Chemical Resistance:
- Chem-Screen Topcoat is highly resistant to most common acids, bases and solvents.
- It is the product of choice when the material needs to resist acid and caustic solutions.
Durable:
- Chem-Screen Topcoat will satisfy most industrial demands for a long-wearing, attractive finish.
- This product has excellent abrasion resistance and is ideal for industrial applications where chemical resistance is a concern.
VOC Compliant:
- Chem-Screen Topcoat has nearly zero pounds of solvent per gallon.
- It can be sold anywhere in the country because it applies to all VOC regulations.
Applications & Uses
- Markets
- Surface Preparation
- The most suitable preparation would be a fine brush blast (shot blast) to remove all debris.
- All dirt, foreign contaminants and oil must be removed to assure a trouble-free bond to the substrate.
- Test the surface to make sure concrete is dry by placing a 4" x 4" (1.22 m x 1.22 m) plastic sheet on the substrate and taping down the edges.
- After 24 hours, if the substrate under the plastic is still dry, then the substrate is dry enough to start coating.
- The plastic sheet test is also a good way to determine if hydrostatic pressure problems exist that may later cause disbonding.
- Product Mixing
- Standard packages are in pre-measured kits and should be mixed as supplied in the kit.
- We do not recommend breaking kits down unless suitable weighing equipment or a graduated bucket is available.
- After the two parts are combined, mix well with slow-speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak-free.
- After mixing, transfer the mixed material to another pail (the transfer pail) and remix it again.
- The material in the transfer pail is now ready to be applied on the primed substrate.
- Improper mixing may result in product failure.
- Priming
- A suitable primer should be used before applying this product.
- Without primer, porous substrates may cause outgassing and possible surface defects.
- Product Application
- The mixed material can be applied by brush, roller or spray.
- Or use a serrated squeegee and then backroll as long as the appropriate thickness recommendations are maintained.
- Maintain temperature and relative humidity within the recommended ranges during the application and curing process.
- If concrete conditions or over-aggressive mixing causes air entrapment, then an air release roller tool should be used.
- This product can be used with colored sand in a broadcast system.
- Other suitable aggregates can also be used to achieve a variety of colors and patterns.
- Re-coat or Topcoating
- If you opt to re-coat or topcoat this product, be sure that the coating has tacked off before recoating.
- Colder temperatures will require more cure time.
- Before re-coating or top-coating, check the coating to insure no epoxy blushes (a whitish, greasy film or deglossing) have developed.
- If a blush is present it must be removed with a standard detergent cleaner.
- Multiple coats of this product are compatible.
- Floor Cleaning
- Some cleaners may affect the color of the floor installed.
- Test each cleaner in a small area, utilizing your cleaning technique beore cleaning the entire surface.
