stay bars

Wall built with stay bar profiles Profiles with stay bars can only be used in projects where a hard surface or foundation has been set first. This is so the stay bars and profile can be nailed in the foundation and remain steady. If you were to try and secure them on soil ground the profile would never be completely plumb or level.
Step 1; nailing the profile into the foundations

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; attaching stay bars to profile and nailing into foundations

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; making the profile level horizontally

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.

   Wonkee Donkee says; Gauge marks are measurements used as a reference point during building, the marks/ measurements will vary depending on the size bricks or blocks you are using.
step 4 adjust the stay bars by turning the sleeves on the stay bars

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; set up the string line between the two profiles

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 the mortar and build first using using first notch on slider

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.
