Remove dirt, oil, grease, old sealants, poorly bonded coatings, dust and loose material.\u003c\/li\u003e\n\u003cli\u003eFor optimum adhesion and critical applications, follow Sika's pretreatment instructions. Lightly abrade aluminium, anodised aluminium, stainless steel, galvanised steel, powder-coated metals and glazed tiles, then clean and treat with Sika Aktivator-205. Wait more than 15 minutes but less than 6 hours before sealing.\u003c\/li\u003e\n\u003cli\u003eFor brass and titanium-zinc, apply Aktivator-205, wait more than 15 minutes but less than 6 hours, then apply Primer-3 N. Wait more than 30 minutes but less than 8 hours before sealing. For PVC, use Primer-215 and wait more than 30 minutes but less than 8 hours. Clean glass with isopropanol.\u003c\/li\u003e\n\u003cli\u003eWhere a porous substrate is approved for the application, use Primer-3 N and wait more than 30 minutes but less than 8 hours. Primers do not replace proper cleaning or make an unsuitable substrate suitable. Perform project-specific adhesion tests before full application.\u003c\/li\u003e\n\u003cli\u003ePrepare suitable joint backing, load the cartridge into a compatible sealant gun and apply evenly with full contact against the joint sides.
