Most profiles require three courses of the wall to have already been built before they can be used. This is so that there is enough room for the two fins to be attached to the wall.The three course base will need to be left to set overnight before the profile can be attached. To find out how to do this, see: . | |||
 |
It is essential that you make sure the first three courses of your wall are correct. They need to be completely plumb, level and square to make sure the profile is accurate later on. Use a spirit level to check each brick when building up your first three courses, especially around the corner. | |||
 |
Each profile is set up differently depending on which type it is. To find out how to set up a profile, see our section:
Once the profile has been built, you can set up the string line and continue building your wall. |

 |
Some builder’s profiles already have gauge marks set on the profile post, normally at 75mm (2.9″) intervals. Gauge marks are measurements used as a reference point during building. The marks/measurements will vary depending on the size of the bricks or blocks you are using. | |||
 |
If your profile does not have markings or you wish to make extra markings, use a ruler measuring from the top of the profile plate. Most profiles recommend you use masking tape to make your markings so that the profile is easily reused. | |||
Setting up the line |
||||
 |
Step 1 – Place line holdersFirst, to set up the line, place the plastic line holders onto your profile by positioning them over the top and down the pole until you reach your first gauge mark (this will probably be 75mm (2.9″) above your last built course if you are using standard 65mm (2.5″) bricks). |
|||
 |
Step 2 – Attach masonry stringGet your masonry string and hook around the first line holder. It is attached to the line holder on both sides around the line holder’s hooked edges. Gently tug the line to make sure it does not loosen and that it is fully secure. |
|||
 |
||||
 |
Step 3 – Attach string linePull the string line along to your other profile, making sure it is pulled completely tight and there is no room for slack. Make sure the string line is at the correct level and distance to your brick course. Do not have the string line touching the wall as this will cause it to loosen and become inaccurate. |

Using the stabilisers |
||||
 |
The stabilisers should be used after every five courses, moving up as you progress. This is to stabilise the profile under tension. | |||
|
Adjust the screws so that they form a right angle. This will sit around the corner and prevent the profile from pulling over. | |||
