While the masonry paint is a coloured paint, the masonry cream is an invisible waterproof treatment, which allows both painted and non-painted properties the ability to prevent penetrating damp.
Unfortunately, you can't just paint over damp or mould in the hope it will disappear. Even if you use waterproof paint, it can still seep through over time. Depending on how bad the problem is, you may be able to remove the mould by cleaning the area without repainting.
The best way to treat penetrating damp is to apply a water-repellent treatment like Stormdry Masonry Protection Cream to halt further dampness and allow walls to dry out.
Open windows and doors to allow air to circulate freely, and use fans to speed up the drying process. If possible, use a dehumidifier to remove excess moisture from the air. A dehumidifier absorb moisture from the air, which helps to reduce dampness and prevent mould growth.
Satin and semi-gloss paints have a higher sheen value, meaning it provides a harder finish that proves more moisture resistant. Along with the benefits of moisture resistance, satin and semi-gloss finishes are also very washable and scrubbable.
This is ideal for damp properties, as it will prevent moisture from building up on the surface. The most common breathable paint is called claypaint, but some emulsion paints will also have breathable qualities.
Damaged Or Blocked Guttering – This is the most common source of excessive water affecting your property and causing penetrating damp. Fortunately, it is a very simple fix with regards to stopping penetrating damp. Unblock the gutters or repair the deficiencies in your downpipes and gutters.
Use fans to move air around the damp walls. Also use dehumidifiers, which can help remove moisture from the air and walls. Professionals use tools like moisture meters, infrared imaging devices, dehumidifiers and heavy-duty fans. That ensures the walls are truly dry before further repair, painting or refinishing.
Microshield. Permagard's Microshield is an effective high-performing water repellent suitable for external use on masonry materials such as brick, concrete and stone. In one single coat, this microporous water repellent will protect masonry materials against penetrating damp.
Unfortunately, standard masonry paints do not prevent this absorption as they are most often acrylic-based masonry paint. Acrylic masonry paints can actually absorb some moisture, which is why they are often referred to as 'weatherproof' or 'weather resistant', rather than waterproof.
Penetrating Damp Internal Wall Treatment
Costs vary significantly between areas and suppliers, but a rough average is around £70 per metre of the treated wall or around £280 per wall. The costs could easily reach several thousand pounds if you need to treat every wall.
Using a masonry protection cream will not only prevent penetrating damp but also provide a thermal barrier helping to prevent heat from escaping your property.
Made with a unique solvent-based formula that combines a state-of-the-art waterproofing resin with Portland cement to create a coating that stops up to 34psi of water pressure. WaterTite® Waterproofing Paint can be applied to dry, damp or wet surfaces, so water problems can be cured immediately.
Paints designed for damp often have properties that treat the problem as well and stop it from coming back. They also let moisture escape meaning there won't be a build-up of damp. So if you've fixed the root cause, using a specially formulated damp paint should put a stop to the problem for good.
Place one or more fans in front of the damp spot and turn them to their highest setting. This helps dry the wall and also gets moisture out of the air. If the fan has an oscillation feature, you can use this to clear more than one damp spot that is within its reach.
No mold doesn't always grow after a leak. If the temperature isn't right or if the leak is properly dealt with quickly, there's a chance that mold spores won't be able to take root or grow.
To resolve rising damp, either a chemical or osmotic damp proofing course (DPC), or a new damp membrane must be installed. A DPC is often used and is injected via holes in the masonry, the DPC repels water whilst a damp membrane acts as a physical barrier to stop damp.
Penetrating dampness occurs when water leaks through roofs, windows, and cracks in walls, causing damp patches on internal walls. Penetrating dampness is generally not covered by buildings and home insurance, as the gradual deterioration of the building materials mostly causes it.
To determine which one is the problem, look for discoloration and mould on walls and ceilings. If the dampness is due to condensation, the walls will be cold and the air will be humid. If the dampness is due to penetrating dampness, the walls will be damp and there will be water stains.
Tanking is a reliable way of dealing with the effects of penetrating damp once the root cause has been fixed.
Paints with a glossy sheen—like satin or semi-gloss—are best for humid rooms. Instead of absorbing moisture like matte or eggshell paint, they deflect it. Glossy paints can resist moisture because they have a more complex finish. Another benefit of using glossy paint is that it is easy to clean.
If you are dealing with a leaky roof that is letting water in, Rust-Oleum's waterproofing Fillcoat Fibres paint will be a great solution. This waterproofing paint can also be applied directly to wet areas and in any weather conditions, so it's perfect for quick repairs.
Dryzone Anti-Condensation Paint has been developed to reduce condensation and mould growth on interior walls. The paint is simply applied to clean and debris-free surfaces using a standard paintbrush or roller, as per standard decorating practice.
