VOC Content: 96 g/L
Surface Preparation … Old Concrete: Surface preparation is extremely important. Concrete must always be clean and dry, with all stains, oil, grease, dust, and dirt removed prior to application. If not, they will be amplified by the transparent sheen finish. CAUTION: If a liquid compound other than VOCOMP-20, VOCOMP-25, or VOCOMP-30 has been used, do not apply VOCOMP-25 until all traces of the compound have been completely removed and the surface is clean and dry. New Concrete: Apply VOCOMP-25 when the surface water has disappeared and the concrete surface will not be marred by walking workers.
Mixing … For optimum performance, gentle mixing or agitation is recommended. CAUTION: DO NOT MIX EXCESSIVELY.
Application Method … A typical industrial sprayer, such as a Chapin 1949, provides an easy, economical method of application. VOCOMP-25 can also be applied using a lint-free roller or lambs wool applicator. Care should be taken to maintain a wet-edge during application to prevent roller marks in dried film.
VOCOMP-25 should be sprayed on with a nozzle that produces a flow of 0.1 GPM (0.379 LPM). Spray on in a fine, fog pattern without spurts and dribbles to form a thin, continuous film. AVOID PUDDLING in low areas. If puddles occur, brush or roll them out. For added protection and a greater sheen on new or old concrete, two coats of VOCOMP-25 may be applied at right angles. Additional coats of VOCOMP-25 may be applied after the first coat has thoroughly dried.
Drying Time … VOCOMP-25 dries quickly. Drying times may be extended, depending on application rate, temperature, humidity, and project conditions. Restrict foot traffic for at least four hours. Twelve hours is preferable.
Cleanup … While VOCOMP-25 is still wet, equipment may be cleaned with soap and water. Once dried, the material may be removed with a solvent, such as xylene or toluene.
KEEP FROM FREEZING. Do not dilute. Do not apply VOCOMP-25 when air, material, and surface temperatures are expected to fall below 40° F (4° C) within four hours of completed application. DO NOT MIX WATER-BASED COMPOUNDS WITH ANY COMPOUND CONTAINING SOLVENT.
VOCOMP-25 may be applied to colored concrete, but mottling may occur. Do not use on dense or non-porous surfaces, i.e., brick, stone, etc.
For any alternate specifications or requirements, secure the approval of the manufacturer of any paint, coating, carpet, adhesive, resilient flooring, floor topping, etc. (any type/composition of subsequent floor treatment) that will be applied over VOCOMP-25. Obtain this approval before applying the product over concrete previously applied with VOCOMP-25.
Caution should be taken when applying to dense surfaces. Over-application or buildup of the film may result in the film being scratched by pallets or objects being dragged across it.
HEALTH AND SAFETY
Direct contact may result in mild irritation. Inhalation may cause irritation of the respiratory tract. Refer to Safety Data Sheet for complete health and safety information.
