Mix special polyurethane adhesive with matching color paste, roll or scrape the mixture directly on the cleaned original EPDM surface. The glue penetrates particle gaps, rebinds loose granules, seals pores, and forms a colored protective film on the surface to realize reinforcement and color restoration. It belongs to surface sealing & reinforcement renovation.
On the treated original floor, mix new fine EPDM particles with standard adhesive, and pave a new thin granular layer (usually 2–4 mm) on the old surface. It belongs to overlay resurfacing renovation.
Process: Site cleaning → Local patching → Color matching & glue mixing → Overall roller coating → Edge trimming → Curing
Features: Simple steps, no particle stirring and large-area paving. Short construction period; a regular venue can be finished within 1 day.
Curing time: 24–48 hours for full use.
Process: Site cleaning & loose particle removal → Base repair & primer coating → Particle-adhesive mixing → Overall paving → Compaction & line marking → Curing
Features: More procedures, required professional mixing tools and paving tools. Longer construction period, 2–3 days for conventional venues.
Curing time: 48–72 hours before putting into use.
Advantages: Uniform overall color, no local color difference; completely covers faded, whitened and mottled areas. The surface retains original granular texture slightly.
Disadvantages: Long-term outdoor use will cause gradual glue layer fading; cannot restore the brand-new granular three-dimensional sense. Color is limited to the tone of color paste.
Advantages: Restores complete granular appearance and three-dimensional texture, same as new floor. Rich color options, can re-design patterns and color partitions.
Disadvantages: Slight color difference may exist between new layer and old edge joints if construction is not standardized; local repair parts are easy to leave traces.
Advantages: Strong permeability, effectively bonds loose old particles and seals surface voids; improves surface compactness and anti-sand loss ability. Good waterproof performance.
Disadvantages: Only acts on the surface layer, cannot repair floors with severe internal aging and poor overall elasticity. The glue layer will wear thin after 2–3 years of high-frequency use.
Service life: 3–5 years.
Advantages: The new granular layer has complete elasticity, shock absorption and anti-slip performance, which fully recovers the original functional indexes of EPDM floor. The new layer is wear-resistant and anti-aging.
Disadvantages: The bonding interface between new and old layers is a weak point; water immersion or base movement may cause delamination and warping in the later stage.
Service life: 5–8 years.
Low material and labor cost; no need for a large number of new EPDM particles. The total cost is about 30%–50% of thin resurfacing.
Low resource waste, fully utilizes the original floor.
Higher cost due to additional consumption of EPDM particles and special paving materials. Labor cost is higher for complex processes.
Produces a small amount of waste during cleaning loose old particles.
Suitable for:
Floors with stable base, slight particle loosening, surface fading, dusting and minor wear;
Budget-limited projects, routine maintenance and rapid renovation;
Kindergartens, community fitness areas and parks with medium usage frequency.
Not suitable for:
Floors with large-area particle falling, serious elasticity attenuation, base hollowing and cracking.
Suitable for:
Floors with moderate wear, partial particle shedding and obvious elastic decline (base still intact);
Projects requiring brand-new appearance, re-coloring and pattern transformation;
School playgrounds, activity venues with high usage frequency and high performance requirements.
Not suitable for:
Severely hollowed, cracked floors (needs overall reconstruction first); projects with tight construction schedule and limited budget.
Simple maintenance: Only regular cleaning with neutral detergent. When the surface glue layer fades or wears after years of use, secondary color glue coating is available.
Same daily maintenance as new EPDM floor. Need regular inspection on the joint of new and old layers to prevent delamination. Once local particles fall off, repair with matching particles and glue.
✅ Pros
Low cost, fast construction and quick venue reuse;
Uniform color, good surface sealing effect, solves dusting and loose particles effectively;
Simple operation, low requirements for construction teams.
❌ Cons
Cannot restore the complete elasticity and three-dimensional granular sense of new floor;
Short service life, suitable only for mild damage;
The surface glue layer will wear and fade gradually in high-frequency use areas.
✅ Pros
Restores full elasticity, anti-slip and wear resistance; long service life;
Brand-new granular appearance, support color and pattern redesign;
Better overall performance, applicable to venues with high use intensity.
❌ Cons
High cost, long construction and curing period;
Higher construction technical requirements, easy to have delamination and joint color difference if constructed improperly;
More working procedures and larger impact on venue normal use.
For mild aging, fading, dusting and slight particle loosening, limited budget and tight schedule: Choose colored adhesive with color paste coating.
For moderate wear, poor elasticity, demand for new appearance and long-term use: Choose thin-layer EPDM particle resurfacing.
If the base has hollowing, large cracks and serious delamination: Neither method is applicable; overall demolition and reconstruction is required.
