Blue Spot Tools Hi-Vis Braided Nylon String Brick Line

MPN: 34650

Barcode: 5028734346503

Size: 100m (328ft)

Weight: 0.11kg

Colour: Hi-Vis Yellow

Overview:

The Blue Spot Tools Hi-Vis Brick Line gives you a clear, taut reference point for every course you lay. It comes on a compact reel with 100m (328ft) of bright, high-visibility braided nylon string. Built-in elasticity keeps the line under consistent tension during use.

The braided construction holds its shape and resists sagging between anchor points. The line resists abrasion from rough masonry surfaces and stands up to alkali attack from mortar and cement. These properties extend the working life of the line on-site.

Key Features and Benefits

• High-Visibility Colour: The bright string stays easy to spot across a work area, reducing errors when sighting along a course.
• Built-In Elasticity: The line snaps back under tension, keeping your course guide taut without constant re-adjustment.
• Braided Nylon Construction: A tight braid resists sagging and unravelling, giving a straighter reference between anchor points.
• Abrasion Resistant: Contact with brick faces, blocks, and trowel edges will not easily damage the string.
• Alkali Resistant: The line withstands direct exposure to mortar and cement without degrading.
• 100m Length: One reel handles most residential and larger construction tasks without needing to join lines mid-run.

Specs & Attributes

Typical Applications

• Laying courses of brick and block work
• Setting out foundations and footings
• Aligning block paving runs
• Garden and retaining wall construction
• Marking render coat height
• Setting out straight fence line runs

How to Use

• Drive line pins or position line blocks at each end of the planned course.

• Tie or loop the brick line firmly around each pin or block.

• Draw the string taut between anchor points so it twangs lightly when plucked.

• Position the line at the height of the finished face of the next course.

• Lay bricks or blocks to the string, keeping a trowel-blade gap between the arris and the line.

• Re-position the line to the next course height and repeat.

Frequently Asked Questions (FAQs)

• Why choose nylon over cotton for a brick line?
  Nylon resists moisture and mildew, while cotton absorbs water and can deteriorate over time. Nylon also holds tension more consistently in wet or damp site conditions.

• Why does a brick line need to be alkali-resistant?
  Fresh mortar and cement carry a high pH level. Without alkali resistance, the string can degrade when it comes into direct contact with these materials during use.

• How taut should a brick line be?
  Pull it tight enough to twang slightly when plucked, with minimal mid-span sag. On runs over around 4m, add a mid-span support (known as a tingle) to maintain a true, straight guide.

• What is a tingle, and when is one needed?
  A tingle is a thin metal clip or folded-paper support placed under the line at its mid-point on long spans. It prevents the string from sagging and giving a false course level.

• Can a brick line be used for tasks other than bricklaying?
  Yes. Builders use them for setting out foundations, aligning paving, marking garden borders, and keeping fence posts in line. They suit any task requiring a straight reference point on site.

Summary

The Blue Spot Tools Hi-Vis Brick Line (34650) delivers 100m of braided nylon string for bricklaying and site layout. High-visibility colour, built-in elasticity, and resistance to both abrasion and alkali make it a practical choice for building work.
