Epoxy mortar delivers a robust bond that resists cracking, staining, and damage, enduring heavy traffic, moisture, UV, and chemicals—ideal for long‑lasting outdoor tile.

Eco-friendly epoxy outdoor mortar uses low-impact materials and contains no harmful chemicals, solvents, or VOCs.

Epoxy mortar’s low water absorption protects outdoor tiles from moisture, preventing mold and damage and extending lifespan.

Epoxy mortar resists dirt and stains, cleans easily, and keeps high‑traffic outdoor tiles looking fresh for years.
Here is a complete guide for everything you need to know about applying your epoxy mortar. We understand that installing tile can seem like a complicated process, but if you have any questions, don’t hesitate to contact us, and we will be glad to help.
Ensure a stable, load‑bearing base with a water‑permeable sub‑base sized for traffic loads. VDW grouting suits small to large formats, but not substructure settlement, sealing, or waterproofing. 815 Grouting Binder can be applied on damp surfaces, in high humidity, and even in rain. Clean the paving thoroughly, clear joints to the required depth, pre‑wet the surface, and mask areas not being jointed.
Immediately pour mixed VDW 815 onto the pre‑wetted surface and squeegee into joints. If it hardens too fast, lightly spray with water. Keep the area constantly wet. Do not mix partial units or use unmixed material.
After 5 minutes, remove excess VDW 815 with a damp coconut fiber brush. Lightly spray the joints without washing out material, then clean the paved surface in the areas to be joined. Do not let residue‑laden water stand, dry, or run over finished sections. Finish by rinsing and brushing off any remaining residue with water and a coconut brush.
Avoid walking on freshly applied areas for at least 24 hours or until the paving surface is no longer tacky. A very thin layer of resin binder may remain on rough surfaces that are not thoroughly cleaned, but it will disappear over time as it is exposed to the elements.
