Surface preparation:
- Surfaces should be structurally clean, oil free, no grease or any other contaminants.
- Use water pressure jetting to finally wash.
- Before applying, the surface must be saturated with water (but no water remains)
Placing:
- Use a brush, roller or pressure nozzle to evenly distribute BestSeal AC408 over the entire prepared surface with the required amount in a certain direction. Curing material for about 6 to 8 hours (depending on weather conditions, climate).
- When applying the second layer, it should be done in a direction perpendicular to the first application to minimize the process of air entraining between the two layers of material.
Precaution:
- Properly stirring before use.
- DO NOT work on non-saturated or puddles surface.
- DO NOT apply more than 1.2kg/m2 / layer.
- For the high absorbing surface, It is needed to dilute BestSeal AC408 with 10 ÷ 12 % clean water (by weight) in order to increase deeply absorbing capacity of material into substrate
- Apply at least two layers.Do not apply BestSeal AC408 while it rains. In case of raining when applying, stop the job and cover carefully all applied area.
- For the surface area under constant mechanical stress during use, it must be covered a cement-sand layer (after 24 to 48 hours of application) to protect BestSeal AC408 layer against mechanical stress on materials surface.
- BestSeal AC408 is able to self-maintain by air, no water to humidify the applied surface (in the case of no protective cement-sand coating).
Cleaning:
- Clean equipments immediately after the execution and before the mixture’s hardening.
Safety:
- BestSeal AC408 is non–flammable light alkaline.
- BestSeal AC408 is allergic to skin.
- Protective clothing is highly recommended.
- In case of contact with eyes, rinse immediately with plenty of clean water and
seek medical advice.
