How can construction issues be avoided when installing EPDM rubber flooring?

Many people attribute quality issues with EPDM rubber flooring used in communities, kindergartens, or basketball courts to the material itself. How can we prevent construction-related problems with EPDM rubber flooring? Typically, the main issues are: 1) delamination; 2) color variation; and 3) uncured material. So how can we avoid these problems with EPDM rubber flooring? First, purchase materials from manufacturers with consistent quality; second, ensure that workers possess the necessary skills. Construction should follow established standards—avoid haphazard or arbitrary practices. A detailed analysis is provided below:

Many people attribute quality issues with EPDM rubber flooring used in communities, kindergartens, or basketball courts to the material itself. How can construction problems with EPDM rubber flooring be prevented?

Typically, the main issues are 1) threshing, 2) color variation, and 3) failure to cure.

So how can we avoid problems with EPDM‑based rubber flooring during installation? First, source materials from manufacturers with consistent quality; second, ensure the installers are skilled. Installation should follow established standards—avoid haphazard or arbitrary procedures. A detailed analysis is provided below:

I. There may be several reasons why grains fall to the ground.

1. The glue ratio is too low.

2. If too much adhesive is applied, the surface may easily bubble; always adhere strictly to the recommended ratio of adhesive particles.

II. Color Variation Issue: This is primarily due to particle‑quality problems with the main material manufacturer, possibly stemming from low adhesive content or an unstable formulation. We recommend, when using as many particles as possible, avoiding first thoroughly mixing the adhesive and then adding it in the proper proportion.

3. On-site non‑curing: First, there’s the issue of the manufacturer’s materials. Even when you add a thinner, it may still contain alcohol. During oil draining, black particles tend to fail to solidify. Some of these black particles look quite appealing and are elastic—meaning they haven’t been cured with any adhesive!

Therefore, only by ensuring product quality and proper installation prior to construction can construction defects in EPDM rubber flooring be effectively prevented. Only reputable manufacturers of high‑strength EPDM rubber flooring can deliver such results. These issues could have been avoided; they typically arise only at small‑scale contractors who lack the necessary qualifications, pursue profits blindly, and cut corners.

A key feature of EPDM construction materials is their wide variety, making them widely used in settings such as kindergartens and children’s playgrounds.

I. Requirements for the Foundation Base

1. Asphalt concrete or cement concrete may be used for the base layer, provided it meets specified strength and stability requirements (cement concrete bases must be provided with contraction joints, and a waterproofing layer is not permitted).

2. Frost heave, freeze‑thaw cracking, and other forms of non‑uniform frost heave are strictly prohibited on the foundation.

3. The foundation shall have good flatness and the specified slope.

4. The base surface shall be kept clean and dry. After the foundation is completed, a maintenance period of at least 21 days is required.

II. Construction Process Requirements

1. Surface pretreatment. On the basis of meeting the required standards, first clean the surface with butyl acetate to remove any dirt or foreign matter. After cleaning, apply the primer evenly to the substrate (mixing diluent and resin at a ratio of 3–4:1) to enhance adhesion to the floor.

2. Conduct small-scale trials prior to construction. Pay close attention to material usage, ensuring that the mix proportions and curing times are within acceptable parameters.

3. The on-site thickness shall comply with the specified requirements.

4. In the marked area, measure the position of the process line and apply polyurethane paint by spraying.

III. Precautions for EPDM Installation

1. The construction temperature shall be between 15 and 35°C.

2. The paving equipment used shall be adjusted uniformly as required.

3. The mixture is thoroughly and uniformly blended.

4. Trim neatly.

5. After on-site completion, inspect and clean up any residual materials left at the site.
