Faithfull Chalk Line - Medium Cotton - 18m - Box of 12

Each chalk line in the box has a length of 18 meters.

Yes, it is suitable for outdoor use, but chalk lines may be less visible on very dusty or damp surfaces. It's designed for general building trade applications.

Cotton lines can often hold chalk slightly better for a more consistent mark on certain surfaces, though they may be less durable than synthetic alternatives in harsh conditions.

Open the chalk line housing, pour the chalk powder into the designated reservoir, and close it securely. Refer to the specific chalk line mechanism for precise instructions.

No, the chalk line is typically sold empty and requires chalk powder to be added by the user.

Faithfull offers a 30-day money-back guarantee if you are not completely satisfied, provided the returned items are in their original packaging and condition.

Ensure the chalk reservoir is adequately filled and the chalk is fine grade. Check that the line is taut and plucked with sufficient force. Clean any debris from the line.

Carefully lay the line out on a flat surface and gently work out any knots or tangles. Avoid forcing the line, as this can damage the cotton fibres.

Verify that the reservoir lid is securely closed and properly sealed. Inspect the housing for any cracks or damage.
