Strait-Flex Gold is a mud-on, paper-faced composite corner bead that adjusts to any angle to create perfect inside and outside 90° and off-angle corners.

The composite structural backing 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. Strait-Flex Gold is packaged in 100 ft. rolls that can be cut to the desired length in the field to minimize scrap loss.

  • Memory-free hinge produces straight corners and perfect angles
  • Smooth nose provides a square, low profile
  • Composite-fiber structural 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
  • Installs with all-purpose joint compound


  • Inside and outside 90° and off-angle corners
  • Inside and outside corners where common gaps in drywall are present
  • Inside 90° corners where a large fill or straightening is required, no back filling needed
  • Great for vaulted, coffered and tray ceilings, bay windows

Make sure the surfaces of the corner are clean and smooth. Measure corner and subtract 1/2”. (1) For accurate measuring of Strait-Flex® Gold and less waste, feed roll through slot on top of box. Hook tape measure on the hole below. (2) Fold Gold in half with the print side facing out. (3) For outside corners, fold more than the desired angle. For inside corners, fold less than desired angle. (4) Most professionals prefer to cut the ends of Gold at a 45º angle.

(5)  Apply a liberal coat of all-purpose joint compound to both sides of the corner with a 4” or 5” taping knife.  (6) Press Gold into the wet compound. Adjust, if necessary, to create a straight line. (7) Wipe down tight with taping knife using a little additional pressure on the outer edges. Let dry completely over several hours or overnight.

(8) Apply a light skim coat of compound to the outer edges of Gold with a 4” or 5” taping knife. No compound is required over the laminated area of Gold. Wipe down tight and smooth. Let dry completely over several hours or overnight.

(9) 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.

(10) Sand lightly with 120 grit sandpaper. Gold will not fuzz-up like paper or mesh tapes.


Asegúrese de que las superficies de la esquina estén limpias y lisas. Mida la esquina y reste 1/2". (1) Para medir el Strait-Flex® Gold 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. (2) Doble el Gold por la mitad con la cara impresa hacia fuera. (3) Para esquinas externas, doble a un ángulo mayor al deseado. Para esquinas internas, doble a un ángulo menor al deseado. (4) La mayoría de los profesionales prefieren cortar los extremos del Gold a un ángulo de 45º.

(5) Aplique una capa generosa del compuesto multiusos para juntas en ambos lados de la esquina con una espátula de 4" o 5".  (6) Presione el Gold sobre el compuesto húmedo. Si es necesario, ajuste para crear una línea recta. (7) 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.   

(8) Aplique una capa ligera del compuesto a los bordes exteriores del Gold con una espátula de 4" o 5". No necesita aplicar compuesto sobre las áreas laminadas del Gold. Raspe para que quede lisa y al ras. Permita que se seque completamente, por varias horas o durante la noche.   

(9) 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.

(10) Lije ligeramente con papel de lija grano 120. Gold no hace pelusa como sucede con las cintas de papel o malla.
