Pennkote Pennpool

Primers and sealers shall be pennsealer, pennprimer-metal or pennprimer-bitumen (depending on the substrate) by pennkote limited or pennkote approved alternate. Reinforcing flexible fabric shall be pennflex nylon fabric by pennkote or pennkote approved alternate. Pennflex is available in 45 meter rolls (150') ranging from 100 mm (4") to 1.5 m (5').

• PENNPOOL is specially used as underwater protection for swimming pools, basins, reflection pools, reservoirs, industrial water containers and catchment devices (see limitations). Its inert and non-toxic qualities make it suitable for coating potable water reservoirs, fish ponds etc.
• NOTE: PENNPOOL is a waterbased compound and its drying and concurrent curing time will depend on temperature, humidity, air movement etc. Care must be taken during application under cold, humid and stationary (confined) conditions. Forced air circulation with or without heat may be required to achieve adequate drying conditions.

• PENNPOOL is not to be applied over fresh or lightweight concrete containing moisture or certain curing compounds. PENNPOOL cannot be applied to surfaces that are either wet, oily, frosted, dirty or contaminated in any way.
• PENNPOOL membrane should never be applied over inground concrete pools, reservoirs or other installations subject to continuous or periodical negative water or capillary pressure. Existing installation shall be inspected for presence of cracks, porosity and other defects found in concrete shell as well as evidence of negative water pressure due to improper construction, poor drainage of the surrounding soil etc. prior to application of PENNPOOL.
• PENNPOOL may not be used in direct contact or cleaned with aromatic and aliphatic solvents. Primarily designed as underwater membrane, PENNPOOL is also used in industrial application as chemically resistant tank coating because of its good resistance to most acids and alkalis as well as water soluble inorganic and organic chemicals including alcohols and glycols. Coal tar modified version, PENNPOOL CT offers additional chemical resistance for certain industrial applications.

Elastomeric underwater coating shall be PENNPOOL (specify color) minimum 0.76 mm (30 mil thick membrane) as manufactured by PennKote Limited. Application is to be carried out by skilled applicator approved by PennKote Limited and in strict accordance with manufacturers instructions.

• Surface Preparation: Prepare the surface by removing all loose material, dust, dirt and grease. Heavily contaminated surfaces must be washed repeatedly with diluted muriatic acid and water. All surfaces must be dry. On porous surfaces, apply one coat of PENNSEALER at the approximate rate of 6 to 10 sq.m/liter (300-500 sqft/gallon) On metal, apply one coat of PENNPRIMER-METAL or metal primer approved by the manufacturer, at the rate of 8 to 12sq.m/liter (400-600 sq.ft. per gallon).
• For applications over previously coated pools, all existing paints and finishes (glazing included) should be removed to the soundbonded substrate surface by water-blasting, sandblasting or wire brushing prior to the application of Primer or Sealer. Certain types of coatings if well bonded can be overcoated with PENNPOOL after compatibility and adhesion is positively established.
• Concrete Repairs: Existing porous, weak, loose or deteriorated concrete shall be leveled or repaired with SPEEDCRETE by PennKote or equal material and/or DRYCON & IPANEX "R" by PennKote prior to application of PENNPOOL. Consult appropriate literature regarding details and application of these materials.

• At least two coats are required on all surfaces. Pennpool may be applied by roller, brush, spray or squeegee at the maximum rate of 2 sq.M/liter (100 sq.Ft./gallon). Allow first coat to dry for at least 2 hours or more (see note) before applying second coat uniformly at the same rate. Two coats will upon drying, product a seamless flexible coating approximately 0.75 mm (30 mil) thick. Flashing, cracks, gaps, joints and transitions:
• use pennflex reinforcing fabric. Fabric is centered over joint and rolled into a fresh first coat of pennpool and allowed to dry. A second coat of pennpool is applied over embedded fabric and extended at least 150 mm (6") on each side beyond the fabric edges. Dilution: pennpool is water reducible up to a maximum 10% by volume. Use cool clean water and mix thoroughly until uniform.
• Important: keep from freezing. Do not apply when surface temperature is below 10ºc(50ºf) since all components of pennpool are water reducible, care should be taken not to apply when rain is forecast or a severe drop in temperature is imminent. Do not apply when surface is hotter than 55ºc (130ºf). Clean-up: clean all tools immediately after use with water or soap and water. If dry and hard use varsol or xylene.

Approximately 2 sq.m/liter (100 sq.ft/gallon) for 0.38mm (15 mil) approximate dry thickness per coat. Minimum two coats or, 0.76mm (30 mil) dry thickness is required.
