Products : Flooring Installation Systems : Priming : CP-A Acrylic Primer
This product has been discontinued. Please reference our CustomTech line of products.
CP-A is an advanced acrylic primer and sealer that prepares surfaces for the application of an appropriate Custom® self-leveling underlayment. It seals porous and non-porous surfaces and improves the bond of the underlayment to the subsurface.
Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.
Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product may contribute to LEED® certification.
Surfaces must be structurally sound, clean, dry and free from grease, oil, dirt, curing compounds, sealers, adhesives or any other contaminant that would prevent a good bond. Refer to the appropriate Custom® self-leveling underlayment technical data sheet for details on bonding to specific substrates.
Contains acrylic emulsion. Wear suitable gloves and eye protection. Avoid eye contact and prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, flush with water for 15 minutes and consult a physician. If skin contact occurs, wash immediately with soap and water. Dried material is extremely difficult to remove. KEEP OUT OF REACH OF CHILDREN. DO NOT TAKE INTERNALLY.
Stir and use undiluted for non-porous surfaces.
Dilute up to 3 parts water to 1 part primer with clean, potable water for highly porous concrete surfaces. Highly absorptive substrates may require a second application of diluted primer. Diluted primer must be used within 24 hours of mixing.
Undiluted: Since settling may occur, stir using a low speed (300 rpm) power mixer; do not over-mix.
Diluted: Before dilution with water, stir with a low-rpm mixer for approximately 1 minute to re-suspend any settled material. Mix for 1 minute with dilution water using a low speed (300 rpm) mixer with a low-intensity mixing blade.
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.
Apply with a push broom. Apply a thin, even coat; do not allow puddling. Allow to dry to a clear film (1 to 3 hours, depending on ambient conditions and dilution) before applying an appropriate Custom® self-leveling underlayment. Highly porous concrete surfaces (indicated by rapid drying or absorption of the primer on the substrate) may require a second coat of diluted primer. Areas must be reprimed if primer is allowed to dry more than 72 hours, or if excessive dust debris or other contaminants have been worked into the primer surface.
Use 1/4" nap roller for the application of primer over moisture vapor control membrane, exterior plywood, VCT, OSB and other non-absorbent substrates which require the use of undiluted primer.
Clean with water before the material dries.
Store in a cool, dry area. Keep from freezing.
Store in a cool, dry area. Keep from freezing; product is not freeze-thaw stable.
