Roger carries out some tests to see if the claims made by Safeguard Stormdry are watertight.
MORE ON STORMDRY
Stormdry has been tested to EN ISO15148:2002 (E), demonstrating its effectiveness on concrete, mortar, brick, and sandstone.
Stormdry masonry protection cream is applied to masonry in a single coat by means of brush, roller, or spray. Once applied, it penetrates deeply into the masonry before curing to form a colourless, breathable water repellent barrier.
WHAT IS PENETRATING DAMP?
Rain penetration through masonry (known as penetrating damp) is a common problem in buildings - particularly in the case of those of solid wall construction.
The problem is also increasingly common in buildings of cavity wall construction where cavity wall insulation has been poorly installed or used in walls that are not suitable for cavity wall insulation.
Other paths through which rain can cross through a cavity wall include incorrectly positioned wall ties and mortar obstructions in the cavity.
Penetrating damp is caused by water permeating through walls from the outside. It can occur at all levels of a building but is more prevalent higher up.
It is possible for damp to move within walls but this horizontal movement differs from the vertical movement of rising damp. Penetrating damp is usually caused by the following:
Porous Walls - Aging bricks lose the ability to keep out rain penetration.
Spalled Bricks & Degraded Mortar - Damage to brickwork allows water to penetrate.
Building Defects - Defective guttering and downpipes, roof damage, dilapidated or poorly installed windows. In this case, fix the root of the problem before applying Stormdry to boost your protection.
