Sethard L is recommended for new and old cementitious surfaces, such as concrete floors and granolithic paving. It should not be used to renovate concrete which is already disintegrating. Typical applications include:
Approx. 12 - 14 m²/ liters on freshly poured concrete surfaces.
Store in dry area away from direct sunlight, at temperatures range between 5°C and 35 °C.
Sethard L has a shelf life of 12 months from date of manufacture if stored in proper conditions and un-opened packs.
The substrate must be clean, dry, structurally sound, dense and free from oil, grease, dust and other contaminants. A clean surface will ensure maximum penetration of Sethard L into the concrete surface.
Surfaces contaminated by oil or grease should be treated with suitable chemical de-greaser then washed with clean water.
Areas deeply contaminated by oils or grease, should be treated by hot compressed air.
All contamination and laitance must be removed before Sethard L application to allow for effective penetration.
Sethard L may be applied on newly laid concrete immediately after final trowelling using a low pressure sprayer fitted with a 1.9 ltr/ min (0.5 gpm) sprayer tip.
Apply one coat of Sethard L at the rate of 12 - 14 m²/ liters without producing puddles. If surfaces dry immediately, apply more materials as the surfaces should remain wet for 5 - 10 minutes.
Allow treated surfaces to dry, then apply curing compound at the specified rate using a suitable product from setseal range.
Sethard L can be applied to cured concrete of any age. Apply one coat of Sethard L at the rate of 9 - 10 m²/ liters using a low pressure sprayer fitted with 1.9 liters/ minute (0.5 gpm) sprayer tip.
Do not apply excess material to avoid material puddling. Use soft bristle broom to evenly spreed Sethard L and ensure uniform wetting. If surfaces dry immediately, apply more materials as the surfaces should remain wet for 5 - 10 minutes.
Before products dries, tools and equipment can be cleaned with clean cold water.
HEALTH AND SAFETY
Sethard L should not come in contact with skin and eyes, however any accidental splashes to the eyes must be rinsed with clean water and seek medical advice. Suitable protective gloves and goggles should be worn.
