Frequently Asked Questions

1

What surfaces is ARBO® Primer 925 designed for?
ARBO® Primer 925 is designed for priming asphalt and bituminous surfaces to improve adhesion of various ARBO® sealants. It is a solvent-based, air-drying isocyanate resin primer. Please consult ARBO® Technical Services for advice on specific applications.

2

What is the minimum joint width when using ARBO® Primer 925?
The joint width should be at least 6mm in order that the joint faces can be cleaned and primed correctly. Apply one coat using a clean dry brush and allow to dry for at least 1 hour but not more than 8 hours before applying the sealant.

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.
