The product must be stored in original, unopened and undamaged sealed packaging in cool and dry conditions, protect from direct sun light and frost. Always refer to packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Static crack-bridging (EN 1062-7:2004. Method A):

Dynamic crack bridging (EN 1062-7:2004. Method B):

All testing was carried out using Sikagard®-552 W Aquaprimer as a primer.

Minimum required dry film thickness to achieve the required characteristics (CO₂ equivalent air thickness of 50 m) ≈ 210 μm.

Substrate and ambient temperature must be at least 3 °C above dew point.

Waiting time between coats at +20 °C substrate temperature:

When the application is over existing coatings, the waiting time for both primers is doubled.

Maintenance coats of Sikagard®-5500 can be applied without priming if the existing coat has been thoroughly cleaned.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

EXPOSED CONCRETE WITHOUT EXISTING COATING

Preconditions

New concrete is at least 28 days old.

The substrate is clean, dry and free of all contaminants such as dirt, oil, grease, surface treatments and loose friable material which can reduce the adhesion of the coating.

1. Prepare the substrate mechanically using suitable equipment such as abrasive blast cleaning or high pressure water jetting to achieve a textured surface profile suitable for the Product thickness and required coating adhesion values.
2. Fill all surface defects, blowholes, cavities and pores using a pore filler (such as Sika MonoTop®-3020, SikaEmaco® N 5100 FC or Sikagard®-545 W Elastofill) to provide a defect free surface.
3. Leave the pore filler to cure for the appropriate time before the application of the primer coat. Refer to the individual product datasheet for further information.

EXPOSED CONCRETE WITH EXISTING COATING

1. Test existing coatings to confirm their adhesion to the substrate and their compatibility.

As guidance, in the absence of any national standards or regulations, adhesion test average ≥ 0.8 N/mm² with no single value below 0.5 N/mm².

INADEQUATE ADHESION

1. Completely remove existing coatings using suitable equipment and prepare the substrate as described in 'Exposed concrete without existing coating'.

ADEQUATE ADHESION

1. Thoroughly clean the existing fully bonded coating surfaces of all contaminants using suitable equipment such as steam cleaning or high pressure water jetting.
2. For a waterborne existing coating, use Sikagard®-552 W Aquaprimer as a primer.
3. For a solvent-based existing coating, use Sikagard®-551 S Elastic Primer as a primer.
4. If coating type is unknown, carry out compatibility and adhesion testing to determine which primer is most suitable.

IMPORTANT Wait at least 2 weeks before conducting the adhesion test. The adhesion test average must be ≥ 0.8 N/mm² with no single value below 0.5 N/mm²

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

IMPORTANT

Reduced product performance due to adverse climate conditions

Climate conditions during application and curing of the Product can affect the final performance achieved.

1. Do not apply the Product if rain is expected.
2. Allow enough time for the substrate to dry after rain or other inclement weather conditions.
3. Application during temperatures below the stated application temperatures may reduce adhesion values.

IMPORTANT

Damage due to permanent water contact

The Product is resistant to wet weather conditions but not suitable for permanent water contact.

1. Do not use the Product for applications with permanent water contact or immersion.
2. Do not use the Product for horizontal surfaces where water can pond.

Areas with low UV exposure

Note: The coating is a UV-curing acrylic dispersion. If applied in areas with low UV exposure, there is an increased risk of dirt pickup on the surface.

Shorter maintenance coating intervals for dark colour shades

Note: Dark colour shades, especially black, dark red and blue, may fade quicker than brighter colour shades. This effect is purely aesthetic and does not adversely influence the technical performance or durability of the Product. For aesthetic reasons, dark colour shades may require maintenance or refresher coatings at shorter intervals than usual.

PRIMER COAT

1. Apply by brush or roller, 1 coat of the appropriate primer at the required consumption rate, to all the surfaces requiring the Sikagard®-5500 coating.

PROTECTIVE COATING

1. Ensure the primer is thoroughly dry before over-coating to prevent the formation of bubbles and blisters, particularly in warmer weather.
2. The Product is supplied ready for use. Before application, mix using a low speed electrical single paddle mixer or other suitable equipment until a homogeneous consistency and colour is reached (depending on quantity 1-2 minutes).
3. Apply evenly by brush, roller or airless spray, 1-2 coats the Product to achieve the required total dry film thickness.
4. During application, regularly monitor the wet film thickness and material consumption to ensure the correct layer thickness is achieved.

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
