Si20 MB – Water Based Moisture Barrier
Price range: $95.00 through $285.00
Si20-MB is a ready to apply, silicate based moisture barrier formulation for rendering concrete impermeable to moisture. Si20-MB acts by reacting with concrete and permanently blocking concrete pores.
Key advantages
- Moisture barrier for impervious coverings
- Makes concrete impermeable
- Densifies and hardens concrete, increasing tensile and compressive strength
- Solvent and VOC free
- Environmentally friendly
- Compatible with most floor covering systems

How to Apply
Developed in Australian to suit our unique conditions, see our full range or use this chart to help choose which sealer is right for the job.
Preparation
- Clean the surface then rinse thoroughly
- Sealer can be applied to a damp surface
- Free of visible or pooled water, broom off or use a blower to remove
- Surface needs to be touch dry
Sealer Dilution
>>> Always add water to the concentrated sealer!
Step One
Add 5 L concentrate to 20 L bucket.
Step Two
Add 15 L of water.
Step Two
Drill mix or lid & shake ~30 sec.
Sealer Application
- Working from the furthest point, begin spraying the sealer while walking backwards
- Sealer should be sprayed in an even flood coat at a rate of approximately 5m2 per litre – depending on porosity
- Sealer should remain wet on the surface for at least 5 minutes
- Only one flood coat is required, however if the surface is very porous, additional sealer can be applied
- Avoid over spraying sealer on surrounding surfaces.
Application to dense, smooth or non textured surfaces
- A microfiber mop or similar is required to spread the sealer after the initial light spray
- A second application may be required if the surface still accepts sealer
- The surface should be buffed or wiped dry with the mop after each application.
Excess Sealer
- Any sealer that is still present on the surface after 10 to 12 minutes will need to be removed.
- This can be done by brooming out or blowing off pooling.
- While it is safe to walk on wet sealer, care should be taken to minimise footprints.
Simple Guidelines
- Don’t apply if pools of water present
- Don’t apply to hot surfaces (>30 degC), mist with water to cool
- Don’t allow sealer to pool, remove excess
- Avoid contacting surfaces not meant to being sealed
- Don’t apply if rain expected in at least 24 hours
Maintenace
- Cleaning of sealed surfaces recommended every 12 months with NPH Cleaner
- Harsh chemicals: acids, alkalines, solvents will effect sealer longevity
- Minimal pressure required
- Contaminants/dirt will be close to surface
- Time to reapply? – NO STRIPPING REQUIRED
