PRODUCT DATA SHEET

Sikagard®-705 L Silane based reactive water repellent impregnation.

PRODUCT DESCRIPTION

Sikagard®-705 L is a one-component low viscosity, solvent free, reactive impregnation for concrete and cementitious substrates based on silane technology with 99% active ingredient. Sikagard®-705 L complies with the highest requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class II & resistance to freeze-thaw cycles and chloride ion penetration) and is tested in accordance with NCRHP 224 Series II & IV.

USES

Sikagard®-705 L is used as water-repellent penetrating sealer (hydrophobic treatment) for absorbent substrates such as:

Parking decks▪ Bridge decks▪ Concrete highway surfaces▪ Ramps and Barriers▪ Cooling Towers▪ Stadiums▪ Natural stone substrates▪ Many other traffic bearing/reinforced concrete substrates and structures

CHARACTERISTICS / ADVANTAGES

Excellent penetration (~100% active content).▪ Economical and easy to use.▪ Reduces capillary water absorption, protection against driving rain and splashing on vertical areas.

Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment).

Non vapor barrier.▪ Long term efficiency, deep penetration.▪ Increases the resistance of concrete to freeze and thaw cycles and de-icing salts.

Low VOC content.▪ Resistant to sea water.▪ Ready and easy to use▪

SYSTEM INFORMATION

System Structure 2–3 coats either as stand-alone or combined with surface applied corrosion inhibitor and/or protective coating.

APPLICATION INFORMATION

Coverage Dependent on absorbency of the substrate as well as the required penetration depth: 240–360 sq.ft./gal per coat

Substrate Moisture Content < 5–6 % when measured with Tramex

Waiting / Recoat Times Can be overcoated with water and solvent based polymer paint - contact the proposed paint manufacturer for recommendations.

Sikagard®-705 L can be used as a water repellent primer under many Sikagard® protective coatings inclusive of water based dispersion.

Penetration of water is thus prevented at possible weak spots or in the event of damage to the top coat and the risk of consequential damages such as paint flaking can be reduced.

Waiting time: Minimum 5 hours, maximum 1 week.

Curing Treatment Sikagard®-705 L does not require any special curing but must be protected from rain for at least 4 hours at 68 °F (20 °C).

APPLICATION INSTRUCTIONS

SURFACE PREPARATION

Free of dust, dirt, oil, efflorescence and existing paint coatings, salt deposits or any contaminants that may affect the penetration of the chemical. Remove all grease, curing compounds, surface treatments, coatings, oils, etc.

Best results are achieved when Sikagard® 705 L is applied on 28 days old concrete – however, due to its high alkali resistance, it is still possible to apply as early as 3 days. Testing should always be done to ensure proper penetration depth. Best results are achieved on a dry, very absorbent substrate. All surfaces to be sealed must be dry, clean, sound before application.

Preparation Work: Concrete, masonry and natural stone surfaces must be prepared using mechanical means (sandblast, shot blast, pressure wash, etc.). Cracks in concrete more than 12 mils must be repaired prior to

Product Data Sheet Sikagard®-705 L March 2020, Version 03.02 020303010010000004

2 / 4 application of the hydrophobic treatment. If using water to clean, substrate should be visibly dry (i.e. no damp/ dark patches) before coating.

MIXING

Sikagard®-705 L is supplied ready for use and must not be diluted.

APPLICATION

Sikagard®-705 L is applied using a low-pressure spray, brush or roller, in a single pass from bottom up taking care not to let the product run. Apply subsequent coats “wet on wet”. On horizontal application, avoid ponding on the surface.

LIMITATIONS

Best results are achieved when Sikagard® 705 L is applied on 28 days old concrete – however, due to its high alkali resistance, it is still possible to apply it at a very early age as 3 days. Testing should always be done prior to application on early age concrete to ensure sufficient penetration depth.

Areas such as window frames which still need to be painted must be securely covered to avoid contact with Sikagard® 705 L.

Areas not to be impregnated such as window panes need to be protected from being accidentally contaminated with Sikagard® 705 L.

Sikagard® 705 L can damage some coatings and bituminous products.

Sikagard® 705 L can lead to darkening of concrete, apply sample areas first.
