Bostik Seal ‘N’ Flex FC can be painted as early as 24 hours after application using water borne coating and most epoxy coating systems. Coatings containing high solvent contents such as gloss enamels or high oil based undercoats may cause the surface of the sealant to react creating a tacky surface to develop. A field test is recommended to ensure compatibility. To obtain best appearance and performance the paint must approximate the elongation capabilities of the sealants. High build coatings with some elastomeric ability such as quality acrylic emulsions have the capability to absorb low movement without significant distortion of the paint film.

1. Bostik Seal ‘N’ Flex FC when used as an adhesive or sealant should be dispended from either the cartridge or sausage sachet by means of a hand or air operated caulking gun designed for such application (available from Bostik).
2. Pierce the membrane from the top of the cartridge and screw on the supplied nozzle. Having previously cut this to give the required angle and bead size.
3. Place the cartridge in a suitable Bostik extrusion gun and press the trigger. For sausages, a barrel gun is required and this is available from Bostik. Clip the end of the sausage and place complete sausage with pierced end located at the top of the nozzle. Screw top of nozzle and housing on barrel of gun. Using the trigger on the gun extrude product from the sausage to stop product flow, using the thumb, depress the catch plate mechanism located at the very rear of the gun, directly above the trigger.
4. Apply Bostik Seal ‘N’ Flex FC in a continuous operation using positive pressure adequate to properly fill and seal a cavity.

Bostik Seal ‘N’ Flex FC does not need to be applied to both surfaces to bond, but both surfaces must be prepared in accordance with preparatory work.

Apply in beads or daubs to the prepared substrate. Materials being adhered can be bonded immediately or left open for up to 15 minutes after application prior to bonding. If no mechanical fixing is to be used in conjunction with adhesive, clamping is necessary untill full care is achieved.

Use only enough sealant to achieve adequate bond (dependant on surface texture). Excess sealant can be removed by dry cloth or solvent wipe before curing.

If adhesive is to be exposed, smooth off with spatula or putty knife to flush finish
