decoSIL

• Makes concrete harder, more abrasion resistant and durable
• Eliminates dusting
• Penetrates 8–16 mm into the concrete
• Makes concrete easier to polish
• Economical dustproofer and hardener for industrial floors
• Very low VOC (< 1.0 g/L); qualifies for LEED points
• Internal test: up to 40% higher abrasion resistance, Mohs hardness from 4 to 6

1. Surface: Clean, dry, free of dust, oil, curing membranes, coatings or other barriers. Open the pores if needed by light grinding or sanding on sealed or contaminated floors.
2. Shake / stir the product before use. Protect adjacent surfaces; remove overspray promptly with a damp cloth and soap.
3. Apply evenly with a low-pressure, high-volume sprayer (or microfiber mop). The product penetrates and dries within 15–30 minutes. Redistribute puddles with a microfiber mop. Re-wet dry spots with a light extra pass. Even good concrete can be fairly porous. If you notice the product soaks in very quickly, apply decoSIL several times.
4. Do not allow traffic until the surface is dry. Reaction is typically fast (about one hour or less under normal conditions); the floor is ready for use when dry.
5. Polishing: If used in a diamond polishing sequence, apply after an early resin-bond step (often from grit ~100 upward), allow full penetration (surface no longer glistening), then continue polishing.
6. Optional finish: For extra protection, gloss and easier cleaning, apply decoFINISH (or another Deco Crete sealer) after densifying. Maintain with decoCLEAN.
7. Coverage (indicative): approx. 12–18 m²/kg depending on porosity and conditions — verify on a test patch.
8. Safety: Alkaline product — wear eye protection and gloves. Keep out of reach of children. Protect from freezing; stir before use.

Tip: Want to work fast and accurately, without spray mist? Use the Densifier Applicator. It spreads the hardener evenly over the floor, so you get a consistent result with less effort.

Which concrete is decoSIL for?

Medium-quality concrete with average porosity. For very dense concrete use decoLIT; for very porous concrete use decoSOD-HS1.

How much do I need?

Approx. 12–18 m²/kg. Always test a small area first.

How long does it take to dry?

It penetrates and dries within 15–30 minutes, longer in cool or humid weather. Remove any tacky excess with water.

Can I use it while polishing?

Yes, after the resin pad step with grit 100. Continue polishing once the surface no longer glistens.

Does porous concrete need more than one application?

Even good concrete can be fairly porous. If you notice the product soaks in very quickly, apply decoSIL several times.

Can decoSIL make an old, dusty floor dust-free again?

Yes. Clean the floor thoroughly first so the product can penetrate. Combining it with polishing gives the best result, but it is not required.

Can decoSIL stop coloured concrete from releasing pigment?

Yes. Combined with polishing it stops the pigment from rubbing off. Read the Uden case
