Sikagard®-1814

• WRAS certified, certificate approval no. 2307541, RAL 7035, up to 50°C water temperature.
• Tested according to BS 6920 (conformity test for use in water up to 50°C)

Epoxy polysulfide resin

12 months from production date

Sikagard®-1814 shall be stored in dry conditions, where it is protected from direct sunlight and at temperatures between +5°C and +25°C.

~1.5 kg/l (mixed, at 25°C)

≥ 65

≥ 10 N/mm² (or substrate failure)

Sikagard®-1814 is resistant to the various typically encountered chemicals:

Gasoline, Diesel Fuel, Isopropanol, Sodium Chloride Saturated, Sodium Hydroxide 50 %, Ammonium Hydroxide 50 %, Nitric Acid 20 %, Sulphuric Acid 10 %, Hydrochloric Acid 5 %, Acetic Acid 10 %, Lactic Acid 10 %, Sea and brackish water, etc.

Note: Consult your local Sika office for project specific recommendations.

Beware of condensation!
The substrate must be at least 3°C above dew point to reduce the risk of condensation or blooming on the coating.
Note: Low temperatures and high humidity conditions increase the probability of blooming.

+10°C min. / +45°C max.

< 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM D 4263 (Polyethylene-sheet).

Times are approximate and will be affected by changes in ambient conditions, particularly temperature and relative humidity.

• As a guide: ~0.25 L/m²/coat, minimum two coats are recommended.
• Dry film thickness: 500 microns. Higher thickness shall be applied with multiple layers application.
• The full pack of 15 liters of Sikagard®-1814 will cover 30 m² theoretically at 0.5 mm thickness.

Note: These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variations in level and wastage, etc..

For application by airless spray, use a 45:1 or higher ratio pump, minimum 9mm dia. hoses and HD tip 19-23 thou.

All surfaces, concrete or metal shall be cleaned using high pressure water jetting, grit blasting or other methods approved by the engineer to
provide adequate mechanical key for excellent bonding as further indicated in the method statement. It is most important to ensure that thorough surface preparation is undertaken prior to application of the Sikagard®-1814 coating.

CONCRETE

• Ensure concrete is free from excessive laitance, grease, oil, curing compound, etc.
• Ensure concrete is sound, cutting back where necessary and making good using suitable SikaEmaco®, Sikadur® or Sikagard® repair systems.
• Ensure all blow holes and surface imperfections are made good prior to application of the Sikagard®-1814 coating.
• On a well-prepared surface Sikagard®-1814 can be applied without the use of primer, in case the concrete is porous, apply a primer coat using SikaEmaco® P 102 and allow it to get tack free prior to applying Sikagard®-1814.
• Ensure concrete is sound and at least 28 days old and the moisture content is less than 4%.
• Contamination by oil, grease, fats etc. must be removed before other forms of preparation begin.
• Remove laitance to expose blow holes, by light grit blasting or any other method as described in the method statement.

STEEL

• All previous surface treatments should be removed taking the surface back to base metal.
• The base metal should be abraded and preferably shot blasted with grit, steel shot or proprietary abrasive.
• Where shot blasting is impractical pre-treatment may be carried out with pneumatic de-scaling guns, tap hammers, rotary wire brushes or by flame scaling.
• Cleaning with solvent or a strong detergent is advisable to ensure surface is free from grease etc.
• Do not allow surface to re-oxidize before application of Sikagard®-1814.

OVERCOATING

• Where areas need to be overcoated due to damage etc. it is important that the areas to be treated are well abraded using a stiff rotary wire brush or coarse sandpaper to give an adequate mechanical key.
• Completely strip off any unsound coating and proceed with overcoating as for new work.

• Sikagard®-1814 is supplied in two pre-weighed components, base and reactor.
• No additions or omissions are required. Add reactor contents to the base component and mix thoroughly for using a slow speed drill fitted with a suitable mixing paddle until a uniform streak free color is achieved.

• Sikagard®-1814 coating can be applied using good quality rollers or short haired brushes or by airless spray.
• It is recommended that Sikagard®-1814 coating be applied in two coats of contrasting colors to ensure complete coverage.
• If the application is delayed more than 16 hours at 40°C or 36 hours at 20°C after the previous coat (the higher the ambient temperature, the shorter the maximum period), then the previous coat must be thoroughly abraded to give an adequate mechanical key and solvent wiped.
• For wholesome water applications, allow for min. 14 days prior to use.

Clean all tools and application equipment with suitable thinner (Xylene / MEK / Acetone) immediately after use. Hardened and/or cured material
can only be removed mechanically.
