How to Remove Algae from a Fence Before Painting
Before you begin painting your outdoor fence, you should prepare the surface by removing any biological growth such as algae, fungi and mould. Applying the paint over these contaminants will result in an uneven finish and may cause the paint to fall off.
Not only is biological growth harmful to your paint job, it is also harmful to the fence itself. Algae, fungi and mould can cause wooden fences to rot, reducing its lifespan and becoming a more costly issue as you may have to replace the fence.
Our product is designed to prepare the fence before the application of paint. Its formula removes all algae, fungi and mould and prevents it from returning, leaving you with a beautifully painted fence that is protected from contaminants.
How to Prepare your Fence for Painting
The best way to prepare your fence for painting is to use a specialist product that is designed to clean and sanitise the surface of your fence. Our GK Concentrated Fungicidal Wash acts as a “decorator’s mate”, making surfaces ready for paint application once dried.
GK Concentrated Fungicidal Wash is a unique product that has been formulated for cleaning and sanitising both external and internal hard surfaces prior to decoration. It is a broad spectrum surface biocide for professional use against fungal and algal growth on hard surfaces.
The product is self neutralising so it doesn’t require rinsing after application. Simply allow the dilution to evaporate and your fence will be ready for paint application once it has dried.
How to Apply GK Concentrated Fungicidal Wash
Surface Preparation: Remove dirt, grease, and loose coatings. Scrape off mosses, lichens, mould, or algae growth using a stiff brush.
Fungicidal Wash Dilution: Dilute 1 part GK Concentrated Fungicidal Wash with 4 parts water.
Fungicidal Wash Application: Apply the solution to the fence using a brush, roller, or spray in dry conditions.
Evaporation: Allow the solution to evaporate naturally for optimal effectiveness. No rinsing required.
Repeat Application: For heavily infected surfaces, a further application may be necessary.
Caution: Wear appropriate PPE, including protective gloves and eye/face protection, during application.
Can I Remove Algae from a Fence with a Household Solution?
You can use household bleach or white wine vinegar to remove the algae contaminants before painting, but this is not guaranteed to work effectively, nor will it provide any lasting protection.
These options are bleach and acid based so you have to be careful not to damage the surface of your fence. GK Concentrated Fungicidal Wash is bleach and acid free so it will not harm the fence in any way.
For the best results, and to tackle more stubborn biological growth we would always recommend using a specialist cleaning solution.
Preparing a Fence for Painting with Bleach
Mix 1 part bleach with 4 parts water. Apply this to the affected areas of your fence, leave it for 10 minutes then scrub the fence and rinse with water.
Preparing a Fence for Painting with Vinegar
Mix 1 part white wine vinegar with 4 parts water. Apply this to the affected areas of your fence with a spray bottle, leave it for 30 minutes then scrub the fence and rinse with water.
