🚨Mould is a fungus that acts as a decomposer, breaking down materials to digest them as food.
Enzymatic Degradation:
Mould releases enzymes that break down organic materials, such as wood, paper, and adhesive substances, causing structural damage and rot.
Root Pe*******on:
Mould grows a network of thread-like roots called mycelium that pe*****te porous surfaces, breaking them down from within.
Acid Secretion:
Certain types of mold can release weak acids that erode concrete, masonry, and other building materials
🚨Algae are plants that thrive on moisture and light, acting as a "base layer" for further damage.
Moisture Retention:
Algae holds moisture against surfaces, which accelerates the decay of paint and wood, leading to swelling, cracking, and rot.
Surface Staining:
Algae creates a biofilm that can deeply stain materials, breaking down the integrity of protective sealants and coatings.
Surface Damage:
On materials like wood, algae can accelerate erosion, while on concrete, it creates a weak, slippery surface that allows moisture to seep in, causing further structural deterioration.
Commonly Affected Surfaces🔍
Timber/Wood: Rot and deterioration, especially on decks and fences.
Paint/Render: Discoloration and breakdown of protective coatings.
Concrete & Brick: Increased porosity and weakening due to trapped moisture and algae rooting.
Roofs: Algae can damage shingles and cause it to fail prematurely.
Treatment/Prevention 💦
Pressure washing treats mould and algae by using high-pressure water to physically dislodge and wash away biological growth, dirt, and spores from hard surfaces like concrete, brick, and pavers. It acts as a deep-cleaning method that breaks the bond between organic growth and the surface, often requiring no chemicals, or using detergents to kill remaining spores.
