Preparing Surfaces for Sikagard Application

When preparing surfaces for Sikagard application, it's crucial to ensure that the surface is properly cleaned and prepped. Depending on the condition of the wood, several important steps must be followed for optimal results.

1. Cleaning the Surface: Thoroughly clean the surface using abrasive sanders, steam cleaners, or pressure washers to remove any dirt, oil, grease, or debris. This is essential to remove contaminants that could hinder adhesion.
2. Assessing Existing Coatings: If the surface already has a coating, ensure that it is well-adhered and clean. Sand down any flaky or peeling paint to create a solid base for the Sikagard treatment. This ensures that the new coating bonds well with the existing surface.
3. Dealing with Hydrophobic Treatments: For surfaces with a hydrophobic (water-repellent) treatment, prepare the surface for Sikagard application using steam cleaning, blast cleaning, or high-pressure water jetting. This step helps in removing any water-repellent barriers that could interfere with the Sikagard's adhesion.
4. Drying the Surface: Allow the surface to dry completely before applying the Sikagard product. Moisture can significantly affect the coating's performance, so it's important to ensure the surface is dry.

By following these preparatory steps, you can ensure that the Sikagard treatment adheres well to the wood surface. This results in excellent performance and makes it an ideal choice for your DIY wood care projects.

Applying Sikagard to Uncoated Wood Surfaces

Getting your wood ready for Sikagard is key for lasting protection and a top-notch finish. Follow these steps for great results in your DIY wood projects.

Priming Uncoated Wood with Sikagard

While Sikagard®-850 AG does not require priming when applied to wood (both coated and uncoated), if you are using a Sikagard product that specifies priming, follow these steps:

• Mix the Sikagard primer with about 50% white spirit.
• Spread it over the wood with a brush or roller, making sure it covers evenly without gaps.
• The Sikagard®-850 Primer usually needs 75 g/m² to 125 g/m².

Applying the Topcoat of Sikagard

After ensuring the surface is prepared (with or without primer, depending on product requirements), it's time to apply the Sikagard topcoat.

• Mix the topcoat with about 20% white spirit. You can also add colouring if you like.
• Spread it over the wood with a brush, roller, or spray, making sure it's smooth and even.
• The Sikagard topcoat takes 150 to 250 g/m² to cover. It forms a dry film of 150 to 300 µm.

By carefully priming (if necessary) and applying Sikagard, you can make uncoated wood look great and last long. Always check the local product sheet for any special instructions or rules in your area.

Treating Coated Wood Surfaces with Sikagard

For wood surfaces with an existing coating, use the Sikagard Activator as a primer before applying the Sikagard topcoat. This ensures the new Sikagard sticks well and works well with the old coating.

Here's how to treat coated wood surfaces with Sikagard:

1. Clean the Surface Well: Remove any old or flaking paint or varnish. This ensures the Sikagard Activator adheres properly.
2. Apply the Sikagard Activator: Use a brush or roller to apply the Sikagard Activator evenly over the prepared surface. Ensure the primer covers everything without gaps.
3. Let the Sikagard Activator Dry: Allow the Sikagard Activator to dry completely before applying the Sikagard topcoat. Depending on the weather, this usually takes 2-4 hours.
4. Apply the Sikagard Topcoat: After the primer is dry, follow the instructions to apply the Sikagard Topcoat. This will give your coated wood strong, lasting protection.

Always check if the Sikagard system works well with your wood's coating. This ensures it adheres and performs as expected, preventing problems later and providing the best results for your wood care project​.

For a full list of products and their features, you can refer to the table below to find out more about each and how they can help.

Using Sikagard on Substrates with Hydrophobic Impregnation

If your wood surfaces have a hydrophobic (water-repellent) treatment, you can add Sikagard for extra protection. First, prime the surface. Then, apply a top coat to make a solid, non-porous layer.

Priming:

1. Mixing the Primer: Mix Sikagard with about 50% white spirit.
2. Application: Spread the diluted primer over the wood evenly with a brush or roller, making sure the primer covers the surface without gaps.

Top Coating:

1. Mixing the Topcoat: Use Sikagard diluted with around 20% white spirit for the topcoat.
2. Application: Ensure the topcoat is smooth and gap-free. Apply it using a brush, roller, or spray.
3. Drying: Keep the new coating dry until it's fully cured to avoid damage from rain.

This method helps you apply Sikagard on wood with a hydrophobic treatment, providing a strong and protective finish. Always read the product's instructions and technical sheets for the latest advice on how to use it.

Sikagard products like Sikagard®-700 S are specifically designed for use on substrates with hydrophobic impregnation. These products penetrate well into the substrate's pores, providing durable water repellency while allowing water vapour to diffuse in both directions, ensuring the treated surface remains breathable​.

By following these guidelines, you ensure the optimal performance and longevity of Sikagard on hydrophobic substrates.

It's important to allow proper drying and curing to ensure the coating's longevity and effectiveness. Rushing this process can compromise the coating's durability.

Following the manufacturer's guidelines closely will help you maximise the benefits of Sikagard products and ensure your wood remains protected for a long time​.

Removal of Graffiti from Sikagard Treated Surfaces

Cold Water Pressure Cleaning Techniques

Sikagard offers robust anti-graffiti coatings that allow for easy graffiti removal without damaging the surface. The coatings are designed to withstand multiple cleaning cycles, typically allowing graffiti to be removed up to 20 times without requiring a new application.

To remove graffiti from Sikagard-treated surfaces, follow these steps:

1. Cold Water High-Pressure Cleaning: Use cold-water high-pressure jetting/cleaning equipment with a pressure of about 80 to 100 bar (1200 to 1500 psi). Maintain a distance of 10 cm from the surface during cleaning.
2. Avoid Rotating Nozzles: Do not use rotating nozzles, as they can damage the coating.
3. Low-Pressure Washing: For less stubborn graffiti, low-pressure cold-water washing combined with scrubbing using a clean cloth or brush can be effective.

These methods ensure the coating remains intact and effective, maintaining its protective qualities over time. By following proper cleaning techniques, your Sikagard surfaces will stay in excellent condition for many years.

Safety Precautions When Using Sikagard

Working with Sikagard requires following key safety steps to protect yourself and your surroundings. Sikagard is mainly for industrial and commercial use, so wearing personal protective equipment (PPE) is a must.

• Avoid Aerosol Applications: To prevent harmful vapours from spreading, avoid using Sikagard for aerosol applications. Instead, use brush, roller, or controlled spray methods. This keeps you and the area safe.
• Ensure Ventilation: Make sure the area is well-ventilated when applying Sikagard. This is because the product can release harmful vapours.
• Proper Disposal: Safely dispose of any leftover Sikagard or containers, following local environmental laws. Never pour it into water or sewers.
