decoSIL CH

• Cures, hardens and dustproofs freshly power-troweled concrete in one spray
• Cost-efficient: one application significantly improves your concrete floor in many ways at a relatively low cost
• Improves abrasion resistance and long-term durability
• Eliminates dusting and helps limit efflorescence
• Water-based, very low VOC, eco-friendly; LEED-relevant
• Better resistance to oil, grease and tire marks than untreated concrete
• Helps minimize hairline cracking and supports design strength of the slab
• Prepares the surface for paints, joint sealants, adhesives and later sealers
• Reacts fast, in one hour or less; once dry, the surface is ready for use

General

1. Shake the can or drum well first, but not too long, otherwise the product will foam.
2. Coverage: about 12–20 m²/kg on freshly power-troweled concrete. Always test a small area first.

On fresh power-troweled concrete

1. No special surface prep required. Apply decoSIL CH as soon as power troweling of the whole floor is finished, and at the latest the morning after the pour. The surface must be dry.
2. Apply evenly. For large areas, use the Densifier Applicator — faster, more even and more economical than hand spraying. One person can treat about 2,300 m² in roughly 1 hour. A low-pressure, high-volume sprayer also works on smaller jobs.
3. With the Densifier Applicator, decoSIL CH is spread evenly and no puddles are left behind. If you spray with a low-pressure sprayer and spread with a microfiber mop, the result can be uneven. So after 10–15 minutes, check where puddles are standing and mop them up.
4. Let the product dry.
5. Clean the floor with a scrubber-dryer. If you applied decoSIL CH directly after power troweling, do this the next morning. If you only apply it the morning after the pour, you can do this as soon as one hour after spraying.
6. Then cover the floor with protective sheeting for at least 7 days, preferably 14 days.
7. Clean your tools immediately after use with water.

Existing concrete

For existing concrete, use decoSIL.

Maintenance

1. For extra protection and gloss, apply decoFINISH. For daily care that also feeds silica into the surface, use decoCLEAN regularly.

When do I apply decoSIL CH?

As soon as power troweling of the whole floor is finished, and at the latest the morning after the pour. The surface must be dry. This applies to floors with or without dry-shake.

Can I use decoSIL CH on existing concrete?

No, decoSIL CH is meant for freshly power-troweled floors. For existing concrete, use decoSIL.

How much do I need?

About 12–20 m²/kg on freshly power-troweled concrete. Always test a small area first.

Should I use the Densifier Applicator or a low-pressure sprayer?

Preferably the Densifier Applicator: it spreads decoSIL CH evenly and leaves no puddles. On smaller jobs you can use a low-pressure, high-volume sprayer and spread with a microfiber mop. The result can then be uneven, so after 10–15 minutes check where puddles are standing and mop them up.

What do I do after applying it?

Let the product dry. If you applied decoSIL CH directly after power troweling, clean the floor with a scrubber-dryer the next morning. If you only apply it the morning after the pour, you can clean the floor as soon as one hour after spraying. Then cover the floor with protective sheeting for at least 7 days, preferably 14 days.

Does decoSIL CH leave a layer on the floor?

No. decoSIL CH is an impregnating agent: it soaks into the concrete and forms no layer on the surface.

When can I polish the floor?

After 10 days if the temperature in the hall is above 25 °C, otherwise after 14 days.

How do I maintain the floor?

For extra protection and gloss, apply decoFINISH. For daily care, use decoCLEAN regularly; it also feeds silica into the surface.
