APEX Poly Fuse Countertop Primer
Stone Coat Apex Poly Fuse Countertop Primer is the foundation of the APEX Countertop System, engineered to chemically bond laminate, tile, cultured marble, granite, metal, and MDF to our APEX Polyaspartic Countertop Coating product.
Two thinly applied coats create exceptional adhesion while concealing underlying colors and patterns to prevent bleed-through. The result is a smooth, uniform surface that resists chipping, cracking, and peeling, ensuring a luminous, lasting white stone aesthetic.

APEX TECHNOLOGY
Redefining What’s Possible
The industry has long accepted yellowing, dulling, and color shift as the tradeoff for white countertop finishes. APEX was created to change that.
Developed from the ground up as a purpose-built UV-stable system, APEX is not an evolution of previous coating technologies or formulations — it's an entirely new approach designed to preserve brilliant white tones and stone-inspired aesthetics with exceptional long-term color integrity.

Frequently asked questions
What is APEX—is it epoxy?
What is APEX—is it epoxy?
APEX is a next-generation countertop coating system from Stone Coat Countertops, engineered for bright, high-end stone and marble looks with better color confidence, clarity, durability, and long-term performance.
APEX is not epoxy. It is made with aliphatic polyaspartic technology and designed to be poured thick to mimic the depth and movement of natural stone while resisting yellowing, even in direct sunlight. The complete APEX system includes a primer, white dye, countertop coating, and finishing spray, with each component engineered to work together for beauty, durability, and long-term color stability.
APEX also has its own workflow. It moves less than epoxy, gels quicker, uses no-torch bubble control, and requires disciplined timing during application. It is built specifically for true whites and light-colored countertop designs, giving customers more control and confidence when creating bright surfaces.
Does APEX yellow?
Does APEX yellow?
For years, yellowing has been one of the biggest limitations of epoxy countertop coatings. APEX was engineered to move beyond it and redefine what’s possible.
APEX Polyaspartic Countertop Coating is an industry-leading UV-stable formula specifically designed to preserve true whites and resist the discoloration traditionally associated with epoxy countertop coatings.
Is it possible to apply APEX over existing countertops?
Is it possible to apply APEX over existing countertops?
Yes. APEX can be installed over existing countertops, including existing epoxy countertops, as long as the surface is solid, stable, and properly prepared.
APEX Poly Fuse Countertop Primer is engineered to bond to a variety of surfaces, including laminate, tile, cultured marble, granite, metal, MDF, existing epoxy, and new builds. Each surface may require a different prep path, so follow the approved prep system for the specific countertop you are coating.
Do not apply APEX over failing substrates, loose material, peeling coatings, or surfaces that are not structurally sound. Solid and properly prepared is the rule.
Can I torch APEX?
Can I torch APEX?
No. APEX is a no-torch workflow.
Epoxy often uses a torch to help release bubbles and manipulate the surface, but APEX is designed to work differently. Do not use a torch on APEX. Torching APEX will lower the working time and affect the cured finish. Instead, use APEX Surface Control Finishing Spray during the approved wet working window.
Is APEX replacing Stone Coat Countertop Epoxy?
Is APEX replacing Stone Coat Countertop Epoxy?
No. APEX expands the Stone Coat portfolio of countertop solutions rather than replacing existing products. Our Stone Coat Countertop Epoxy kits remain an excellent choice for artistic stone looks, dramatic veining, metallic effects, and a wide range of custom countertop designs. APEX was specifically engineered for projects where preserving brilliant whites and light-colored aesthetics is the priority.
