Finishing a floor with two-component epoxy putty creates a seamless, robust, and attractive surface ideal for both residential and commercial spaces. Whether you are renovating an old surface or installing a new one, this technique delivers outstanding resistance to daily wear, chemical exposure, and moisture, while offering a modern aesthetic. This guide will walk you through the essential steps to achieve a professional-quality epoxy putty floor finish.

What You’ll Need

"Epoxyprimer" - Universal Water-Based Two-Component Epoxy Floor Primer

Before You Begin: Understanding Epoxy Putty Application

Epoxy putty delivers a highly durable, seamless floor when applied correctly. Preparation and patience are the keys to flawless results. Wear gloves and eye protection as standard, and always allow ample curing time between layers.

Step 1: Prepare and Clean the Surface

Begin by ensuring your floor surface is solid, dry, and free from contaminants such as dust, oil, and loose debris. Use a vacuum or a soft broom to thoroughly remove all particles, paying particular attention to corners and cracks. If there are old coatings or flaking material, strip these away to expose a stable substrate. Proper substrate preparation is vital for long-lasting adhesion. For concrete, tiles, or timber, check that the surface is structurally sound before proceeding to the next step.

Step 2: Prime the Floor

Achieving optimal bonding and durability starts with using a high-quality primer. Apply “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer evenly across the prepared surface using a roller or brush. Work in manageable sections to avoid missing any areas, and ensure the primer penetrates any pores for maximum effectiveness. Allow the primer to cure for 24–48 hours, or according to the product instructions. Priming will seal and stabilise the substrate, preventing future delamination or bubbling.

Step 3: Mix and Apply Two-Component Epoxy Putty

Once the primer has fully cured, it is time to prepare your epoxy putty. Carefully measure and mix the two components of the “Magelstick” – Epoxy Mastic for Stone, Metal, and Cement Bonding and Grouting as per the recommended ratio (typically 100:50 by weight), ensuring a thorough blend for consistent performance. Use a spatula or trowel to apply the mastic onto the floor, beginning with deeper holes or cracks before covering the entire surface. Spread the putty evenly, working in sections and levelling as you go to achieve a uniform thickness. Remove excess material to maintain a flat finish. Allow each layer to fully cure before proceeding, and if necessary, sand down any imperfections before applying additional coats for levelling.

Step 4: Finishing and Polishing

After the epoxy putty layer is fully cured (refer to the product’s recommended curing time), inspect the floor for minor surface irregularities. Lightly sand as needed to smooth out the surface, then vacuum to remove dust. For a brilliant, glossy finish, use “Epoxy Polish” – Epoxy Resin Polishing System along with a polishing pad or rotary tool. Polish in circular motions to reveal the epoxy’s sheen and enhance durability, particularly in high-traffic zones. This last step is optional for floors where a satin or matte look is preferred.
