Well, it is important to determine whether the mould is only on the surface or if it has spread to deeper layers of the wall. If the latter is the case, as a result of water continuously penetrating the wall due to water damage or a lack of draining, the plaster needs to be removed generously.

There’s two options you can go with here, you can simply clean down the mould area affected with mould and mildew cleaner and paint over with mould paint. This of course would be the most budget friendly option, but there always runs the risk of the mould returning. Instead we could remove the plasterboard, install storm dry on the block work and replace the plasterboards. This option would mean it’s less likely for the mould to return, but it’s up to the customer. Both jobs would be finished professionally and will remove the mould from the affected area.

using bleach or even a mould wash will only remove the surface mould. The main issue is active mould growing throughout the plasterboard. Unfortunately, the only way to get rid of mould for good is to replace the plasterboard.

It's essential to address the moisture issue first to prevent further mold growth. Once the repairs are completed externally, you can remove the mold using a mixture of water and detergent or a specialized mold cleaner. Afterward, apply an anti-mold primer or paint to inhibit future growth. Products like Zinsser Mold Killing Primer or Dulux Anti-Mould Paint are popular choices. Ensure proper ventilation in the room to reduce moisture buildup. If the mold infestation is severe, consulting a professional might be wise.

We would remove the mould first and then apply Anti mould or Damp proof paint over the area where mould persist.

Hi there .
I have read your question and my advice would be to remove the plaster and start again with fresh plaster .. it would be a bit more expensive to do but as you are already repairing the guttering and the fascia . . The wall itself would be hard to judge at how far the water has penetrated the wall .. you can use anti mould paint ..but! That would only help the top surface not inside the wall ,, that is why re plastering would be the best .

remove the mould and add an anti mould paint i’d recommend using zinsser perma white mould resistant paint

Certainly, if the mould growth is limited to a small area, you can remove it and apply anti-mould paint over it. Make sure to address the underlying cause of moisture to prevent future mould growth. Look for anti-mould paint products at your local hardware store.

If you've found black mold in your front bedroom due to water ingress from exterior issues like faulty guttering, it's crucial to tackle both the mold and the underlying moisture problem. Begin by thoroughly removing the mold using a mixture of water and detergent or a commercial mold cleaner. Protective gear like gloves and a mask is essential during this process. Once the area is clean and dry, address the exterior issues causing moisture intrusion, such as repairing the guttering and fascia. After ensuring the wall is completely dry, apply an anti-mold paint or primer to inhibit future mold growth. Be sure to choose a product specifically formulated for this purpose and follow the manufacturer's instructions carefully. Regularly monitor the area for any signs of mold recurrence and promptly address any new issues that arise.

Certainly! Dealing with black mold on walls can be a common issue, especially in areas with moisture or poor ventilation. Let’s break down the steps to address this situation:

Removing the Mold:
Before applying any paint, it’s essential to remove the existing mold. You can choose from two methods:

Method 1 (Quick Wash):
Prepare the area by laying down dust sheets and covering nearby furniture.
Mix warm water with a few squirts of washing up liquid.
Use a kitchen sponge or scourer to wipe off the surface mold.
Rinse the wall with clean water and wipe it dry with kitchen roll.

Method 2 (Baking Soda Paste):
Prepare the area and cleaning solution.
Mix two parts baking soda with one part white vinegar to create a thick paste.
Apply the paste to the mold-affected area and leave it for about an hour.
Use a stiff brush to remove as much of the paste as possible.
Wipe down the area with a damp cloth and clean up any debris1.

Anti-Mold Paint:

Once you’ve removed the mold, consider using anti-mold paint to prevent its recurrence. Here are some options:

Suretherm Anti-Condensation Paint:
This water-based emulsion is designed to deal with internal mold caused by condensation. It absorbs heat that would otherwise escape through the wall, thanks to its glass microsphere technology.

Polycell One Coat Damp Seal and Zinsser Perma White Mould Resistant Paint are also good choices. They resist moisture, steam, and deter mold growth2.

Dulux Trade Mouldshield Fungicidal Matt is another option for indoor walls and ceilings affected by mold or damp. It contains antifungal chemicals to keep mold at bay3.

If you have new or porous plaster surfaces, consider using Dryzone System Mould-Resistant Emulsion Paint thinned with water as normal practice4.

Remember to address the root cause of moisture (such as improving ventilation) to prevent mold from returning. Good luck with your bedroom renovation! ????????????

I would remove blown plaster and the unibond and re skim then damp and mold seal then finish

Do we need to remove all the plaster or can we remove the mould and apply anti mould paint over it?
- Everting is depended of client budget and intention

You don't need to remove the plaster you only need anti mould paint, I reckon you get Ronseal anti mould paint

we don't have to take down the plaster, the gutters have to be installed back and when we make sure that everything is ok, the wall has to be left until uncared, after which we remove the mold and after the painting process

depends how bad is it look... if the plaster is wet and crumbling better is remove it from wall but you can try wash mould and after drying wall with any heater if look alright after this paint with zinsser shelack bin primer 2 coats and after you ready for any filling or painting. If plaster need to remove you can use after one coat plaster british gypsum up to 13 mm deep if is more you need hardwall and multifinish after depends how big area... small area can use joint skim filler toupret after hardwall. Any plaster need to leave for dry longer :)

Using an anti mould paint would be the way to go but I’d wait until external works are done first then you can treat the wall on interior as if you paint the bedroom wall without fixing the outside you will have an ongoing problem the paint is use is zinsser perma white anti mould is the one I’d use if you have magnolia wall then use that one instead.

First you need to check if plaster and render has blown..in stall a dehumidifier to remove a lot of the built up moisture from wall.i would then suggest to clean arwa with bleach and water..if all is then fine and there is no need to replace plaster and render.then add a miss coat of diluted paint then apply.a.srain block such as zinnser B-I-N multi surface stain block and surface primer..but there are many different brands available. But black mould normally is a sign of poor ventilation.

You can remove only the mould treated with oil based or mould resistant paint . Need to follow rules how it say on the tin of the paint to leave to dry couple of hours and paint whatever paint you want to put on the corner of the ceiling.

Once a property has been treated with a damp-proof course, the next step is replastering. This process involves applying a new layer of plaster to the treated walls to provide a clean, fresh surface that can be decorated. It’s vital to use the right type of plaster after damp proofing to ensure the walls can dry out effectively. The plaster needs to be able to cope with any residual moisture and soluble salts in the brickwork. It’s essential that the application is carried out carefully and professionally too, so it provides a smooth durable finish.

If its dry yes wash the mould off with anti fungal wash then seal with stain block then paint over

I would recommend using Ronseal for that is a great product but I would also recommend getting the mould off as you can use anti-mould sprays which you can find in most supermarkets such as Tesco’s Sainsbury’s et cetera spraying on for half an hour then wiping it off with a cloth or sponge and then applying the paint using two coats and then using the top layer to finish off

The presence of mold in the corner of a bedroom wall can be concerning as it indicates a moisture-related problem that needs to be addressed promptly. Mold growth is often a result of excess moisture and poor ventilation, creating an environment conducive to mold spores’ development and proliferation.

Addressing the presence of mold in the bedroom corner requires a comprehensive approach that involves identifying and rectifying underlying causes such as condensation, poor ventilation, and insulation issues. By implementing strategies to reduce moisture levels, enhance airflow, and improve insulation, you can effectively combat mold growth and maintain a healthy indoor environment.

Yes you can remove the mould and use anti mould paint over it .
Thank you.

You have to look at the type of the wall and remove pretty much everything that is damaged but for knowing an answer more specific someone should give a look to get an answer about your concerns

The mould could be caused by a few things condensation. The gutters outside leaking no windows open I would wash with anti mould spray if plaster is loose then take it back to brick and wait for it to dry out then replaster if not loose apply two coats of anti mould paint but if you don’t open windows or get gutters fixed it will just keep coming back

We do remove the mould and apply anti mould paint over it,and recommend from Deluxe brand.

Check how damaged is the plasterboard ,you said you know the cause, I would start with fixing the gutter first as the winter is almost here, wipe the mould of the wall ,allow it to dry properly then apply 2-3 coats of Zinsser Bin Shellac, fill whatever needs filling ,sand and after you can apply the emulsion paint
