Great videos , I would love to see you do one on a stone welsh cottage .Here in wales we dont have damp courses quite often and even zinzer doesnt stop brown stains coming through our stone walls . Will now get a bigger dehumidifier , only got a 12 litre one for the bathroom and that weighed enough ,taking it up and down the stairs
Thank you for your kind words about the videos! I appreciate your interest in applying these concepts to Welsh stone cottages. You're right that the fundamental principles remain the same, regardless of the building material. Here's an expanded explanation and some advice: Stone walls and dampness: The primary cause of dampness at the base of walls, even in stone cottages, is often condensation rather than rising damp. This applies whether there's a damp course or not. Brown stains: The stains you're seeing might be related to penetrating damp (rainwater) or hygroscopic salts, which can absorb moisture from the air and create damp patches. These don't necessarily indicate rising damp or serious water ingress. Applying Dew's Law: The key is to keep internal vapor levels (as measured by dew point) below the outside temperature. This prevents condensation on cold surfaces like stone walls. Monitoring: Use data loggers to track temperature and relative humidity both inside and outside. This will help you understand your cottage's specific moisture dynamics. Dehumidification: A larger dehumidifier can indeed be helpful, but it's important to use it strategically. Focus on maintaining overall good ventilation and managing moisture sources first. Ventilation: Ensure your cottage has adequate ventilation, especially in high-moisture areas like the bathroom and kitchen. Heating: Consistent, gentle heating can help keep wall surfaces above the dew point, reducing condensation risk. Breathable materials: When redecorating, use breathable paints and plasters that allow the stone to 'breathe', helping manage moisture naturally. For more detailed information and strategies, you can check out damp.ai, which provides in-depth guidance on managing moisture in various building types. I hope this helps with your Welsh stone cottage! Let me know if you have any more specific questions about your situation.
@@dampsurveys769 Thanks for that , definitely a work in progress. We have installed fans on the bottom of our radiators in the living room to get the air circulating , relatively new invention , works quite well at circulating the heat , they just clip on with magnets and come on when the temperature gets above 40.
