidentally punctured. ELASTOROOF is simple to apply by brush, roller or spraying application straight from the pail. ELASTOROOF may be applied to horizontal surfces without without additional additional thinner. On vertical vertical surfaces it should be applied in multiple coats. A non sag grade is available where coating of extensive vertical areas is required. BASIC USES ELASTOROOF is ideally suited for the waterproofwaterproofing of two course concrete slab construction for parking garages, decks, shopping malls and plaza areas, bridge decks, elevated side walks and roadways or in single course construction for waterproofing tunnels, foundations, planters and base slabs in terrazzo and quarry tile floor installation and also as a waterproofing between the structural slab and concrete topping of roofing system and under flashings. Long term of continuous water submersion does not affect ELASTOROOF adhesion to the substrate. Under such conditions, two part epoxy primer is to be used prior to applying the membrane. LIMITATIONS ELASTOROOF is not designed for and may not perform under the following conditions or circumstances: ELASTOROOF is not to be used as a finishing traffic surface. The membranes not to be exposed to UV rays or to sunlight, direct or indirect due to the possibility of a color change in the membrane which may be objectionable. ELASTOROOF can be covered with CEMTEC ELASTUFF 103, a U.V. resistant P.U. waterproofing Top coat. Certain curing compounds and chemical additives in concrete can have an adverse effect on the
bond of ELASTOROOF . A field test should be conducted under these conditions. Do not apply ELASTOROOF over light weight concrete without prior approval from CMCI’s Technical Services Department. Steel-pan decks must be vented with 1/4” boles at 4” centres. Do not apply on excessively hot decks. COLOR PACKING

INSTALLATION Preparatory work: All surfaces must be smooth, dry, dry , firm and free of voids, projections, lose materials, materials , oil, grease curing compounds and other foreign matter. Concrete decks should be cured a minimum of 7 days (Preferably 28 days) before applying membrane. High, early strength and insulating concrete do not provide suitable substrates. ACI-301-1104(B), Floatfinished surfaces, should be considered as the minimum finish for best results. Application: ELASTOROOF while designed primarily for horihorizontal applications with its self-levelling characteristics, may be applied to vertical surfaces with a roller or suitable spray equipment. However, it will be necessary to make several coats to buildup the desired thickness. thickness. An application application of 40 mils thickness is recommended for horizontal surfaces. Do not apply membrane unless the ambient temperature is at least 40oF and rising. Catalyst: Although ELASTOROOF attains a relatively fast cure, a special catalyst, urethane accelerator, may be added to reduce the curing time if humidity is low or if early rainfall is anticipated. In the uncured state, light rainfall will not cause physical or chemical damage to ELASTOROOF, ELASTOROOF, however, heavy rainfall may cause such physical damage that the material will have to reapplied. ELASTOROOF may develop blisters or bubbles bubbles when applied to concrete having a relatively rough finish or sand pits. This can be minimized by applying a prime coat of ELASTOROOF that has been diluted with Toluene Toluene or Xylene Xyl ene in equal parts. part s. Allow the primer coat to cure before applying the finish coat.

MAINTENANCE If the membrane is damaged and the bond is intact, cut out damaged area and recoat. No primer is required. If the bond is affected, remove the membrane, clean and prepare in accordance with the instructions under “Installation”.
Cleaning: Tools and equipment may be cleaned using MEK, Toluene or Xylene. Storage Life: ELASTOROOF is stable for a period of 6 months after manufacture, when stored in the original unopened containers under a protective roof or cover at temperatures not exceeding 80 Deg. F Precautions: ELASTOROOF contains diisocyantes and is harmful if swallowed. Avoid prolonged breathing of vapors and contact with skin and eyes. Wash hands thoroughly before eating or smoking. Upon accidental contact with eyes, flush with water and seek medical attention at once. Wear protective clothing and use soap and water to remove material from skin.
