How to use a internal builder’s profile

Step 1 – Cut out two joints

Cut out two vertical joints in the mortar on the second course inside the corner.

Step 2 – Attach setting device

Use the setting device to hold the profile in place. The attachment should be placed with the curved end facing down and towards the bricks.

Step 3 – Slacken adjusting screws

As with the external profile, the upper setting screws on the fins are pre-set and do not need adjusting.

Slacken the lower adjusting screws to leave the profile leaning slightly away from the corner; this will help you make the profile plumb later on.

Step 4 – Attach clamps brackets to bolts

Slide the clamp brackets onto the bolts, (important: the longer end must go on first). Use a wing nut to secure this in place and then hook the bolts onto the profile fins.

To fully secure the profile in place, push the ends of the clamp bracket into the mortar joints created in step 1. Now the setting device can be removed.

Step 5 – Make plumb

Use a spirit level on both sides of the profile, tightening the bottom setting screws until the profile is plumb.

Step 6 – Attach line holder

Place the line holders onto the profile, this time with the closed side facing the wall.

Step 7 – Use stabilisers

As with the external profile, stabilisers need to be used every five courses to stabilise the profile under tension.

Adjust the stabiliser screws so they form a right angle and slide onto the profile with the screws facing the wall.
