Application
SURFACE PREPARATION
Test panels should be made on specific jobs to ensure use of proper sealer and to determine the number of coats required. Surface must be clean, dry, structurally sound and free of foreign matter such as grease, oil and dirt. Unitex CITRI-CLEAN may be used as a degreaser, followed by a thorough rinse with clean water. Surface should be dry prior to application. Cracks, expansion joints and spalling should be repaired before sealing.
METHOD
Apply with Chapin sprayer to form a light continuous film.
APPLICATION
Stir before spraying. Spray in a cross-hatched, continuous light film to the point of rejection, avoiding puddling. Two light coats are preferable to one heavy coat. Second coat may be applied in 4 hrs. if additional gloss is desired. Avoid over-application and high gloss which may become slick and discolor. |

Limitations
To avoid possible haziness on colored concrete, application should be made a minimum of 24 hrs. after pouring concrete.
Test panel should be made on specific jobs and left for the amount of time specified by the architect to ensure use of proper sealer and to determine the number of coats required.
Minimum application air temperature is 40°F/4°C
Never apply to frozen concrete even if the air temperature is 50-60°F/10-16°C.
Will not provide bond to cementitious adhesives.
Provide adequate ventilation during application. Use of a NIOSH/MSHA organic vapor respirator is recommended if ventilation is inadequate. Do not apply in inhabited buildings where application odor may be objectionable. Once dry, product is odor free.
Do not apply where food is stored as it may absorb solvent odor. Once dry, product is innocuous.
Not for continual immersion in water or around fountains.
Not recommended on colored concrete except that which binds exposed aggregate.
Not for steel troweled exterior concrete as sealer may cause surface to be slippery. |
