Surface Preparation
All surfaces to be sealed or bonded must be dry, sound and free from dust, crumbling parts, oil, grease, wax and old paint. When used for sealing Mapeflex PU45 must only bond perfectly to the sides, not the bottom, see technical data sheet to prevent this. Mapeflex PU45 withstands movement when in servive of up to 20% of the average width of the sealed joint. Use masking tape along the edges of the joint to provide an attractive finish. This must be removed immediately after smoothing the sealant.

Recommended Systems
When used as a sealant - Place a cartridge in the special extrusion gun, make a hole in the tip of the cartridge, screw on the extrusion nozzle, cut the nozzle at a 45° angle dependent on the width required. Squeeze out the product in a continuous flow into the joint, avoid trapping air. Immediately after extruding the product, smooth over the surface with suitable sized and shaped tool while keeping it continuously wet with soap and water. When used as a flexible adhesive - When bonding sections with a restricted surface area, extrude single drops of the product on the back of the section and press it down well on to the substrate to spread the adhesive uniformly. When bonding sections with a large surface area, extract a series of vertical, parallel beads approx. 150mm apart and press on well to spread the adhesive uniformly. If required, the bonded element may be adjusted within 30 minutes of application at a temperature of +23°C. When bonding heavy loads or in critical conditions, extra support such as clamps or props may be necessary for the first 24 hours at +23°C. Do not bond with layers of product more than 3mm thick.
