Damp-proofing walls is essential to prevent damp penetration and ensure the safety of your home. To do this, use a lint-free cloth to wipe down damp areas and set a dehumidifier in the room where you are damp-proofing. This will pull moisture out of the air as you knock it out of the wall with your cloth.
To identify common causes of damp walls, such as water stains, damp patches on walls or ceilings, musty smells, and warping of wooden floors, consider investing in a moisture meter to help you identify the quality of your home’s existing damp proofing. Installing a damp proof membrane or damp proof course (DPM) in buildings can prevent unwanted moisture from seeping into the inside walls of a property.
Some indications of damp walls include wall discoloration, mold formation, and a persistent, unpleasant smell. The most common way to damp-proof a wall is to apply a damping resin, epoxy, or spray to the surface of the wall. You can also use plastic sheeting to cover exterior wood walls or silicone to fill in gaps in masonry and keep dampness out.
Damp proof injection fluids are a trusted and reliable solution for treating rising dampness in walls. To locate the cause of damp walls, fix this before continuing. Buy or hire a dehumidifier to completely dry out the room and use a stain blocker to prevent further dampness.
The membrane damp-proofing method entails inserting a physical layer, typically made of high-density polyethylene, into the walls or flooring to prevent water. Paint walls and ceilings with Dryzone Mould-Resistant Emulsion Paint to cure damp on internal walls. Use a Condensation Mould Kit to remove any mould from walls and surfaces, then paint with a damp seal.

What can I put on my walls to prevent damp?
Damp proofing is a solution that can help create a dry wall in homes. It involves using damp proof membranes, paints, slurries, and water-resistant renders and admixtures. Damp can damage internal decorations like flaking paint, crumbling plaster, curling wallpaper, and rotting skirting boards, and can change the atmosphere of a home from cozy to unsightly. If left untreated, damp problems can lead to more serious complications. This guide focuses on damp proofing methods for interior walls.
How to waterproof interior walls?
This article discusses the importance of interior wall waterproofing, a cost-effective and easy method for protecting homes from water damage. It covers various waterproofing paints and sealants, including basement walls, and provides tips on choosing the best one for your specific situation. Understanding these factors can ensure that your interior wall paint remains dry and structurally sound for a long time. The article also covers the different types of waterproofing methods and provides tips on choosing the best one for your home.
How to get rid of rising damp on internal walls?
Rising damp can be effectively and economically treated using a damp proofing injection cream. PermaSEAL PRO DPC Injection Creams are available in complete kits or individual cartridges. The cream is injected into holes in the mortar course, reverting to a liquid to penetrate bricks and achieve complete absorption. As it cures, it creates a powerful water-repellent barrier and a new chemical DPC that prevents water from rising up the wall.
Alternatively, a new damp proof membrane can be installed, which involves removing bricks along the failed mortar course and installing a new physical damp proof membrane. To treat rising damp on internal walls, remove any wallpaper and plaster back to the bricks or substrate, as well as the external wall of the property.
Can you damp proof a solid wall?
The following video illustrates the application of Damp Proof Injection (DPC) to inhibit capillary dampness in masonry walls. The silicone-based cream is introduced into 12mm holes that have been drilled into the bed-joint using a straightforward injection applicator. The cream diffuses rapidly before curing, thereby creating a water-repellent damp-proof course that effectively treats rising damp in brick and masonry walls.
How do you remove moisture from inside walls?
In order to guarantee that the walls are adequately dry prior to undertaking repairs, painting, or refinishing, professionals employ a range of tools and techniques. These include the use of moisture meters, infrared imaging devices, dehumidifiers, and heavy-duty fans, which are deployed to facilitate the movement of air around damp walls and the removal of moisture.
What is the cheapest way to waterproof a wall?
The most cost-effective method for waterproofing a basement is the application of a waterproof paint coating. This can be completed for a relatively low cost per square foot.
How do you waterproof a solid wall?
Water repellent creams and sealants can be applied to un-painted brickwork to protect it from water penetration for up to 30 years. These creams work by soaking into the substrate, reducing water absorption and providing a long-lasting invisible barrier against water penetration. They line the capillaries of the masonry, reducing water absorption and protecting the substrate. Additionally, they allow the walls to breathe, allowing damp to evaporate and drying out. One coat of façade cream, such as PermaSEAL Facade Cream, Remmers’ Funcosil FC, or Microshield Ultra, can protect up to 30 years of exposed brickwork.
What is the best damp proofing method for walls?
Damp can be caused by various factors, such as leaking pipes, roofs, gutters, or poorly maintained exterior walls. The most effective method for rising damp is installing a chemical damp proof course (DPC) through brickwork or masonry to prevent moisture from rising up. Penetrating damp can be treated with an exterior wall coating.
Ignoring the problem and hoping it will go away is not a solution; it will worsen health and cost more in the future. Using a dehumidifier can reduce ambient moisture but does not cure the damp source. Opening windows and ventilating the house can help reduce damp risk, but it is not a solution unless the source is fixed. Internal damp proofing has limited success, especially with dry lining boards, and interior damp proof paint is a waste of money and a false sense of security.
Damp is water, and damp proofing one section of the wall may cause water to flow and find another place to emerge. Water in bricks of the wall will freeze in winter, undermining the structural integrity of the house. Having a new injected DPC course only cures rising damp, but it does not cure penetrating damp and may still see mold growing on upper interior walls.
A damp proof exterior wall coating is the most effective way to cure damp and mold permanently, comes with a 20-year guarantee, lowers heating bills, and prevents interior walls from feeling cold even with heating on.
How to stop moisture in walls?
Wall dampness is a common issue in homes, resulting from air condensation, moisture seeping into walls, leakage issues, or rainwater entering homes. It is a symptom of larger problems and is usually detected when there are dark blots on walls, cracks in ceilings, and peeling paint. To protect your home from moisture and dampness, use water-proof sealants, paints, and membranes. Additionally, ensure good ventilation to keep moisture out of your home.
Monsoon safety involves repairing cracks, leakages, and redoing wall construction to avoid moisture and leakages. Replace old leaky pipes with new fixtures to maintain a beautiful home. Effective wall dampness solutions are crucial for your home’s wellbeing, as they help prevent molds, fungus growth, seepage, leakage issues, peeling paint, and overall structural damage.
How do you stop dampness from coming through walls?
To prevent the accumulation of moisture on interior walls, it is essential to implement effective ventilation strategies, maintain consistent temperatures throughout the home, and conduct regular inspections for potential leakage or cracks in the gutters, walls, and roof.

I have been diagnosing damp issues for 28 years and I have yet to recommend drilling and injecting a building of cavity wall construction. When you were drilling the outside I couldn’t see the original DPC which leads me to conclude that the ground levels have been raised above it and the sub floor vents. The problem with so called ‘Damp Companies’ is that they always diagnose ‘Rising Damp’ and charge the customer thousands to mask the issue rather than finding and rectifying the cause.
at 3:35 we can see that the external paving height is simply too high, causing the wall above the DPC to become damp. The injection in reality does nothing. It’s noted in the article that by removing the plaster the wall dried out, this shows you are not dealing with an endless supply of ground water i.e rising damp. The plasterboard will give you some nice separation from the damp wall and so in effect you have actually reduced the chance of the damp coming though to the decorated surface but in reality the brickwork behind will still be damp. But as with most damp, if it’s not effecting the decorated finish the homeowner will be happy enough!
Counting the brick. It’s 8 coarse inside 10 coarse outside so that wouldn’t of fixed it would of it. I aunt a clue but surely you have to drill on the same line both sides to make it sealed. Or am I looking into it too much surly it had should of been done 2 corse higher outside isn’t it ment to be 2 brick higher from ground level
Internally there are 8 courses of brick above the flooring, externally there are 10 courses of brick before the paving is reached – so the question is this: where is the DPC? I have a hunch that the DPC is either at the 10th course of bricks just barely above the paving OR 1 brick below. The house appears to be a cavity wall construction based on the ‘stretcher’ bond walling as opposed to 1 brick thick walling of older housing. I would have lifted a paver outside and had a look for the DPC – but whatever is going on the cavity wall is being breached – an option would have been to put an ait brick in for ventilation.
Great article Mark. I have an internal wall that is non load bearing and it has bad rising damp as we have no damp proof course throughout the apartment. The wall has the orange blocks rather than bricks, can I use the rods rather than the liquid injection you are using and the mortar is very thin can I put the rods into the blocks, thank you for your help
