Finishes inside 90° and off-angle corners
Pro-Flex300 is a muddable, PVC-Free, flexible corner bead that adjusts to any angle to create perfect inside and outside 90° and off-angle corners.
Application(s): Drywall
Pro-Flex300 features a reinforced paper backing which provides strength for durability and impact resistance. The heavy-weight, diamond punched paper provides maximum adhesion for an even lay-down of the paper edge and reduced edge cracking. Pro-Flex300 is packaged in 100 ft. rolls that can be cut to the desired length in the field to minimize scrap loss.
- PVC-Free, the superior choice for green building projects.
- Memory-free hinge produces straight corners and perfect angles
- Smooth nose provides a square, low profile – drywall knives will not catch, snag or puncture center hinge
- Reinforced paper backing provides strength and embeds into compound to provide a superior bond to the drywall surface
- Diamond-punched paper edging provides maximum adhesion – no cracks, no call backs
- Paper surface is pretreated to accept paint, finishing compound is not required over the laminated area – uses the half the compound vs. standard corner bead
- Paper will not fuzz-up during finish sanding like paper and mesh tapes
- Installs with all-purpose joint compound. No special tools or fasteners are needed. Lightweight compound may be used to finish.
Applications:
- Great for vaulted, coffered and tray ceilings, bay windows.
- Outside corners where common gaps in drywall are present.
- Outside corners where a large fill or straightening is required, no back filling needed.

Installation
Make sure the surfaces of the corner are clean and smooth. Measure corner and subtract 1/2”.
- For accurate measuring of Pro-Flex300 and less waste, feed roll through slot on top of box. Hook tape measure on the hole below.
- Fold Pro-Flex300 in half with the print side facing out.
- For outside corners, fold more than the desired angle. For inside corners, fold less than desired angle.
- Most professionals prefer to cut the ends of Pro-Flex300 at a 45º angle.
- Apply a liberal coat of all-purpose joint compound to both sides of the corner with a 4” or 5” taping knife.
- Press Pro-Flex300 into the wet compound. Adjust, if necessary, to create a straight line.
- Wipe down tight with taping knife using a little additional pressure on the outer edges. Let dry completely over several hours or overnight.
- Apply a light skim coat of compound to the outer edges of Pro-Flex300 with a 4” or 5” taping knife. No compound is required over the laminated area of Pro-Flex300. Wipe down tight and smooth. Let dry completely over several hours or overnight.
- Apply the final coat of joint compound with a 6” or 8” taping knife. Feather the compound beyond previous coat. A very light coat of compound is all that’s needed. Using lightweight compound in this step makes sanding easier. Let dry completely over several hours or overnight.
- Sand lightly with 120 grit sandpaper. Pro-Flex300 will not fuzz-up like paper or mesh tapes.
INSTRUCCIONES DE INSTALACIÓN
Asegúrese de que las superficies de la esquina estén limpias y lisas. Mida la esquina y reste 1/2".
- Para medir el Pro-Flex300 con más precisión y menos desperdicio, inserte la cinta a través de la ranura en la parte superior de la caja. Enganche la cinta métrica en el agujero que está debajo.
- Doble el Pro-Flex300 por la mitad con la cara impresa hacia fuera.
- Para esquinas externas, doble a un ángulo mayor al deseado. Para esquinas internas, doble a un ángulo menor al deseado.
- La mayoría de los profesionales prefieren cortar los extremos del Pro-Flex300 a un ángulo de 45º.
- Aplique una capa generosa del compuesto multiusos para juntas en ambos lados de la esquina con una espátula de 4" o 5".
- Presione el Pro-Flex300 sobre el compuesto húmedo. Si es necesario, ajuste para crear una línea recta.
- Raspe con la espátula para que quede al ras, usando un poco más de presión sobre los bordes externos. Permita que se seque completamente, por varias horas o durante la noche.
- Aplique una capa ligera del compuesto a los bordes exteriores del Pro-Flex300 con una espátula de 4" o 5". No necesita aplicar compuesto sobre las áreas laminadas del Pro-Flex300. Raspe para que quede lisa y al ras. Permita que se seque completamente, por varias horas o durante la noche.
- Aplique la capa final del compuesto para juntas con una espátula de 6" o 8". Raspe el compuesto hasta cubrir completamente la capa anterior. Una capa muy ligera del compuesto es todo lo que necesita. Usar un compuesto más ligero en este paso, hace que sea más fácil de lijar. Permita que se seque completamente, por varias horas o durante la noche.
- Lije ligeramente con papel de lija grano 120. Pro-Flex300 no hace pelusa como sucede con las cintas de papel o malla.
