To optimize the chemical properties of Acrysirup, after mixing the hardening agent a number of things must be observed to ensure that the curing reaction proceeds quickly and thoroughly and to ensure that free radicals are generated and air blocked off. Failure to observe these points can cause incomplete curing, peeling, floatation, and other defects. Be sure to observe the following when applying Acrysirup. 1. Substrate (concrete)   �@ Cleaning with a broom or vacuum cleaner is insufficient; cleaning must also remove any laitance that has occurred in the substrate.   �A Do not use polymer cement mortar.   �B Do not apply to newly built substrate until the surface is thoroughly dry. 2. Treating the substrate   �@ Even a repaired substrate that is firm and smooth requires treatment; apply treatment appropriate to the substrate type.   �A Do not apply when the substrate is wet; dry the surface before applying.   �B Do not apply before removing substances such as oil, paint, rubber, and grime from the surface. 3. Temperature range when applying   �@ Standard grade Acrysirup resins will not cure on a substrate with a temperature of 30oC and higher. To reduce temperature, block the sun with a sheet, apply at night, or apply a summer-grade Acrysirup.   �A Standard-grade Acrysirup resins will not cure on a 0oC or below substrate without an accelerant. When applying to substrates in this temperature range use with DR-AC-102 accelerant. 4. Adding hardener   �@ Curing will be unsatisfactory if an insufficient amount of hardener is added; add hardener in accordance with grade and temperature.   �A Do not visually measure hardener amount; precisely measure with a 1kg measuring instrument. 5. Acrysirup methalmethacrylate resin . Always thoroughly shake the container before measuring Acrysirup; after the wax is thoroughly diffused break up into smaller portions and measure. 6. Mixing   �@ Always thoroughly mix Acrysirup and filler; inadequately mixed portions will not cure properly.   �A Do not mix filler into Acrysirup before adding hardener; always add hardener before mixing in filler. 7. During application   �@ Do not apply in sealed-off or poorly ventilated rooms; always use a ventilation fan or other air circulation device to replace indoor air with outside air.   �A Do not use paint thinner or lacquer thinner when cleaning brushes, trowels, containers, and other implements because thinners impede curing. When cleaning implements, use the special cleaner Acryester M.   �B Always properly dispose of used Acryester M. Mix with Acrysirup, add hardener, and after the material hardens dispose in a manner appropriate for an industrial waste product. 8. Checking coated surfaces . If after application the surface is not firmly cured after one hour of light exposure, the surface is not properly cured. If this occurs, remove the surface and repeat the procedure. 9. Storing materials   �@ Do not store exposed to sunlight. Store in a dark, cool place.   �A Do not use hardener that has yellowed. Yellowed hardener has lost effectiveness.
