Technical specifications

Data verified in the official technical data sheet. Full technical documentation and certificates are available on request through the contact form.

Supports

Ceramic brick, cement block and renders in good condition. Substrates must be sound, strong and free of any substance or particle that could hinder adhesion. It is advisable to dampen the surfaces beforehand, especially in hot or windy weather. For substrates that are difficult to bond to, consult the Surface Guide.

How is ESTonetex Sulfo mixed?

Mix with clean water (24 to 26 % by weight, i.e. 6 to 6.5 litres per 25 kg bag), with an electric mixer or by hand, until a homogeneous, lump-free, workable paste is obtained. If application is mechanical (recommended), once the hose section and length have been chosen, the water/mortar ratio is adjusted by trial and error until the same consistency is reached.

How is it applied?

Apply in a single layer of 20 to 60 mm thickness, by hand or with a spraying machine. For thicknesses above 60 mm, apply the product in several layers and reinforce with fibreglass mesh. The surface treatment of the mortar (moulding and stamping) is carried out between 2 and 12 hours after application, depending on ambient conditions, applied thickness and type of surface. Once dry, it is pigmented and protected with a mineral water repellent.

Observations and precautions

Protect fresh mortar from frost and rapid setting: apply between 5 °C and 35 °C. Application in strong winds may cause cracking; if so, take protective measures. Contains cement: wear gloves, goggles and a mask. Professional product: always consult the safety data sheet.

Pigmentation

Once the mortar is dry, it can be pigmented with EST-26 Multilite, EST-Monocrom or EST-Multipol. When the work is finished, it is recommended to apply the EST-3 Plus mineral water repellent for added protection.

Complementary materials

•  Fibreglass mesh: reinforcement between layers for thicknesses above 60 mm

•  ESTonetex Forte: thin-layer mortar that, according to the catalogue, works as a primer for Sulfo on EPS/XPS and low-adhesion surfaces

•  EST-26 Multilite / EST-Monocrom / EST-Multipol: pigmentation of the finish once dry

•  EST-3 Plus: mineral water repellent to protect the finish

Frequently asked questions

Can ESTonetex Sulfo be used in swimming pools with chlorinated or salt water?
Yes. It is made with sulphate-resistant cement and a high level of water-repellent material for surfaces and places in contact with salt or chlorinated water, such as swimming pools, waterfalls, showers and fountains.

Is ESTonetex Sulfo suitable for aquariums or full immersion?
It is not the right product. Sulfo is designed for surfaces in contact with salt or chlorinated water (swimming pools, waterfalls, showers, fountains), not for full continuous immersion. For aquariums, submerged rocks and immersion areas, the specific product in the ESTonetex System is ESTonetex Extreme, which is mixed with EST-26 Multilite.

What is the difference between ESTonetex Sulfo, TXT and Park?
All three are used for theming by moulding and stamping. ESTonetex TXT and ESTonetex Park come in sandstone, white and grey, with layers of 10 to 70 mm and 10 to 50 mm respectively. Sulfo contains sulphate-resistant cement and a high level of water-repellent material for contact with salt or chlorinated water, is applied in layers of 20 to 60 mm and its colour is greyish ochre.

What thickness does ESTonetex Sulfo mortar allow?
From 20 to 60 mm in a single layer. For thicknesses above 60 mm it is applied in several layers, reinforced with fibreglass mesh, up to a total of 20 cm.

How much ESTonetex Sulfo mortar is needed per m²?
Approximately 14 kg/m² at 10 mm thickness, according to the technical data sheet. A 25 kg bag therefore covers about 1.8 m² at 10 mm, and the coverage decreases proportionally as the thickness increases.

How much water does ESTonetex Sulfo mortar need?
Between 24 and 26 % by weight, i.e. 6 to 6.5 litres per 25 kg bag. In mechanical application it is adjusted by trial and error until a homogeneous, lump-free, workable paste is obtained.

What temperature can ESTonetex Sulfo be applied at?
Between 5 °C and 35 °C. Fresh mortar must be protected from frost and rapid setting, and strong wind can cause cracking if no protective measures are taken.

When is ESTonetex Sulfo mortar moulded and stamped?
Between 2 and 12 hours after application, depending on ambient conditions, applied thickness and type of surface. Once dry, it is pigmented and protected with EST-3 Plus.

Is ESTonetex Sulfo mortar suitable for outdoor use and fire resistant?
It is suitable for decorative work both indoors and outdoors and has Euroclass A1 reaction to fire (non-combustible material), according to the technical data sheet.

How long can ESTonetex Sulfo mortar be stored?
Up to 24 months from the manufacturing date, provided it is kept in its original closed packaging, under cover and in a dry place.
