+ • • Page 2 • E. Cleaning surface prior to application: Shall be accomplished with either sand blasting, acid washing or water blasting or all of these individu- ally or in combination. Contractor shall have option of cleaning surface in best manner to assure positive adhesion of fiberglass re- surfacing. Execution: Preparation: A. Clean all surfaces to be fiberglassed, existing and repaired, with appropriately diluted solution of acid to remove all rust spots, stains, oils, algae growth or other fozeign materials from areas not completely covered with initial cleaning. Rinse and neutralize with clean potable water and completely remove all residue and liquid from pool bottom or surge gutter or drains. B. Carefully check resulting surfaces of the pool and surge gutter for loose or porous spots or patches of the concrete surface. Repair, seal, and prime any areas which are deficient and not capable of receiving fiberglass coating. C. Undercut and thoroughly clean all underwater light nitches, mechanical fittings, water inlets, recessed bottom drains, and pool anchor devices to insure good adhesion of all materials to be applied under Work of this section. D. Inspect condition of existing and new caulking in both bottom and side wall expansion joints of pool to determine that joints are sound and secure. Use additional caulking, filler or fiberglass reinforcement to level joints with adjacent surfaces. E. At existing and new structural joints or cracks, carefully prime and place reinforcing of 12" wide strips of fiberglass, thoroughly impregnated and rolled tightly into place over the adjacent surfaces. Allow proper curing time but not less than 24 hours. Application: A. Bonding coat: Apply bonding coat-which will act as a primer-to all surfaces which are to be fiberglassed. B. Fiberglass: Apply fiberglass material to a minimum thickness of one- eighth (1/8") inch with the approved integral color using spray equip- ment specifically designated for this type of work. Such as manufactured ~1, by Grayco, or an approved equal pressure method of application, under appropriate environmental and atmospheric conditions of humidity, temperature, etc.. C. Accurately interface with the finish planes of existing surfaces and items, or those installed by other trades. D. Where non-slip surfaces for steps or stairs are required, apply glass beads, non-friable frit, Monterey 100 mesh sieve sand or other approved material compatible with the fiberglass mixture to produce a safe, non- . skid submerged surface for bathers with bare feet.
