The Strength of Diamond. The Confidence of a Lifetime.

Dymond Coatings are engineered with the same qualities as their namesake β€” tough, long-lasting, and built to bond for life. That’s why we back every eligible Dymond kit with our Lifetime Promise: if your floor fails due to a verified product defect, we’ll replace the material or issue a credit toward your next job. This warranty applies to complete Dymond systems (primer, base coat, and topcoat) when installed on indoor concrete surfaces and applied according to Dymond’s preparation and application guidelines. Covered issues include delamination caused by faulty resin blends, curing failure due to batch defects, and contamination introduced during manufacturing or packaging. To qualify, the product must be within shelf life, used under proper storage conditions, and installed using only Dymond components.

This warranty does not extend to issues arising from improper surface preparation, substrate contamination, excessive moisture vapor, impact or abuse, substrate movement, or UV discoloration of white/light epoxies. Installations over wood, tile, or outdoor surfaces are excluded unless specifically approved. Cosmetic issues such as texture variation, microbubbling, or minor tint shift are not covered. Warranty coverage is limited to the original purchaser and is non-transferable. Claims must be submitted with photographic evidence of each install stage and full batch documentation. Dymond reserves the right to determine whether the cause of failure falls within warranty scope.

This Promise applies to most DIY and light commercial indoor projects. Larger commercial and industrial installations may be eligible for custom coverage β€” contact us for terms.

Can This Be Installed Over My Existing Floor?

Yes, in many cases, but the floor underneath has to be clean, solid, and mechanically prepared. The coating can only bond as well as the surface it is applied to.

Every floor is different. When coating over anything other than properly prepared concrete, we strongly recommend applying a small test area first.

Bare Concrete

Best Surface

This system is designed to bond to properly prepared concrete. The concrete must be clean, dry, sound, and mechanically ground or shot blasted.

Existing Epoxy

Good With Prep

This system can be installed over an existing epoxy coating if the old coating is firmly bonded, clean, sound, and fully deglossed.

Tile

Conditional / Test First

Can be installed when tile is firmly bonded, clean, degreased, abraded, and tested first. Installation is done at your own risk.

VCT Tile

Conditional / Test First

Many customers successfully coat over VCT, but the bond depends on tile, adhesive, waxes, moisture, and movement. Installation is at your own risk.

Wood

Conditional / Scratch Coat

Requires a scratch coat first. Wood installations are done at your own risk. Always test first.

Required Surface Prep

For a strong bond, the surface must be mechanically prepared. Cleaning alone is not enough.

1

Grind or Shot Blast

The floor must be mechanically ground or shot blasted to create a surface profile the coating can grip.

2

Remove Contamination

Oil, grease, wax, soap residue, dust, old adhesive, sealers, and loose material must be removed before coating.

3

Repair Cracks & Defects

Cracks, holes, divots, and damaged areas should be filled before coating for a stronger, smoother finish.

4

Test First When Unsure

For tile, VCT, wood, unknown coatings, sealed floors, or questionable surfaces, apply a small test area.

Installation Questions We Get Every Week

Click any question to expand
? Does the floor need to be ground?

Yes. For a strong bond, the coating needs a clean, mechanically prepared surface profile.

? What does delamination mean?

Delamination is when the coating separates, peels, bubbles, or lifts from the floor underneath.

? Can this be installed over an existing epoxy?

Often yes, if the existing coating is fully bonded, clean, sound, abraded, and tested first.

? Can this be installed over VCT tile?

Sometimes, but the installation depends on the tile, adhesive, waxes, movement, and moisture. Test first.

? Can this be installed over wood?

Wood is conditional and normally needs a scratch coat. Always test first.

? Can this be installed over tile?

Tile can be conditional. It must be firmly bonded, cleaned, abraded, and tested before a full installation.

OK

Still Not Sure? Test Before You Coat.

Every floor is different. If you are coating over tile, VCT, wood, an unknown coating, sealed concrete, or a questionable surface, apply a small test area first before installing the full system.

The coating can only perform as well as the surface underneath it.
