1. Classification of Rubber Flooring

Rubber flooring is mainly divided into two categories:

- Rubber flooring tiles

- Rubber flooring rolls

Specifications:

Tiles: 500mm × 500mm, 600mm × 600mm, 1000mm × 1000mm

Rolls: 1220mm × 15000mm

Thickness: 2.0mm, 2.5mm, 3.0mm, 3.5mm, etc. Final specifications depend on manufacturer products.

2. Application Areas

Rubber flooring is widely used in airports, power plants, exhibition halls, gyms, training centers, stages, computer rooms, substations, precision instrument storage areas, defense ammunition depots, naval anti-slip decks, office buildings, ships, kindergarten facilities, elderly activity centers, swimming pools, massage rooms, medical institutions, shopping centers, sports courts, running tracks, and rooftop waterproof sports fields.

It features strong adhesion, good flexibility, impact resistance, and an aesthetically smooth surface. In China, rubber elastic flooring has developed rapidly in recent years, with annual growth exceeding 20%.

3. Construction Requirements

3.1 Pre-construction Preparation

1.The cement mortar leveling layer must be completed and accepted according to building ground engineering quality standards.

2. Understand the structural condition of the site and prepare a detailed construction plan.
3. Confirm flooring type (tiles or rolls), batch consistency, color variation, and dimensional differences.
4. Prepare tools such as floor grinder, industrial vacuum cleaner, heavy pressure roller (50–75kg), cutting tools, and other specialized equipment.

4. Substrate Requirements

New concrete surfaces must be machine troweled without dry cement powder and cured for at least 28 days.

5. Substrate Issues (Inspection Notes)

Common site inspection items include moisture testing, flatness checking, and hardness evaluation. (Image placeholders omitted)

6. Construction Process

Base grinding and cleaning → defect repair → primer coating → cement-based self-leveling layer → rubber flooring installation → finishing treatment

6.1 Base Inspection

- Moisture content must be < 8%
- Concrete strength ≥ C20
- Surface hardness ≥ 1.2 MPa
- Surface must be clean, dense, crack-free, oil-free, and dust-free
- Flatness deviation within 3mm over 2m

6.2 Primer Application

Apply penetrating water-based primer in 2–3 coats. Cross-application is required for the first two coats to ensure uniform coverage.

6.3 Self-leveling Layer

After primer curing, apply cement-based self-leveling compound when surface is properly sealed. Ensure even spreading.

6.4 Grinding

After approximately 48 hours of drying, grind the surface until a smooth and solid base is exposed with a glossy finish.

6.5 Installation

After fine grinding, apply adhesive and install rubber flooring tiles or rolls.

6.6 Finishing

Clean and apply floor wax to complete the surface finishing.
