SikaTop®-501 Seal — Cement-Based Capillary Crystalline Waterproofing Material
SikaTop®-501 Seal is a cement-based capillary crystalline waterproofing material applied against surface water in old and new structures from both negative and positive sides. Supplied as a powder and mixed to a brushable slurry, it fills capillary gaps by forming permanent, insoluble crystals that block the passage of water, protecting the concrete while remaining water-vapour permeable and freeze-thaw resistant.

Application guide
Application guide (5 easy steps)
- Substrate PreparationThe substrate must be sound and clean. Repair weak or honeycombed concrete and remove laitance. Dampen the surface thoroughly before application; the substrate must be saturated but without standing water.
- MixingAdd the powder to clean water and mix with a 400-600 rpm mixer for 3-5 minutes to a homogeneous slurry. Wait 3-5 minutes, then remix for about 30 seconds before use.
- First CoatApply the first coat by brush onto the dampened substrate, working the slurry well into the surface.
- Second CoatApply the second coat once the first has sufficiently cured (typically 3-5 hours depending on temperature); the interval between coats must be less than 6 hours.
- CuringProtect from rapid water loss. Do not use curing compounds. Keep the coating wet for 5-7 days. Clean tools with water immediately after use.
