The market offers several water-based acrylic dispersion adhesives so it is important for contractors to ensure that they select the adhesive best suited to the project’s specifications and substrate.
FloorworX’ rigid quality control has earned them the reputation for offering flooring adhesives with consistent high quality and multi-purpose use. Their FloorworX No.62 water-based acrylic dispersion adhesive was specially developed for use in bonding resilient vinyl flooring and LVP products to cement screeds and carries a non-flammable and non-toxic classification.
Commenting on how to ensure professional installation, Roy Sinclair from FloorworX says, “Subfloor preparation is an essential precursor to ensuring successful adhesion and a long-wearing finish.”
FloorworX’ essential preparation steps:
Ensure that the subfloor is:
• Smooth, hard, mechanically strong and without cracks.
• Clean – free of all paint spots, wax, rust, grease, patches of oil or any other foreign matter.
• Tested for dryness using a suitable Concrete Moisture Meter.
• Protected from rising moisture using an effective damp-proof membrane.
• Primed in case of excessively porous or dusty surfaces by using a suitably recommended primer before the application of adhesives.
• Sound and compliant to a Grade-1 floor finish as set out in SANS 10070 Code of Practice: The installation of resilient thermoplastic and similar flexible floor covering materials, in terms of levelness.
In terms of application, refer to the FloorworX application instructions on the product packaging. FloorworX also recommends the following precautionary tips to avoid installation issues or problem areas.
Top Precautionary tips
- Do not use FloorworX No. 62 adhesive when the subfloor temperature is below 6ºC.
- Stir the adhesive well before use.
- Do not use FloorworX No. 62 adhesive on woodblock flooring.
- Do not spread large areas of adhesive.
- Do not lay into the adhesive too early or too late.
- Adhesives should be stored indoors on a wooden pallet at a temperature of not less than 6° to prevent freezing.
- FloorworX No. 62 adhesive has a shelf life of approximately 12 months, but stock rotation is recommended as a matter of course.
- If the trowel notching is too large, an excessive amount of adhesive will be applied to the subfloor resulting in adhesive weeping through the joins. Allow 24 hours or longer before welding sheet flooring material.
- Do not use solvent-based cleaners to remove adhesive from the floor surface. Any excess adhesive should be removed immediately using a clean, damp rag, warm water and a detergent.
