Final answer:
The necessity for using a primer with IKO MVP in a mechanically attached system depends on the manufacturer's guidelines. Primers are often used for adhesion to insulation or cover boards, but may not be necessary in mechanically attached systems unless the manufacturer specifies. Always consult IKO's installation guidelines for accurate instructions.
Step-by-step explanation:
Whether an IKO MVP (Modified Vapour Protector) requires a primer when used in a mechanically attached system depends on the specific application instructions and recommendations provided by IKO for their products. IKO offers various roofing systems and products, each with its installation requirements. It is crucial to follow the manual or technical bulletins provided by the manufacturer for the correct application procedures.
Typically, the need for a primer in a mechanically attached roofing system depends on the substrate and weather conditions. A primer is often needed when the insulation or cover board is to be adhered to the membrane using hot asphalt, cold adhesive, or a self-adhesive membrane. However, in mechanically attached systems, the primary mechanism of attachment is through screws and plates, so a primer may not be required unless specified for enhancing the bond at specific points or with particular products.
It is always best to consult the IKO installation guidelines for the most accurate and up-to-date information regarding the need for a primer with their MVP product in mechanically attached systems. Failure to adhere to these guidelines could result in a compromised roofing system and potentially void the warranty.
