Surface finish and level of sheen are dependent on the application method. Avoid using a combination of application methods whenever possible. A superior esthetic appearance will be obtained with airless spray application. Condensation occurring during or immediately following application may result in a matte finish.
If overcoating Si-COAT 531AG after prolonged weathering or aging, ensure the coating is fully cleaned to remove all surface contamination such as dust, grease, oil, salt crystals, traffic fumes, etc. before application of a further coat of Si-COAT 531AG.
Do not apply to substrate temperatures below 41°F (5°C). When applying Si-COAT 531AG in confined spaces ensure adequate ventilation and/or respiratory equipment is available. Consult the Si-COAT 531AG SDS for further details.
Si-COAT 531AG has excellent tolerance to airborne chemical exposure. When severe chemical or solvent splashing/pooling is likely to occur please contact CSL Silicones Inc. for information regarding suitability.
- Benefits
- Easy application – single coat spray application with minimal site preparation.
- Cost effective – less labor and application costs due to simplicity of use.
- Versatility – Use on metal, concrete, brick, stone, wood, fiberglass and pre-existing coatings.
- Superior Performance – Graffiti can simply be washed off using a pressure washer and/or water and a soft bristle brush. No harsh chemicals necessary.
- Durable – long lasting, withstands many graffiti removal cycles, UV resistant.
- Esthetically pleasing – will not damage pre-existing coverings nor peel.
- Quick Dry Time – tack free in 60 - 90 minutes; cure time 4-6 hours.

- Surface Preparation & Cleanliness
All surfaces to be coated should be free of dirt, dust, chalking paint, mortar spatter, all loose rust, all loose mill scale, old caulking, grease, oil, release agents, curing compounds, laitance and other foreign matter including frost.
- Coating Application
Mixing
Si-COAT 531AG is supplied as a one-part coating (no component mixing necessary). However, since the coating is a thixotropic gel it is necessary to mix by an air-powered agitator (300 – 400 rpm) for a minimum of 5 minutes, to ensure even consistency of coating is obtained without air in suspension.
Application
All surfaces should be clean and dry before application. The coating should be applied in a manner that prevents runs, sags, drips, spills, etc., and that completely covers surfaces without holidays (gaps). The temperature of the surface to be coated should be between 41 and 140°F (5 and 60°C) and environmental & substrate temperature should be at least 5°F (3°C) above the dew point before and during application.
When working with Si-COAT 531AG in high humidity and/or high-temperature environments, it is recommended to use a pail lid adapter fitted with an agitator. This will prevent the product from skinning over and curing in the pail during application.
It is recommended that Si-COAT 531AG is applied using an Airless Sprayer; however, brush, or roller is also the suitable method of application for small surface areas. It is necessary to apply at a rate that will achieve a minimum of 5 mils (127 μ) DFT. Roller and brush application will require multiple coats to achieve desired DFT.
Graffiti Removal
For best results, graffiti tagging should be removed from the Si-COAT® 531AGTM coating as soon as possible using a cold water pressure washer at 1200 psi. In the instance that graffiti has been left on for a longer period (greater than 10 days) and is stubborn to remove with cold water then a warm water pressure wash may be necessary.
In the extremely rare instance that stubborn graffiti media (specialty paints with adhesion primers that have been left to cure for extended periods) is not removed 100% with warm water then apply a biodegradable surfactant (dish soap) with a cleaning pad and rinse off immediately.
Note: Before applying cleaner to the coating, test a small patch in an inconspicuous area. Contact CSL Silicones Inc. for information and/ or recommendations on which cleaners are most suitable for specific problems.
Thinner
Not recommended.
Equipment Cleaner
CSL901 Equipment Cleaner, Naphtha or Odorless Mineral Spirits.
Work Stoppages & Restarts
Work stoppages are not recommended with only partial utilization of a container of Si-COAT 531AG. If work must stop after only a portion of a container of Si-COAT 531AG is used, seal to minimize air and moisture contact with the coating by covering the surface of the coating with a sheet of polyethylene film, then reseal the container to be airtight.
Upon reopening the container to restart work, peel back the polyethylene film. If curing of the coating has occurred, use a utility knife to cut the cured coating away from the wall of the container. Peel away the cured layer of coating to expose fresh coating underneath.
Clean-up
Do not allow material to remain in hoses, guns or spray equipment. Thoroughly flush all equipment with Si-COAT equipment cleaner, naphtha or mineral spirits.
A fully cured coating is environmentally benign (will not harm) and is suitable for landfill disposal. However, always check local environmental regulations before disposal.
- Systems Compatibility
Although no primer is needed prior to applying Si-COAT 531AG to most common substrates, it is recommended to do a quick field adhesion test prior to application.
