Damp Walls
Walls can become damp for a multitude of different reasons. Damp problems in walls are often only noticed once internal damp symptoms become apparent. Such symptoms include damp patches, black mould growth, hygroscopic salt contamination and crumbling plaster. It is important to note that the source of the damp problems could be caused externally or internally, even though the most visible symptoms of dampness are most apparent internally.
It is essential to investigate the source of any damp issue, as the wrong treatment can often make matters worse. It is advised to seek the help of a professional to survey the damp to find where the problem originates from. If the source is external or on the outside walls, the problem is likely to be penetrating damp. If the source of the dampness is internal or affecting the inside walls, the problem is likely to be condensation or rising damp.
The most common source of dampness on external walls is penetrating damp, often as a result of exposure to wind-driven rain. Treating penetrating damp and damp-proofing brick walls can easily be achieved with Stormdry Masonry Protection Cream. Stormdry is a breathable masonry waterproofer, which protects external walls from rainwater ingress for 25 years.
External walls can also suffer from rising damp. Treating damp walls and waterproofing them in such cases can be achieved by the use of The Dryzone System, the complete rising damp renovation range. Dryzone Damp-Proofing Cream or Dryrod Damp-Proofing Rods can be used to stop rising damp at its source, whilst the Dryzone Express Replastering System or Dryzone Renovation Plasters allow for fast and a renovation of affected walls.
Damp on interior walls most often develop due to condensation. Water contained in the air condenses on cold surfaces, such as walls, resulting in a moist environment perfect for mould spores to thrive. To stop damp on internal walls and prevent mould growth caused by condensation, a correct ventilation and heating regime should be adhered to. However, this can prove difficult in some situations due to lifestyle necessities. An easy solution to cure damp on internal walls is to paint walls and ceilings with Dryzone Mould-Resistant Emulsion Paint. The paint damp-proofs internal walls against condensation and protects for at least 5 years from unwanted mould growth. It is an easy and efficient way to deal with damp internal walls caused by condensation.
Damp walls in houses can also develop as a result of rising damp. When groundwater rises up internal walls it can result in decaying skirting boards, efflorescence, black mould growth and the peeling / blistering of wall paper and paintwork. One option to damp-proof walls internally against rising damp is the use of the Dryzone Express Replastering System. It is a fast and efficient way of dealing with damp internal walls. The treatment of rising damp and replastering of internal walls can be achieved in just 24 hours. Alternatively Dryzone Renovation Plasters in combination with either Dryzone Damp-Proofing Cream or Dryrod Damp-Proofing Rods can be used to treat damp internal walls.
The Dryzone System is a damp-proof treatment for walls suffering from rising damp. The system has two options for drying out damp walls; Dryzone Damp-Proofing Cream and Dryrod Damp-Proofing Rods, as well as two options for replastering walls after treating damp on internal walls; the Dryzone Express Replastering System and Dryzone Renovation Plasters.
The Dryzone Mould-Resistant Emulsion Paint is ideal for treating symptoms of damp on internal walls caused by condensation.
The paint has been formulated to stop the regrowth of black mould for at least 5 years.
Damp-proofing interior basement walls can be a complex task. Basement walls are susceptible to the ingress of moisture and the correct damp wall treatment has to be chosen. This can mean tanking walls or choosing damp-proof membranes for walls.
