How Can I Prevent Water Damage To My External Walls?

This guide provides tips on how to protect your exterior walls from damp by using DIY methods and the right tools. The optimal way to protect structure, siding, and exterior finishes from moisture damage is to design the outer layer of the house as a decorative “rain screen”. Regular maintenance for waterproofed exterior walls may include inspecting for cracks or damage, cleaning gutters and downspouts to ensure proper drainage, reapplying sealants or coatings as needed, and addressing any existing damp walls.

Waterproofing your basement foundation is crucial for protecting your home from water damage. Groundworks recommends interior basement waterproofing as the most effective method. To effectively waterproof your exterior walls, follow these steps:

1. Repair any cracks. If you see any cracks in your walls, repair them before proceeding with waterproofing.
2. Clean the walls. Apply a waterproofing sealant. Install a drainage system. Install a vapour barrier.
3. Regularly maintain the exterior walls by applying high-quality waterproof coatings and sealants, installing weatherproof solutions to create a protective barrier, and ensuring proper moisture control.

Most methods for protecting against damp externally are relatively simple DIY tasks, such as applying facade cream or installing a new damp proof course. Plastering can improve aesthetics, make walls more solid, and protect them against moisture ingress. Waterproofing membranes, insulation materials, and crystallized powder and liquid concrete admixtures are applied to building walls to prevent water and moisture ingress.

To prevent moisture build-up against exterior walls, trim trees and bushes, store wood and other porous materials away from your house. Step flashing to the roof, avoid frozen pipes and ice dams, treat siding, damp proof the foundation walls, and add drainage to your house.

How to waterproof an external house wall?

Waterproofing exterior walls is crucial for maintaining property integrity and preventing structural damage. To effectively waterproof your walls, follow these simple steps:

1. Inspect your walls for cracks, gaps, or signs of damage. This can be done visually or using a moisture meter. If any damage is found, repair it before proceeding with the waterproofing process. This ensures proper adhesion of the waterproofing material and long-lasting protection.

2. Clean your walls thoroughly. Dirt, dust, and debris can hinder the adhesion of the waterproofing material. Use a power washer or hose to wash the walls, removing dirt, grime, or mold. Allow the walls to dry completely before proceeding with the next step.

In summary, waterproofing exterior walls is a crucial step in maintaining property integrity and preventing structural damage. By following these simple steps, homeowners can effectively waterproof their walls and protect their property from the elements.

What is the best waterproofing method for exterior walls?

External walls of homes should be protected from heavy rainfall, freezing winters, and scorching summers. They are most susceptible to damage during monsoons, as they are exposed to rainwater, high humidity, water, and moisture. These factors, combined with extreme temperatures and extreme humidity, can lead to the growth of algae on the surfaces. To protect your walls, consider using products like Silicate Based Sealer, Waterproof Paint, and Plaster Additives.

These products react with concrete and masonry to create a waterproofing coating, providing better performance compared to acrylic paints. Plaster additives can also be used to enhance the performance of your exterior walls.

What is the most common way to protect exterior walls against moisture?

Protect against damp by installing exterior wall waterproofing, which can be done through DIY tasks like applying facade cream or installing a new damp proof course. If you already have damp walls, it’s crucial to address the cause, such as leaky gutters, pipes, crumbly mortar, or crack stitching repairs. The method depends on the type of damp. Regular inspections of the exterior are essential for preventing damp and structural issues, especially on external walls.

Understanding different types of damp and their appearances can help identify warning signs and fix issues quickly. Common damp and structural repair issues include preventing water ingress through walls, which can occur through old mortar or heavy rain absorption by brickwork and masonry.

How do I stop water coming through my external walls?

It is recommended that a breathable waterproofing masonry cream, such as Stormdry Masonry Cream, be applied to the outer walls in order to create a hydrophobic barrier against moisture ingress. The cream is designed to absorb Stormdry over a period of 24 hours, thereby maintaining the visual appearance of the brick wall. Breathable, colorless water repellents form a barrier along the pore structure of masonry, allowing the material to breathe naturally and enabling the escape of moisture.

How to damp proof outside walls?

Damp is a significant risk to property, and if left unchecked, it can escalate quickly. To protect your walls from damp, it’s essential to repair cracks, check guttering, repair mortar, inject a new damp proof course, and conduct regular inspections. Adopting a preventative approach can significantly improve damp-resistance and potentially save you significant costs in the long run. By addressing cracks, checking guttering, repairing mortar, injecting a new damp proof course, and conducting regular inspections, you can protect your walls from damp and ensure their longevity.

What can I put on outside walls to prevent damp?

Waterproofing coatings like waterproof masonry paint and masonry cream are used to create a water-resistant surface on exterior walls, preventing rainfall from entering the building. Emperor Paint offers both colored masonry paint and clear masonry cream, which create a water-repellent surface while remaining breathable. These coatings come with a lifetime guarantee and have been shown to keep treated walls up to 6°C warmer on average compared to untreated walls.

Emperor Masonry Paint is one of the most durable masonry paints available in the UK, as it prevents peeling and flaking due to its ability to prevent moisture from causing the paint film to fail. Painters World stocks Emperor Masonry Paint in 12 standard colors, including some fantastic exterior shades.

How to stop water leakage from an exterior wall?

To prevent seepage in buildings, use high-quality, water-resistant paints containing elements like silicon. Seal gaps between window and door frames and walls, remove plasters from dampened areas, and apply white cement or mortar. The site needs to be plastered again with high-quality paints to prevent further damage. Immediately repair cracks and fissures with cement and mortar. Address water leakage from taps or tanks individually. Building cavity walls prevent moisture transmission from exterior to interior walls.

Prolonged exposure to heavy rainfall and heat can lead to cracks and fissures on the outer walls of buildings, allowing water to enter these crevices, causing damps and seepages. Leakage from pipes, cisterns, poor-quality raw materials, and construction issues can also contribute to seepages. Regularly plaster the outer walls with suitable quality materials, use premium water-resistant paints containing silicon, waterproof pipes and cisterns, and use methods like shot concrete or pressure grouts to prevent external wall seepages.

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.
