Igol® A - Bituminous emulsion for priming and waterproofing
Igol® A: anionic bituminous emulsion for priming and waterproofing
Igol® A is a water-based, unfilled anionic bituminous emulsion with high fluidity, used as a bituminous primer and for waterproofing walls and foundations. Its dry solids content of approximately 60% by weight forms a continuous black film with very low consumption: 0.600-0.800 kg/m² in two coats.
Being water-based, it contains no solvents, is non-flammable and can be cleaned with water while still fresh. It complies with UNE 104-231 type EA and DBI 2282, and can be applied on dry or slightly damp substrates.
✅ Main advantages
Water-based: solvent-free and non-flammable.
High fluidity: penetrates and covers well, even on rough substrates.
High yield: 0.600-0.800 kg/m² for both coats.
High dry solids content: ~60% by weight.
Versatility: works both as a primer and as a waterproofing coat.
On damp substrates: suitable for dry or slightly damp surfaces.
Economical: a cost-effective solution for buried walls.
🏗️ Recommended applications
Bituminous primer prior to asphalt membranes.
Waterproofing of vertical walls and buried foundations.
Protection of concrete surfaces against ground moisture.
Exterior face of basement walls and manholes.
Protection of buried metal and masonry elements.

🧰 Directions for use
Clean the substrate and remove grease, dust, oils, rust and any poorly adhered parts.
Fill voids, cracks and joints before priming.
Stir the product in the container until homogeneous; there is no need to dilute it.
Apply the first coat with a brush, scrubbing brush or roller, on a dry or slightly damp substrate.
Wait about 24 hours before applying the second coat.
Adjust the total consumption to 0.600-0.800 kg/m² across both coats.
Clean the tools with water while the product is still fresh.

💡 Professional tip: what ruins a water-based bituminous primer is rushing. The 24 hours between coats are not just a guideline: if you cover the first coat before the emulsion has broken, the water gets trapped and the film stays soft and sticky for weeks. Watch the shelf life too: Igol® A lasts 6 months, half as long as most products in the range, so don't stockpile it or leave it outdoors in winter, because a frost will break the emulsion inside the container.

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?
