Acclimation and site conditions
Bona R880 is best applied between 10ºC and 26ºC.
Substrate preparation
Substrate must be clean, smooth, dry, free of loose material and structurally sound, with the surface slightly textured for best adhesion. Remove adhesive residue, paint, concrete curing compounds or other contaminants that may affect adhesive bond. If applicable, substrates must meet the requirements of local codes and practices.
Product limitations
On vertical surfaces, the use of mechanical fasteners may be necessary to facilitate adhesive capabilities until the final cure strength is achieved. Bona R880 is not to be used as a structural / load bearing adhesive. For interior use only.
Application
Bona R880 needs to be applied using a standard 10 oz. caulking applicator.
- Cut end of tube above threads to expose adhesive.
- Attach supplied applicator tip to threaded end of R880 tube.
- Remove threaded cap and cut applicator tip to desired bead size.
- Apply sufficient material to the surface or surfaces being bonded. Open time for R880 is 10 minutes. NOTE: For heavier applications, especially on vertical surfaces, the use of mechanical fasteners or temporary support may be necessary until bonding strength is achieved. If additional bond strength is needed, lightly misting the substrate surface or the applied adhesive with water will accelerate the initial bonding strength. The addition of water will decrease the open time to 5 minutes.
- Position material to substrate as desired.
- Save any remaining materials by attaching provided cap. NOTE: If R880 tube is to be sealed for later use, be sure to cut the applicator tip beyond the cap threads.
