APPLICATION
Ease of Installation
•Single component high solids formula
•Easily gunnable between 40o F and 100o F (4.4o C and 37.8o C)
•Cures rapidly to reach optimum strength within 7-14 days, fully cured within 21 days
•GreenWeld A/S can be installed on damp surfaces which are defined as when no moisture is transferred to the skin when the substrate is touched.
Viking Products Group highly recommends that coated substrates be tested for proper adhesion prior to starting a project to determine suitability for use.
Standard: Remove all dirt, oil, loose paint, frost and other contamination from all working surfaces. Maintain GreenWeld A/S 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 fifteen minutes of application.
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.
Wood: Wood should be clean, sound and dry prior to application. Allow treated wood to weather for six months prior to application. Remove all coatings and paint to ensure proper adhesion. GreenWeld A/S is not recommended for use on fire retardant lumber.
Priming: In most applications GreenWeld A/S 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.
Concrete: Prior to application remove any residual contamination by mechanical abrasion, sand blasting or power washing. On green concrete, remove all release agents, friable and loose concrete. Dry all visible and standing water prior to applying GreenWeld A/S.
