Increase Airflow Under Your House | Rising Damp | Soft Brick Repair

Noticing the presence of mold/ fungus on your walls inside your house, dampness on your cornices and floor coverings such as rugs or carpet? Odds are, whether you are living in an older house or not, if the dampness is located down the bottom of your internal walls or on your floor/ coverings, you are experiencing the effects of rising damp. 

No amount of  additional air movement inside your house will prevent and minimise the effects of rising damp.

From the ground up, you will need to repair soft brick which hold additional moisture, replace and reinstate any defective, soft or missing mortar in between the brick and install a permanent barrier to lower the effects of water rising up the wall and into your floorboards and internal plaster wall linings.

Also, increasing airflow under your house will help to prevent excess amounts of moisture and the consequences encountered. Subfloor ventilation in the way of ‘passive’ air vents or ‘active’ motorised fans can help keep the air moving.

The above photo indicates the process of removing soft brick that is a so commonly experienced from rising damp.

Whilst repointing will help to prevent water ingress into the wall and internal cavity, without replacing soft brick, your wall will still be harbouring moisture. The only way to remove this issue, is to replace the brick. Rendering soft brick can sometimes have a detrimental effect as the mortar used to patch the brick can also harbour moisture if not installed properly.

What are Lichens? Lichen Removal Melbourne | VICRestorations.com

Want to clean lichen from your roof tiles, brick or stone walls? There are several methods which you can use to help remove the unsightly outbreaks.

The Dry Scrape

By taking the time to remove lichen this way, you can also improve the surface of the stone, tile, brick, or block that is harboring it. Lichen are a mixture of fungus and mould, created by spores and moisture. They can harbor moisture helping to breakdown the stone or masonry surface underneath.

By taking a dull object such as a straight piece of softwood, you can physically dislodge the lichen from the surface of the substrate. The following video shows the movement albeit has a chisel being dragged instead of a piece of timber. The stone in this case was also bluestone which isn’t easily marked. Caution should always be used with soft stone such as slate, marble, sandstone and limestone.

If you have an ornate statue or architectural feature such as an intricate carving, you will want to use other methods in conjunction with a very soft, dry scrape.

Wrapping a statue up in cling wrap for 3-4 days will help to soften dirt, mould and fungus that may have hardened. After the pollutants have softened, remove the ‘poultice’ and commence using a soft dry scrape method as shown above.

Biocides

Spraying chemicals has its appeal but it also has it’s drawbacks. If not diluted or used properly the typical ammonium-based sprays can cause damage or not work at all.

Wet and Forget

Use a garden sprayer to thoroughly saturate the lichen with a solution of 1 part Wet & Forget Outdoor and 5 parts water. Wait 15 minutes, and spray a second time. This will allow the Wet & Forget Outdoor to penetrate the lichen’s 2 layers. It is best to spray lichen on a day that is not too sunny, to prevent rapid evaporation and to allow Wet & Forget more time to work.  Read more…
