- Product Application
Application
Surfaces must be clean, and free from dust, dirt, and grease. Maintain SB 500 at room temperature before applying to ensure easy gunning and tooling. Test and evaluate to ensure adequate adhesion. Carefully gun the sealant with a smooth, continuous bead. If tooling is needed, do so within ten minutes of application.
Concrete
Prior to application remove any residual contamination by mechanical abrasion, sand blasting or power washing. On green concrete, remove all release agents and loose concrete. Dry all visible and/or standing water. Install an appropriate backer rod to avoid three-point bonding.
Metal
Prepare all metal to ensure maximum adhesion. Remove all rust, scale and residue using a wire brush. Remove films, loose or inappropriate coatings and oils with an appropriate solvent such as alcohol. Seal Bond recommends that coated substrates be tested for proper adhesion prior to starting a project to determine suitability for use.
Wood
Wood should be clean, sound and dry prior to sealant application. Allow treated wood to weather for six months prior to application. Remove all coatings and paint to ensure proper adhesion. SB 500 is not recommended for use on fire retardant lumber.
Priming
In most applications SB 500 will not require a primer. However, certain substrates may require a primer to ensure a long lasting bond and weatherproof seal. It is the applicator’s responsibility to determine whether or not a primer is needed in their specific application.
Clean-up
Clean tools with an appropriate solvent such as alcohol. Avoid using water for cleanup.
