How the EKOPEL Pouring Technique Works

See how you can resurface your bathtub in just a few hours using EKOPEL 2K Classic, Optimum, or Gold with the proven pouring technique.

The detailed process is demonstrated in the video. Please follow the link.

Frequently Asked Questions

All EKOPEL 2K materials are specially formulated for resurfacing old bathtubs and are applied using a casting process. They create a smooth, thick, and durable finish with excellent adhesion.

EKOPEL 2K Classic cures in approximately 48 hours and is particularly suitable for DIY enthusiasts due to its longer working time.

EKOPEL 2K Optimum cures in about 24 hours, making it ideal when the bathtub needs to be back in use sooner.

EKOPEL 2K Gold also cures in roughly 24 hours and provides enhanced UV protection. If your bathroom has a window or the bathtub is exposed to sunlight, we recommend EKOPEL 2K Gold.

EKOPEL 2K is applied using a pouring technique. The material flows evenly across the surface, creating an exceptionally thick, smooth, and glossy coating.

EKOPEL Roll-On is applied in two layers using a roller. It is especially suitable when the drain cannot be removed or when an easier application with a roller is preferred. Roll-On can also be used on wall and floor tiles.

EKOPEL 2K is suitable for steel, cast iron, ceramic, fibreglass, as well as previously coated bathtubs.

For acrylic bathtubs, use is only recommended if the walls are stable and not flexible. If the surface moves or gives way when pressed, we do not recommend using it.

For a standard bathtub up to 170 × 80 cm, you will need an EKOPEL 2K set with 2.4 L.

For larger bathtubs, we recommend an additional 1.2 L set.

For shower trays up to 90 × 90 cm, a 1.2 L set is usually sufficient. For larger shower areas, we recommend a 2.4 L set.

The EKOPEL 2K set already includes the main material and essential accessories.

In addition, you will need masking tape, protective film or paper for the floor, a hairdryer or heat gun, a container with a capacity of around 400–500 ml, tools for removing or opening the drain, a knife or cutter, cleaning cloths, and a solvent for cleaning your tools.

We also recommend wearing clothing that can get dirty.

Before application, thoroughly clean the bathroom. Remove dust from shelves, walls, ceilings, and surfaces to prevent any particles from settling on the new coating.

Take out towels, personal care products, and loose items from the bathroom. Keep windows closed during application to avoid dust or insects settling on the surface.

The room temperature should be at least +20 °C starting the day before application and throughout the curing process.

The bathtub must be clean, dry, free of grease, and free of silicone, limescale, rust, and loose old coating.

All silicone residues must be completely removed, as the coating will not reliably adhere to them. Limescale deposits, rust spots, and loose old coatings must also be removed.

Deep damage, grooves, or chipped areas over 1 mm should be filled with epoxy or polyester filler before coating and then sanded smooth.

Pour the entire Component B into the bucket containing Component A. Thoroughly mix the material using the supplied wooden stick.

Stir carefully for about 10 minutes to ensure no unmixed residue remains on the bottom or sides. Then allow the mixture to rest for approximately 5 minutes before stirring again for about 5 minutes.

After this, the material is ready for application.

EKOPEL 2K is not applied with a roller or brush, but poured.

Use a cup with a capacity of about 400-500 ml and pour the material evenly along the edges and walls of the bathtub. The material flows slowly downwards, spreading across the surface.

This pouring method creates an exceptionally smooth, thick-layer coating with a glossy finish.

Whenever possible, we recommend removing the drain or at least covering the drain opening. This allows any excess material to drain away cleanly.

If the drain cannot be removed, the drain opening must be carefully sealed. Cover the opening with paper, secure it firmly with masking tape, and then carefully cut the tape along the edge.

The overflow should also be removed or carefully masked off.

The room temperature should be at least +20°C. This temperature should be maintained one day before application, during processing, and throughout the curing period.

For easier application, we recommend warming Component A to around +30 °C before use. To do this, place the bucket in warm water or store it in a warm location a day in advance.

Temperatures that are too low can impair flow properties and significantly prolong curing time.

At room temperature of around +24 °C, the bathtub can be carefully used again after approximately 24 to 48 hours, depending on the product. At around +21 °C, we recommend waiting 2-3 days before using the bathtub. Curing may take longer at lower temperatures. Bottles, soap containers, pets, and products containing dyes such as hair colour or coloured bath additives should only be introduced after about 7-14 days.

Small dust particles, insects, droplets, or surface imperfections can be carefully addressed after curing.

Minor unevenness can be smoothed with fine sandpaper and then polished using polishing paste. For small scratches or damaged areas, we recommend a repair kit.

Deeper damage should be repaired as soon as possible to prevent water from penetrating beneath the coating.

Use mild bathroom cleaners without harsh abrasives. Cleaners with a gentle acidic base are generally suitable.

Avoid stiff brushes, abrasive sponges, and highly abrasive cleaning agents. Residues from hair dye, coloured bath additives, or cosmetic products should be removed immediately.

Proper care significantly extends the lifespan of the coating.

EKOPEL 2K is virtually odourless and contains no strong-smelling solvents. Any smell is minimal and dissipates quickly.

The material has been tested according to DIN EN 71-3. Nevertheless, we recommend using standard protective equipment such as gloves, safety glasses, and ensuring good ventilation during application.

Avoid contact with skin and eyes.

Cured material can generally be disposed of with regular household waste. Uncured material residues should be treated as hazardous waste.

Liquid leftovers can be mixed together and disposed of after they have fully cured.

Store the material in a dry place, tightly sealed, and at temperatures between +5 and +35 °C. The shelf life is 2 years from the production date.

The material has a shelf life of 2 years from the production date when stored in a dry, tightly sealed condition at temperatures between +5 and +35 °C. Within this period, the product can be used.

The lifespan of the new coating can last many years with proper surface preparation, correct application, and normal maintenance.

The actual durability largely depends on the surface preparation, application process, cleaning, and everyday use.

Yes, EKOPEL 2K can be tinted using the appropriate EKOPEL colour pastes.

The colour is added to Component A before mixing in Component B. The required amount depends on the respective colour chart.

Alternatively, pre-tinted variants can be used if available.
