Description
The Procat aluminium straightedge, also known as a screed board, is designed for demanding measuring and levelling work on construction sites. The body of the tool is made of light but durable aluminium, which makes it easy to handle even in long lengths. The key feature of the straightedge is the support frame built inside its profile. This structure stiffens the straightedge and stops it from twisting or bending in use, ensuring a straight line and an accurate result in levelling work.
Straightedges are widely used for checking that surfaces are straight and for spreading compounds. They are an essential tool especially for levelling floor screeds and levelling compounds, where a long straightedge can true large surfaces efficiently in one go. They are also suitable for checking the levels of structures such as frame battens, and they work as sturdy saw guides when cutting building boards, for example.
Procat aluminium straightedges are available in several lengths, with different profiles (including bevelled edges) and handle options depending on the intended use. All models have removable end caps. This lets you shorten the straightedge by sawing if site conditions call for a custom length.
Intended use:
The Procat aluminium straightedge is a versatile tool designed primarily for ensuring straightness and levelling materials.
- Levelling floor screeds: Used to spread wet floor compounds such as concrete or levelling compounds and to true the surface to the required level.
- Checking surface straightness: Visual or measured checking of the flatness and straightness of walls, floors and other structures.
- Checking frame structures: For example, checking the alignment and levels of wall or ceiling battens before boarding.
- Saw guide: Works as a long, straight guide rail for a circular saw or other saws when cutting building boards.
Package contents:
- 1 pcs Procat aluminium straightedge (selected length and model).
Features:
The technical features of the straightedge are designed to guarantee durability and accuracy in construction use.
- Aluminium construction: The material is light, which makes handling easier, but durable enough for site use.
- Internal support frame: The reinforcing structure inside the profile stops the straightedge from twisting and keeps it straight.
- Removable end caps: The plastic end caps can be removed, so the straightedge can be shortened to a suitable length by sawing.
- Versatility: Suitable for spreading compounds as well as for accurate measuring work.
- Variations: Available in different lengths and profile models (e.g. bevelled edges) for different work stages.
Technical specifications:
- Material: Aluminium.
- Construction: Hollow profile with internal support frame.
- Ends: Removable plastic caps.
Instructions for use:
Levelling work: When you use the straightedge to true a floor screed or levelling compound, draw it over the surface of the compound, using it as a “screed” running on the guides or level points. Move the straightedge back and forth sideways while pulling it towards you, so the compound levels out and the excess material is removed.
Checking: Place the straightedge against the surface to be checked. Look at the gap between the edge of the straightedge and the surface. If light shows through or the straightedge rocks, the surface is not straight.
Shortening: If the straightedge needs shortening, first remove the end cap. Saw the aluminium profile to the length you want with a hacksaw and file the cut smooth. Put the end cap back in place.
Maintenance: Clean the straightedge immediately after use, especially if it has been used with cement-based products. Dried compound can affect the straightness and usability of the straightedge.
Warnings:
- Damage: Do not use a twisted or dented straightedge for measurements that need accuracy, as it will not give a reliable result.
- Electrical conductivity: Aluminium conducts electricity. Take care not to touch live electrical cables when working with the straightedge.
- Impacts: Avoid hard impacts on the straightedge, as they can permanently damage the aluminium profile.
Frequently asked questions (FAQ):
Can an aluminium straightedge be cut?
Yes, it can. Procat straightedges have removable end caps, so the profile can be sawn to the length you want with a hacksaw.
Will the straightedge definitely stay straight?
The support frame built into the straightedge is designed to prevent twisting in normal use. However, hard impacts, incorrect storage (e.g. under heavy objects) or dropping can damage the profile and affect its straightness.
What length of straightedge should I choose?
The length depends on the intended use. Long straightedges (over 2m) are best for levelling large floor areas and checking long lines. Shorter models suit tighter spaces and smaller levelling jobs.
Recycling instructions:
The product is made mainly of aluminium, which is a fully recyclable material. At the end of its service life, take the aluminium profile to metal recycling. Sort the removable plastic end caps into plastic collection or energy waste according to local instructions.
