Takeaways

• 😀 Bonas 540 is a versatile moisture barrier primer that works over plywood, OSB, Advantech, gypsum, and concrete.
• 😀 This product is not suitable for use on plastic surfaces due to its silane composition, which doesn’t adhere to plastics.
• 😀 The 540 primer provides 20% moisture protection over plywood with a single coat and up to 18 pounds moisture protection over concrete with two coats.
• 😀 Over plywood, only one coat of 540 is needed, while two coats are required for concrete to ensure proper moisture protection.
• 😀 The primer helps to reduce the moisture content of wood and concrete, making it safer to install flooring in high-humidity environments.
• 😀 540 primer works as a vapor retarder, slowing the transmission of moisture and preventing wood curling or warping.
• 😀 Application of 540 primer is easy, using a 3/16” or 1/4” mohair roller to apply a tight, even coat over surfaces.
• 😀 The primer is dry to the touch in 2–2.5 hours when applied to plywood and requires 16 hours for drying before full glue application over concrete.
• 😀 There is no odor to the 540 primer or 850 adhesive, and they are GREENGUARD certified for low emissions.
• 😀 The 540 primer can be used as a base for glue assists, offering both moisture protection and adhesive bonding without the need for an additional vapor barrier.
• 😀 The 540 primer simplifies the installation process by eliminating the need for traditional paper-based moisture barriers, saving time and reducing installation complexity.
