SolidCor 218 Terrazzo-Look Epoxy Flooring System

SolidCor 218 Terrazzo-Look Epoxy Flooring System

SolidCor 218 is a terrazzo-look self leveling epoxy resurfacer designed to create a seamless, high-gloss decorative floor with a premium granite-like appearance.

The system combines a two-component, 100% solids clear epoxy binder with Dymond TerraMatrix™ Decorative Aggregate Blend, producing a smooth stone-inspired finish with the visual depth of polished terrazzo, without the cost, weight, or installation complexity of traditional terrazzo.

Applied at approximately 1/16" thickness, SolidCor 218 flows into a durable decorative surface suitable for interior concrete floors, retail spaces, showrooms, residential interiors, countertops, molds, and other areas where a high-end seamless finish is desired.

Unlike traditional terrazzo, SolidCor 218 is designed as a resinous resurfacing system, making it a practical option for decorative projects where a seamless stone-look finish is desired without heavy cementitious installation methods.

For best results, apply over a properly prepared and primed substrate using BondMaxx 113 or BondMaxx 127. For added chemical resistance, wear performance, gloss retention, or improved UV-related color stability, SolidCor 218 may be topcoated with a suitable urethane or polyaspartic topcoat such as CrystalCoat 325 or CrystalCoat 328.

  1. PRODUCT STORAGE: Store product in an area that allows the material to reach normal room temperature before use. Continuous storage should be between 60°F and 90°F. Low temperatures or significant temperature fluctuations may cause product crystallization.
  2. SURFACE PREPARATION: The most suitable surface preparation is a fine brush blast/shot blast to remove all laitance and provide a suitable surface profile. All dirt, foreign contaminants, oil, and laitance must be removed to ensure a trouble-free bond to the substrate. A test should be made to determine that the concrete is dry. This can be done by placing a 4' x 4' plastic sheet on the substrate and taping down the edges. If, after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating. The plastic sheet test is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.
  3. PRODUCT MIXING: This product has a mix ratio of one full gallon, approximately 9.20 lb, Part A to one full half gallon, approximately 4.25 lb, Part B and one 18 lb bag of Dymond TerraMatrix™ Decorative Aggregate Blend. Standard packages are in pre-measured kits and should be mixed as supplied. We highly recommend that kits are not broken down unless suitable weighing equipment is available. After the two liquid parts are combined, add the provided aggregate blend and mix well with slow-speed mixing equipment, such as a jiffy mixer, until the material is thoroughly mixed and streak-free. After mixing, transfer the mixed material to another pail, also known as the transfer pail, and remix. The material in the transfer pail is now ready to be applied to the primed substrate. Remix occasionally to help prevent settling of the aggregate. Improper mixing may result in product failure.
  4. PRIMING: A suitable primer should be used before applying this product. See the front side of this technical data sheet for primer information. If a primer is not used, more porous substrates may cause outgassing and possible surface defects.
  5. PRODUCT APPLICATION: The mixed material can be applied with a 3/8" V-notched serrated squeegee at the recommended thickness, then back rolled very lightly with a spike or loop roller cover. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process.
  6. RECOAT OR TOPCOATING: If you choose to topcoat this product, first ensure the coating has tacked off. The surface should then be lightly deglossed to ensure a trouble-free bond before applying recoats or topcoats. Colder temperatures will require more cure time before recoating or topcoating can begin. Before recoating or topcoating, check the coating to ensure no epoxy blush has developed, such as a whitish, greasy film or deglossing. If blush is present, it can be removed with a standard detergent cleaner before topcoating or recoating. Many polyaspartic and urethane coatings are suitable for use as topcoats.
  7. CLEANUP: Use xylol.
  8. FLOOR CLEANING: Caution: Some cleaners may affect the color of the installed floor. Test each cleaner in a small area using your cleaning technique. If no ill effects are noted, you can continue cleaning with the product and process tested.
  9. RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured. See the technical data under full cure. It is best to let the floor remain dry for the full cure cycle. Depending on the complete system application, the surface may be slippery, especially when wet or contaminated. Keep surface clean and dry.

The Strength of Diamond. The Confidence of a Lifetime.

Dymond Coatings are engineered with the same qualities as their namesake — 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 — 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.
