Sikagard®-711ES - Colorless water repellent for facades and roofs
Sikagard®-711ES: colorless water-repellent impregnation for facades and roofs
Sikagard®-711ES is a one-component, silane/siloxane-based water-repellent treatment that penetrates the pores of the substrate and makes it water repellent without forming a film or altering its appearance. It also incorporates self-protecting agents that delay the appearance of moss, algae and lichens for a minimum of 3 years.
Because it does not close the pores, the surface remains breathable: rainwater runs off, but water vapor from inside can escape. It is classified as a water-repellent impregnation for the surface protection of concrete according to UNE-EN 1504-2 and can be repainted with Sikagard®-670 W ElastoColor or Sikagard®-550 ES ElastoColor.
✅ Main advantages
Biological self-protection: delays the appearance of moss, algae and lichens for a minimum of 3 years.
Breathable: water-repellent effect while preserving the porosity and vapor permeability of the substrate.
Invisible: colorless liquid that does not change the appearance or color of the material.
Less dirt: reduces the penetration of dust and pollutants into the pores.
Repaintable: accepts Sikagard® polymer paints after 5 hours.
Proven performance: 200-250 g/m² on mortar or concrete.
🏗️ Recommended applications
Water-repellent protection of concrete, mortar, brick and stone facades.
Roofs and surfaces exposed to rain and ambient humidity.
Exposed brickwork and masonry walls.
Fiber cement and precast concrete elements.
Pretreatment for Sikagard® ElastoColor paint systems.

🧰 Directions for use
Check that the substrate is sound, clean and dry, free of dust, grease, efflorescence and old paint.
Repair cracks and open joints beforehand: the water repellent does not bridge cracks.
Apply the product as supplied, undiluted, with a brush, roller or low-pressure sprayer.
Work from the bottom up and wet on wet until the pores are saturated, avoiding runs.
Apply a second coat if the substrate is highly absorbent, respecting the indicated consumption.
Protect the surface from rain during the initial drying.
Clean tools and equipment immediately after use.

💡 Professional tip: the most common mistake is applying water repellent to a facade that still has water inside: the silane makes the pores repellent on the outside and slows down the drying of the wall. Wait at least 48 hours of dry weather after the last rain. And watch out for cracks: if they exceed 0.3 mm they must be sealed beforehand, because 711ES repels water but does not bridge cracks. If you also want color, use it as a base and finish with Sikagard®-550 ES ElastoColor after 5 hours.

Frequently asked questions about Sika products (mortars, adhesives and sealants)
How do I know which size and quantity to buy?
Each product page includes the approximate yield or consumption (for example kg/m² or metres of bead per cartridge) in the "Technical specifications" section. Calculate the surface area or thickness of your project and multiply by that consumption to find out how many units you need. If in doubt, contact us with the measurements of your job.
Where can I find the complete technical data sheet (Product Data Sheet)?
The description of each product already includes the main technical data (strengths, setting times, application temperature, applicable standards, etc.), taken from the official Sika Spain Product Data Sheet. If you need the complete PDF data sheet or the safety data sheet (SDS), write to us and we will send it to you.
Do these products comply with European regulations (CE marking)?
Most Sika products carry the CE marking in accordance with the relevant European standard (for example EN 1504 for structural repair, EN 12004 for tile adhesives, EN 13888 for grouts or EN 15651 for sealants). The exact standard for each reference is detailed in the "Standards and certificates" section of its product page.
What protective equipment do I need to apply them?
It depends on the product: cement-based mortars and adhesives are usually irritating to skin and eyes (gloves, goggles and a mask are recommended), while polyurethane sealants and adhesives require good ventilation. Always check the safety section of the product page and its safety data sheet (SDS) before use.
How should I store these products and how long do they last unopened?
Shelf life and storage conditions (temperature, humidity, protection from light) vary depending on the type of product (cementitious, polyurethane, epoxy, etc.) and are stated on the packaging and in the data sheet of each reference. In general, it is advisable to store in a dry place, protected from frost and direct sunlight.
Can I return a Sika product if I haven't used it?
