R-Mer Coat PVDF Primer is a water-based primer specifically formulated with the R-Mer Coat topcoat. R-Mer Coat PVDF Primer allows the system to adhere to Kynar 500® PVDF finishes or substrates previously painted with a PVDF-based finish. R-Mer Coat PVDF Primer not only enhances the adhesion of the R-Mer Coat paint system, it also saves building owners money by allowing R-Mer Coat to be applied more efficiently and with less material. Combined with the R-Mer Coat topcoat, R-Mer Coat PVDF Primer completes one of today's highest-performing coating systems.

Spray | Ambient air temperature is important to the coatings performance and how the film cures. Be sure to check that the air and material temperature are between 50°-90°F (10o-32.2oC) and at least 5°F (-15oC) above the dew point. Do not apply if rain is expected within 24 hours or if the air or surface temperature is expected to drop below 50°F (10oC) for 24 hours after application. Do not apply the coatings in direct sunlight as the flow and cure time can directly be affected. R-Mer Coat PVDF Primer must be applied with approved spray equipment – the Graco GMAXII 7900 or an equivalent pump. The airless spray pump must have a minimum 2,000 psi output pressure rating as well as adequate del ivery volume to support the spray tip orifice gallons per minute rating. Proper pressure will vary by job, hose length, tube size and width of substrate. Please consult the Garland R-Mer Coat spray guide for complete detai ls. After preparing the substrate, before beginning to spray, mix R-Mer Coat PVDF Primer. Spray R-Mer Coat PVDF Primer at a coverage rate of 3-4 wet mils or 400-450 sq.ft./gal. (9.8-11.05 m2 /l). Once the primer has dried, check the adhesion of the primer to the substrate using ASTM D3359 tape test before applying the topcoat. R-Mer Coat PVDF Primer will dry to the touch in 30-60 minutes at 77°F (25oC), 50% humidity. Wait for primer to fully cure for 24 hours before applying topcoat. |

Application Guidelines | R-Mer Coat Metal Coating System Spray Application Guidelines |
R-Mer Coat PVDF Primer’s unique chemistry adheres tenaciously to PVDF-coated metal surfaces, so there are no concerns of failed bonding or peeling on the substrate. The R-Mer Coat PVDF Primer complements the R-Mer Coat topcoat, completing the secure system bond for long-term performance.
With a low VOC content, this water-based product is very environmentally friendly.
In the event of overspray, R-Mer Coat PVDF Primer can be cleaned off surfaces with warm, soapy water before it dries instead of harsh solvents or cleaning agents.
