We have condensation on th back stairs of our flat. We are having it skimmed shortly and we have been advised to put a waterered down mist coat of emulsion on before applying a coloursed emulsion on top. My question is if i would put the condensation paint on first before the mist coat or would the condensation paint do the same job as the mist coat? The sealer coat needs to be applied to the new plaster as advised by your plasterer, then once on and all is dry you can finish with your choice of Anti-Condensation Paint.
Hi I had recently installed a built in cupboard to one of the alcoves in the bedroom, which is an outside wall. After a few weeks there was mould all over the back panel. The wall although not wet had mouldy patches and slight damp where the skirting board was. There was no ventilation into the cupboard. The wall surface is prepainted. What is the best thing to do before I fit the cupboard back to the wall?
Your suggestions will be most welcome. Thanks for your message. In answer to it, we would suggest that after cleaning with a fungicidal solution, that you prime the surface with Zinsser B-I-N and then apply coats of an Anti-Condensation Paint. I have a small conservatory off the lounge. The floor gets very wet as does the walls around the skirting boards. Will Zinsser Watertite paint help?
What do you suggest for the tiled floor? If we are talking about damp coming through to the surface from outside then Zinsser Watertite would work on the walls if they are bare brickwork. We would still recommend that the source of the damp be rectified from the outside of the conservatory otherwise the Watertite will eventually fail. If the moisture on the walls is on the actual surface due to the formation of condensation, then we would recommend Rust-Oleum Anti-Condensation Coating.
The floor is a different issue, if the moisture is penetrating up through the floor then really the tiles would need to be lifted and a damp proof membrane such as our Damp Proof Coating be applied.
Hi, have just had new skirting boards added to a basement room. A small amount of damp comes from underneath despite best efforts to solve the source and has started to mark the wood. What are the best gloss products to prime and paint the skirting with to try and reduce the probable long term effects?
Assuming it is a concrete floor with plastered walls, dampness may be coming up through the floor and into the wall, the skirting boards may be getting damp from the floor and wall. Hi, we have a 30s solid brick house. In one room we have a wet spot about a metre and a half up the wall. I found this sport after removing a built in wardrobe. I think it may be a slight crack in the white rendered wall outside. I am considering painting the wall thinking that should be good enough to seal any cracks.
The internal wall has hairline cracks in the plaster. I put a dehumidifier int he room and it drew nearly two litres of water in a day. The wall is now dry so I would like it to paint it. What do you think about the possible cause of the wet? We would advise using Rust-Oleum Mathys Murfill Waterproofing Coating for the external, assuming the exterior crack was the source of the incoming damp, once the interior wall surface is dry they can paint with Zinsser B-I-N followed by Perma-White.
Your help would be greatly appreciated, Steve. Treat the mould thoroughly, ensure the walls are completely dry then apply 2 coats of Zinsser Grade 1. As well as an extractor fan, ventilating the room after using the shower etc will keep condensation to a minimum.
I tried to submit a previous message, no idea if it went through because apparently I am a robot! I am looking for advice on whether I am have damp or condensation and of course what to do about it. I have a black spotty patch on the wall behind my toilet in my bathroom. Although again, I am unaware of any exterior issues that could be causing moisture to enter the bathroom.
Any suggestions on how to determine which it is? It sounds like this will be warm air hitting a cold wall surface behind your toilet and condensing — leaving water droplets on the surface which is then forming mould over time. Hello I have a condensation problem I think. Thanks Simon. Both products are available to order right now on our site, links contained above to the product pages. I have a converted cellar which has not been decorated for some 15 years.
I have also added more ventilation to the cupboard to prevent any more problems. For this we would advise Zinsser Perma-White Interior. It will take to the Gardz and can be used on both surfaces, wood and plasterboard to provide a durable, non yellowing mould resistant coating.
Hi I have a metal car port ,when the weather changes I get a lot of condensation in early morning ,if I paint the underside would that stop the condensation. Our recommendation to coat your Plastisol metal sheet roof internal, underside to help prevent the formation of condensation forming, would be as follows;. It may be that there is no DPC in place, or the footpath outside the building is built up above the DPC … either way, there is evidence of either rising or penetration damp in the lower part of spme of the walls which is causing paint peeling — somewhat unsightly.
Is there a paint that I can apply to the affected areas that will at least not require renewal too regularly? Watertite cannot be applied to plaster, it is only suitable for masonry surfaces such as render, concrete, bricks etc. If you contact our Technical Support Team at [email protected] with some more details of what you require, they may be able to recommend a suitable product for you. I live in a ground floor converted flat which has ongoing damp issues.
In the bedroom we have a big bay window which is north facing and the walls are ice cold and damp to touch at this time of year even with the heating and dehumidifier on. I have had extra air bricks and cavity cleared to help air circulation however I have used Zinsser watertite on advise from a builder but i feel that this has exacerbated the condensation problems as now the walls wont allow any moisture to escape. I am at the point of thinking it would be best to strip all the plaster off and start again as I have a 6 month old son who is sleeping in that room too and there is mold growing on all the furniture i need to find a solution to try and resolve this issue.
We have green mould growing up from the skirting in one corner mainly of bedroom wall which is a cold outside wall. Have tried a bleach solution and small dehumidifier — which have helped — but would like to try something else esp. The following recommendation is based around this being a condensation issue, rather than penetrating damp — for which we would advise;. Clean surfaces ensuring all existing paint is sound and free of dirt, dust, grease, wax, wallcovering adhesive, soap film, loose paint or other surface contamination 2.
Leave to dry fully before painting 4. Prime mould stained areas with Zinsser B-I-N 5. Apply 2 coats of Zinsser Perma-White Interior in the desired colour and finish.
Please let us know if there is anything else we can help you with — all product recommendations above link to the products on our store, too. Victorian house with fitted wardrobes on exterior walls.
Walls inside the wardrobes have insulating paper on them and are also painted but mould from condensation has developed on the exterior corners. I appreciate I need to strip the walls of existing paper and increase ventilation. Once that is done what would you suggest? Can I paper it again with insulating paper or tiles which would be easier to fit as the space is tight and use your products too?
Thank-you for your question. As discussed in the post, we would recommend Zinsser Watertite for bare plaster — which can then have new wallpaper applied over it. How can I stop damp returning to wall areas around furnishings? Please let us know if there is anything else we can help you with via this post, email or on our Facebook page.
I have a Kingspan insulated wall in the living room, currently painted with emulsion which is showing condensation marks where the fixing nail heads have been applied. Which product would you suggest I use to paint over the marks before I apply a suitable emulsion or wallpaper.
You could then try sealing the complete wall, not just the nail heads with a full coat of Zinsser Bulls Eye followed by an emulsion. If you could supply photos showing the problem we may be able to advise further — simply email them to [email protected]. You will need to take the window out to completely stop condensation from forming on it. It is difficult to answer without knowing a bit more about the issue, as something more onerous could be going on here.

Bob 8th February at pm. Mark Whiley 9th February at am. Good morning Bob, Without an industry professional carrying out a survey on the property we really have no way of knowing what exactly is causing this but from the situation you have explained it sounds like it may be condensation sitting on the surface of the paint in that area making just the exposed surface wet or it could be something as simple as a stain on the paint that looks like a damp patch.
Mark Whiley 14th February at am. Good morning Val, This is a tricky question to answer, as there can be numerous sources of damp and it is recommended to get a professional to inspect the chimney for damage.

Good morning Susan, The issue outlined does sounds like a damp issue, rather than a condensation problem.
Roxanne 5th April at pm. Condensation is unavoidable and happens when hot air hits a cold surface. If condensation is left to sit on surfaces for too long, it will cause damp and mould. Rising damp looks like a yellow watermark on your wall and often starts just above your skirting board, slowly expanding.
Because of the area it often appears in, it can cause your skirting boards to rot too. Rising damp happens when groundwater penetrates through the brick of your home and making its way to your interior walls. Penetrating damp is more common than rising damp and is caused by things like a burst pipe or water ingress.
It can often be a sign of exterior damage to walls or a roof. This kind of damp looks patchy and is often high up walls near the ceiling or down by skirting.
Mould is the most obvious sign of damp and is often the result if the damp has been present for a while. For earlier signs of damp, you might notice a musty smell or your walls could feel cold and wet. Another sign is discolouring or peeling of your paint or wallpaper. A PIV or positive input ventilation unit creates a positive air pressure in a house. What this does is push out old, stale and damp air to replace it with dry, clean air.
Costing just a few pennies a day to run, it can improve air quality and reduce condensation. There are many different possible causes for damp, but a couple of examples could include:. Rising damp — failed damp proof course allowing water to come up through brickwork and into internal areas of the house. Penetrating damp — cracked roof tile allow rainwater into the loft and causing damp.
This can be anything from adding a new liquid damp proof course to fixing the broken roof tile. The related symptoms of the damp will also need to be handled before painting is attempted. While damp proof paints are excellent products, simply painting over the problem without dealing with the underlying cause will usually mean the problem simply comes back. But how do you get help with damp? The answer is simple — you need to chat with damp proof experts who can carry out a survey of the house and find out what the problem is.
