In floor soundproofing projects a soundproof primer is used to condition and prepare a flooring substrate for the application of a composite underlayment like PROFLEX™ 90 , and to ensure there’s a tight bond between the subfloor and the added underlayment. Soundproof Cow carries PR 11 brand flooring primer, a 100% water-based soundproof primer that can be applied to wood or concrete with a paint roller. PR 11 soundproofing primer is non-flammable and can be used on both interior and exterior projects, but should not be applied if rain is imminent.

How to Install

Our soundproof primers are simple to install both indoors and outdoors, no matter the level of moisture or rain the surface of application will be exposed to in the future. However, during the application process, make sure the surface is dry and clean to ensure the proper bonding of materials.

Install PROFLEX™ 90 by rolling out and peeling the material in measured proportions and aligning the Proflex 90 to the desired location. Use a heavy roller when bonding the material to the floor to ensure correct adhesion. To install PR 11 primer, simply apply the well-mixed components with a roller or brush to your floor, allowing it to dry for 15 to 45 minutes.

Cautions and Limitations

Take precautionary action when handling this product to avoid contact with skin or eyes. Application areas should be dry, and the installation process may take longer under colder conditions. When not in use, soundproof primers should be covered fully and stored in room temperature climates averaging between 50-100ºF.

When using PROFLEX™ primer, first consult with a manufacturer to ensure the proper compatibility. Proflex 90 primer should not be used on floors where hydrostatic pressure is present, over expansion joins or structural movement cracks. Do not mix Proflex 90 primer with any additional products, either. During the application process and shortly thereafter, remember to keep your primer away from children and dispose of remaining residue in an environmentally-safe manner.

Compatible Products

PR 11 is compatible in use with PROFLEX™ 90. Proflex primer should not be thinned nor mixed with any additional products. Because Proxflex 90 consists of bond forming membranes that adhere to steel, concrete and wood substrates, Proflex 90 is also compatible with most urethane, epoxy and cement adhesives. Get in touch with us today for more information on this product as well as our other soundproofing materials.

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.
