Gem Finishes, Gem Finishes, the etch resistant marcite alternative, are a mill prepared marcite alternative blended with the highest quality selected colored quartz aggregates, white portland cement and proprietary additives to enhance strength, density, bonding and curing. A Gem Finish will yield a hard, long lasting surface highly resistant to stains and spot etching prevalent with traditional pool plasters. Exposure of the aggregate produces a safe, slip resistant and non-abrasive surface that attains a compressive strength in excess of 3500 psi in 24 hours and exceeds 7000 psi in 28 days.
Surface Preparation
Suitable for application over gunite or shotcrete substrates which are free of foreign matter, e.g., dirt, grease, oil, dust, etc. If an acid wash is used to rid the substrate of foreign matter, neutralize with a solution of soda ash and water. If the project is a renovation, Florida Stucco's POOL PREP is an excellent preparation material to be used in conjunction with a Gem Finish. Consult our specifications regarding POOL PREP for additional details. Roughening the pool base cement surface provides a good basis for the mechanical bonding of the base to the Gem finish. Previously finished surfaces can be made suitable for re-finishing by sandblasting, hydro-blasting, or by applying acid. Existing plaster should be chipped away below the tile line for 2" - 4", and around return outlets, pool lights and main drains.
Mixing Procedure
Use only clean, potable water. WATER MUST BE CAREFULLY MEASURED FOR EACH BATCH - UTILIZATION OF A MEASURING PAIL IS HIGHLY RECOMMENDED. Approximately 1.5 to 2 gallons of water per 80-pound bag can be used to bring the mix to a lump-free consistency. Allow the mix to agitate in the mixer for 10-12 minutes to provide best workability. The Gem Finish is a complete product; addition of other materials is not necessary.
Application
Apply Gem Finish over a cement base that has been dry for a minimum of 24 hours. The pool's walls and floors must be evenly sprayed with water before application to reduce suction. Gem Finish should be applied to a thickness of 3/8" to ½". Application is best accomplished by mechanics that adhere to the professional standards of the plastering industry.
Exposing Gem Finish
Depending upon prevailing weather conditions, exposing the Gem finish can begin shortly after trowelling. Removal of surface layer cement can be accomplished with water and a soft bristle brush. Other industry accepted methods can be used as well.
Curing
Filling the pool with water may begin upon completion of the exposure phase. Refer to the National Plaster Council Start-Up Procedures immediately after filling the pool with water.
Coverage
Florida Gem Finish will yield approximately 20-22 square feet of material per 80-pound bag.
Precautions to be observed
This product is portland cement based and can cause skin or eye irritation. Any skin or eye contact with this product should be immediately washed with plenty of fresh water. Wearing of a respirator is recommended when using this product. Please review product MSDS for further information.
