MAX GRIP Made Simple: Use It for Epoxy Prep or Traction Improvement
MAX GRIP is an acid etch treatment for bare mineral surfaces. Use it in one of two ways: prep bare concrete before an epoxy coating (such as Dura Grip), or increase traction on compatible unsealed surfaces.
Follow the TDS for correct application and do not allow MAX GRIP to dry on the surface.
Why surfaces stay slippery and coatings fail?
Concrete and mineral surfaces often look “clean” while still being the wrong surface for traction or coatings. Smooth finish, dust, residues, and sealers can keep a floor slick. Even worse, they can prevent coatings from bonding properly, which is why you see peeling, patchiness, and early failure.
MAX GRIP solves a specific problem: it opens the surface profile so the next step, whether that is a coating or traction treatment, actually works.
Which one do you need?
Choose Path A if you are applying a coating
You want a durable, high traction system. You are applying an epoxy coating like Dura Grip.
Goal: surface profile and adhesion.
Choose Path B if you want traction improvement without a coating
You want extra grip on compatible unsealed mineral surfaces and you are not coating afterwards.
Goal: traction increase on the existing surface.
Before you start: the surface must be bare and absorbent
MAX GRIP is intended for bare, unsealed mineral surfaces.
Do a quick water drop check:
If water beads, the surface is sealed or contaminated and MAX GRIP will not etch evenly until that is corrected.
Do not use on previously coated or painted floors.
Path A: Prep bare concrete for epoxy coatings (best for Dura Grip systems)
Why this method works
Epoxy coatings need the right surface profile to bond. If the surface is too smooth or contaminated, the coating can fail early. MAX GRIP is the prep step that helps the coating perform.
Simple process
-
Clean and degrease thoroughly
Remove dirt and residues so the etch can contact bare concrete. -
Apply MAX GRIP and spread evenly
Use a nap roller or suitable applicator for consistent coverage. -
Keep the surface wet
Do not let MAX GRIP dry on the surface. -
Rinse thoroughly and remove excess water
Rinse with clean water, then use a squeegee or wet vac if available. -
Let the surface dry completely before coating
Once dry, apply your epoxy coating following its TDS.
What to expect: the surface should feel like fine grit sandpaper after etching.
Path B: Increase traction on compatible unsealed mineral surfaces
Why this method works
On compatible unsealed mineral surfaces, controlled etching can increase bite and reduce slipperiness.
Compatible surfaces typically include
Unsealed concrete, quarry tile, slate, brick, and other compatible unsealed mineral surfaces.
Simple process
- Clean the surface
-
Apply MAX GRIP evenly and keep it wet
Do not let it dry. - Test traction as you go and note the dwell time
-
Neutralize, rinse, and allow to dry
Once dry, the surface is ready for use.
Best practice: MAX GRIP + Dura Grip for a durable high traction floor
If you want the most durable traction improvement, this is the system approach:
Prep bare concrete with MAX GRIP, rinse and dry fully, then apply Dura Grip per the TDS.
Garage floors: For best protection and to help prevent hot tire marks, a clear two-part epoxy topcoat is recommended. SlipDoctors Top Coat is recommended.

MAX GRIP FAQs
Can I use MAX GRIP on a previously coated floor?
No. Coatings must be removed first.
How do I know if my surface is sealed?
If water beads, it is sealed or contaminated.
Do I have to coat after using MAX GRIP?
Only if you want a coated system. For traction improvement, MAX GRIP may be used as a standalone treatment on compatible unsealed surfaces.
How long should MAX GRIP stay on the surface?
Treatment time varies by surface. Keep the surface wet and do not let MAX GRIP dry. Follow the TDS and test a small area first.
What should the concrete feel like after etching for epoxy prep?
After etching and rinsing, the surface should feel like fine grit sandpaper. If it still feels smooth or sealed, the surface may need additional prep before coating.
