How to use a builder’s profile with
stay bars?

Step 1 – Position profile

Position your profile in the corner of your foundation and nail it in place.

Place a brick at the bottom of the profile without mortar to check it is positioned at a 90° angle.

Step 2 – Attach stay bars

Attach the two stay bars either side of the profile, screwing them onto the profile with screws provided, to about a 30° angle. Then nail them into your foundations with the back edge of the stay bar in line with the back edge of the profile.

Step 3 – Make horizontal

Some profiles come with gauge notches already on them, normally at 75mm (2.9″) intervals. If not, mark out your own gauge points and set each line holder at the same point to make the profiles horizontally level.

Step 4 – Make plumb

Next, the profile needs to be made vertically level (plumb). Use a spirit level to ensure this, adjusting the profile by turning the sleeves on the stay bars clockwise. The sleeves have nuts either side which are turned clockwise to lock them in place.

Step 5 – Attach string line

The profile is now ready to be used.

Attach the string line to the line holders at the first notch or gauge mark and pull it tight between the two profiles.

Step 6 – Lay mortar

Place the first layer of mortar down onto the foundations and run the bricks along the string line. Move the string line up the next notch once the first course is complete. It is still important to check with a spirit level every couple of courses that you are building level and plumb.
