How To Burnish Concrete Surfaces – The Integra Method
1. Concrete Placement & Finishing
Mix Design:
Use a minimum
32 MPA
concrete mix for strength and density.
Initial Finishing:
Use a bull float immediately after screeding.
Power Trowelling:
Perform multiple steel trowel passes using a power trowel to develop the paste and close the surface.
Tip:
The tighter and smoother the finish, the better the burnish will look.
2. Apply
DEEPCURE
Curing Agent
Timing:
Apply after final trowel finishing when the surface can be walked on without leaving marks.
Method:
Use a low-pressure sprayer to apply DEEPCURE evenly across the surface.
Benefit:
DEEPCURE penetrates deeply, locking in moisture without leaving a surface film, allowing densifier and sealer to bond properly later.
3. Allow Proper Curing Time
Minimum:
Let the concrete cure for at least
7 days
before applying densifier or burnishing.
Care:
Keep surface protected from stains, dirt, and damage during curing.
4. Apply
DensaCURE
Lithium Densifier
Preparation:
Clean the surface. Do not acid wash.
Application:
Spray DensaCURE evenly, ensuring full surface coverage. Keep damp for 15–20 minutes, then allow to fully dry.
Effect:
Reacts with the concrete to form a harder, denser surface, ideal for polishing or burnishing.
5. Burnishing Process
Timing:
Wait 24 hours after DensaCURE application before burnishing.
Equipment:
Use a high-speed burnisher (1500+ RPM) with resin or diamond-impregnated pads.
Pad Sequence:
800-grit → 1500-grit → 3000-grit (or finer, depending on desired finish).
Technique:
Burnish in overlapping passes. Keep the surface dry and clean throughout.
6. Apply TOPSEAL for Final Protection
Purpose:
TOPSEAL provides long-term resistance to moisture, stains, and oils without affecting surface gloss.
Timing:
Apply only after final burnishing and once the surface is cool and dry.
Application:
Use a microfibre applicator or low-pressure sprayer. Apply in thin, even coats. Avoid puddling.
Dry Time:
Touch-dry in 30 minutes. Ready for light foot traffic in a few hours.
✅ Final Outcome
Tightly finished, dense and dust-proofed slab
Natural sheen enhanced by burnishing
Zero membrane removal required
Fast application, minimal downtime
Enhanced long-term durability and easy maintenance
