Lucky you! I don't think that their technical datasheets recommend primer and undercoat - they recommend stripping back to bare wood and then priming with their Weathershield Aquatech basecoat: http://dulux.trade-decorating.co.uk/web/pdf/datasheets/401.pdf It's something to spend your...

The inside of a house is typically warm, with the capacity to contain considerably more atmospheric moisture than the colder outside air. Where insulation is present, there is a temperature difference from the outside to the inside. If there are any gaps or imperfections in the...

Sounds like a typical Portsmouth fin de siècle red brick terrace build. I doubt if closing the top of cavities with a little insulation would do much at all. Several of the cavity walls I have seen communicate with the outside through various holes and cracks in the outer skin. Have the...

If you have removed the damp the mould will not regrow. Mould spores are always present. Condensation occurs when the temperature of the air is higher than a cold surface. If the temperatures of air and the surface are the same, condensation will not happen, and the damp will dry off...

If sodden and clay-like, it is old lime mortar, not cement - it will get wet, so it sheds water off the outside wall in driving rain. It then will nor absorb any more. The drill test is into the middle of the brick, especially on the inner leaf to rule out sodden bricks from penetrating...

The installers of the UPVC windows have possibly left uninsulated voids around the window frame and have just used sealant to close the gap In effect, there is a cold area communication between the outside and internal window reveals which then get cold, and drenched with condensation. The...

Reading through your posts, you have a cavity wall (facing the weather = South westerly?) with an external render, with a coating that is flaking off. Internally, you imply that have damp which you believe is penetrating. If you want to recoat the decoration of the render, removing the...

I think your analysis is correct - modern materials and modern living - higher air temperatures on demand, but without draughts and constant air changes due to open fires in the winter and better insulation causes condensation and mould. It may be countered by use of unheated fans to move...

http://www.devonearthbuilding.com/leaflets/leaflet.pdf Page 3 has an excellent diagram that describes your situation. Later there are recipes for render and limewash, but there may be other mixtures more appropriate to your property.

The impervious cement render and paint is still the problem, whether the cob is reinforced with stone or not. Wind, sun, and atmospheric temperature and humidity changes cannot act on the surface of the wall, and it will become increasingly damp, the clay in the cob will become plastic, and...

What is the render? If it is quite hard to break then it is cement, I would guess. It has the grey component of cement between the grains and the colour of the sand - e.g. yellow or red, depending on source. Lime is softer and usually whitish, creamy or pinkish, - usually burnt from local...

NE is the coldest corner of a building in the UK. No sun, and the raw Arctic and Scandinavian winds. What is the composition of the render and the textured finish? Cob walls should have a breathable render that is basically lime, and should not have a latex paint coat. If the render cannot...

Thanks for answering. A north east exposed corner with solid red brick wall with no insulation, rendered above damp course - on one side (northern side by any chance?), not the other - DPC of 2 courses of Blue bricks, probably a porous lime mortar from 1928 because that's what was commonly in...

What is the compass orientation of the affected corner? Is the corner sheltered or exposed? Is the wall solid (how thick from outside to inside finish) or cavity (what size cavity)? Cavity moisture bridge check carried out? Any cavity insulation (what type)? Rendering or cladding to outside...

No-one mentioned the "join" between cables either! - what was it - TV coax connectors, chocolate box or just twisted the conductors together and taped up?

There are some folk with an aversion to cleaning brushes, and use them as throwaway items. This obviously does not apply in this case. Emulsion, vinyl, exterior paints, textured paints, wood stain on fences, cutting in on ceilings and walls, applying paint to mouldings, Wallpaper repairs...

[/url] There are many junk science sites on the web. Believe them if you wish. Here's what that webpage starts with: Here's the relevant quote from the EPA The EPA does recognise that Bleach kills mold - but does not recommend it for routine cleanup because it may not cleanup all...

Not based in fact, at all, I am afraid. Thick Bleach is about 5% surfactants - anionic and ionic detergents, specifically to wet the surfaces it is applied to and carry the hypochlorite solution along. If damp or condensation can penetrate a surface, bleach can do it better. Unlike...

Apply the paint quickly with a gloss roller, then lay off using a lightly loaded brush, with even long strokes. Do not overwork the paint. You should complete a 3 by 1 foot surface in less than 5 minutes. Dispose of the used roller at the end of the day. Personally I hate non-drip...

JohnD gives this advice elsewhere - it will inform you that you have condensation http://www.diynot.com/wiki/Building%3ACondensation-in-Houses Many of the postings here are argumentative, and thus not helpful. The original question (entitled "Mould issues") was: Yes, it's...
