Frequently Asked Questions

1

Which sealants is ARBO® Primer 2650 compatible with?
ARBO® Primer 2650 is developed specifically for use with the Arbosil Silicone range, the Arbomeric MP range, and the ARBO® EPDM Membrane System. It is designed to prime porous surfaces such as concrete, blockwork and brickwork prior to sealant application.

2

How is ARBO® Primer 2650 applied?
Apply one coat of ARBO® 2650 Primer using a clean dry brush to clean, dry, degreased joint surfaces. Allow to dry for at least 1 hour but not more than 8 hours before applying the sealant. Consult ARBO® Technical Services for advice in specific instances.

3

What types of surface preparation products does ARBO® offer?
ARBO® offers a comprehensive range of ancillary products to support professional joint sealing and surface preparation. This includes primers (AG2 Porous Primer, ARBO® Primer 2650, ARBO® Primer 925), a full range of cleaners and degreasers (ARBO Cleaner 16, ARBO Cleaner 17, ARBO Glass Cleaner, ARBO® PVC Solvent Cleaner), and specialist products such as CARLISLE® Foam Cleaner for equipment maintenance.
 
 

4

Why is surface preparation important before applying an ARBO® sealant?
Proper surface preparation is critical to achieving the specified performance of any ARBO® sealant. Joint faces must be clean, dry and free from all contamination. Failure to degrease and prime correctly can result in adhesion failure. ARBO® Cleaners remove oils and residues; ARBO® Primers promote adhesion on porous substrates. All joint preparation should be carried out in accordance with BS 8000-16: 1997 + A1: 2010.
 

5

How do I select the correct ARBO® Cleaner for my substrate?
ARBO Cleaner 16 (alcohol-based) is recommended for sensitive surfaces including PVCu, EPDM, glass, painted surfaces, and powder-coated substrates. ARBO Cleaner 17 (Xylene-based) is suited to harder substrates including aluminium, steel, copper, GRP, untreated timber, and concrete. ARBO Glass Cleaner is formulated specifically for glass and impervious reflective surfaces. ARBO PVC Solvent Cleaner is designed for solvent cleaning of PVC window frames and doors. If in doubt, consult ARBO Technical Services.
