How to Clean and Prepare Walls for Resin Application

Q: Step-by-Step Cleaning and Preparation

Clear the area: Remove any loose paint, wallpaper, old adhesive or debris with a scraper or stiff brush. Degrease: Clean the wall with acetone or alcohol, especially in kitchens or bathrooms, to remove oils and residues. Repair: Fill in cracks or holes with filler and sand smooth once dry. Uneven or rough patches should be lightly sanded to a uniform, slightly matt surface. Dust off: Wipe away all dust using a clean, dry cloth — even small particles can affect the clarity and adhesion of the resin. Prime (if needed): For porous or highly absorbent substrates, consider a suitable primer before your resin application. This creates an even base and can help with adhesion. Once prepped, your wall is ready for its Vertical Glass - Thick Resin Decorative Wall Coating or your chosen resin product.

Clean and Prepare the Wall Surface Thoroughly

Getting your wall perfectly clean and prepped is the foundation for any successful resin application. Proper preparation not only helps your resin adhere but also ensures a smooth, lasting result.

Why Surface Preparation Matters

Dust, grease, uneven patches, or any leftover coatings will all undermine the bond between your wall and the resin. Tidy, stable surfaces help prevent discolouration, peeling, and patchy finishes over time. Whether you’re aiming for a glossy decorative effect or a subtle protective coating, careful preparation means your project starts right.

When This Matters Most

Meticulous cleaning and prep are especially important if you’re working with glossy or transparent finishes, intricate 3D reliefs, or on surfaces in high-moisture areas. Good preparation is the easiest way to get professional-looking, long-lasting results in these situations.
