Proper preparation is crucial when applying resin to your terrace. A sound, clean foundation ensures your new resin surface will be both attractive and long-lasting. Here’s what you need to know before you begin your project.
Assess and Repair the Base
Begin by checking your terrace’s existing surface. Whether you have concrete, screed, or old tiles, make sure the base is free from movement and structural weakness. Fill any cracks, replace broken tiles, and address uneven spots with suitable levelling compounds. If your terrace collects water in puddles, improve drainage now to prevent future issues under the resin layer.


Thorough Cleaning and Drying
Remove all traces of dirt, algae, moss, and dust with a stiff brush or pressure washer. Any lingering debris or contaminants can affect resin adhesion. Allow the surface to dry completely—resin does not adhere well to damp bases and lingering moisture can lead to delamination. For concrete terraces, consider using a surface sealer like Resinstone Methacrylic Resin to improve durability and provide a better bond for your resin layer.
When This Matters Most
Taking the time to properly prepare your terrace is especially important before using systems such as the Flowstone Complete Permeable Floor Kit. A well-prepared, dry, and solid base ensures the resin-bound system performs at its best, whether you’re resurfacing a patio, balcony, or outdoor walkway.
