An epoxy risen floor coating system has the ability to withstand pressure from heavy loads and objects. Because of this
Method statements are not always easy to write that is why the services of a quality engineer are sometimes required in the process of writing it. Are you trying to prepare a method statement? Here are the things you should do in preparing a method statement for an epoxy risen floor coating system.
1. Title
Method Statement for Epoxy Risen Floor Coating System
2. Purpose and Scope
This method statement is for the purpose of painting the concrete floor with epoxy resin coating system.
The method statement will particularly cover the floor of the hangar and warehouse, first floor of the working areas.

6. Methodology
6.1 Delivery of materials to the Site
6.1.1. The materials will be transported to the site by the paint factory and the materials must meet the standard requirements meaning that the supplier adhered to the 50kph speed limit and 11km distance while transporting it.
6.1.2. When the materials arrive the site, the security personnel on the ground will inspect the materials thoroughly and then the materials are escorted to the storage area by well-trained flagmen
6.2 Materials and handling
6.2.1. The contractor must ensure that the storage is close to the installation area and the subcontractor must ensure that the materials are delivered on time to avoid unnecessary delay. The units in the construction site should be arranged in such a way that loading, transporting and unloading will flow according to the standard requirement.
6.2.2. The epoxy coating materials must be transported using secure trucks and delivered to the site at the right time. Also, it must be offloaded using the right equipment or it can be offloaded manually according to the site requirement. After offloading it is stored in a secure storage area which should be close to the installation area.
6.2.3. The epoxy coating material is best stored in a well-ventilated storage room that is away from direct sunlight.
6.3 Substrate Conditions & Surface Preparations
6.3.1. Make sure that the reinforced concrete slab on the ground surface is dry and the edges of the surface are finished. The strength of the concrete must be greater than 25N/mm2 and the moisture content should be less than 5% making sure that it adheres to the manufacturer’s standards.
6.3.2. Before surface preparation commences fully, the contractor must ensure that the area is free from any form of traffic or activity.
6.3.3. The surface must be roughened using a light grinding machine or vacuum, this also heals the open pores on the concrete surface.
6.3.4. Remove any contaminant on the surface before any other preparation process is done, contaminants like oil and grease
6.3.5. Repair and fill up any minor surface defect using epoxy putty. Defects like cracks, holes, and others must be filled up according to manufacturer standard.
6.3.6. After floor preparation, the area must be cleaned by vacuum to remove any debris or dust that is left behind.
6.3.7. Cover the free edges of the surface using a 50mm masking tape.
6.4 Application of Top floor
6.4.1. Clean substrate again to remove dust and loose materials
6.4.2. Topcoat film is prepared by stirring Base A to disperse any settlement, after which Hardner B is added to Base A and mixed slowly for about 2 minutes making sure that air does not get into it, after mixing, transfer to another container and mix again for 30 seconds.
6.4.3. After mixing, apply the top coat film on the prepared surface using shirt hair rollers. Application speed should be 0.25kg/m2.
6.4.4. After application, the top coat must be protected using a polyethylene sheet for a period of 24 hours before allowing foot traffic. Vehicle traffic should be allowed five days after application.
6.4.5. The subcontractor should inspect the floor after coating before the main contractor. After the main contractor’s inspection, the consulting engineers will then perform the final inspection. All of this is to make sure that the installation meets the requirements.
6.5 Demobilization
6.5.1 After the work is completed, every equipment must be cleared out of the surface. Making sure that all of them are still in a working state.
7. Safety
7.1. Make sure that the workers involved in the installation of the epoxy resin floor coating are experienced and well trained.
7.2. Every stage of the installation must be supervised properly. Check all the routes of material transportation and remove any form of obstacle that could cause accidents. There should be frequent cleaning during working hours.
7.3. Every equipment used must be maintained in accordance with legal requirements.
7.4. Electrical connections should be handled by qualified and approved electricians.
7.5. The workplace must be barricaded and well protected to prevent unauthorized personnel.
7.6. A work permit must be issued to every person by the main contractor before work starts on the site.
7.7. Appropriate loading and offloading equipment should be provided by the contractor. All the equip, eats should be certified and handled by a qualified operator.
7.8. Keep a material safety data sheet to ensure that materials star handled well especially chemicals. Major spill kit available and personal protective equipment must be made available to every personnel must be worn at all times.
8. Other things you must handle
8.1. Land contamination: Make sure you remove every contaminated soil and dispose properly in line with the Construction Environmental Management Plan. Make sure that every equipment is free from contamination before it is used on daily basis.
8.2. Dust: Dust infested vehicles must be cleaned properly before use.
8.3. Noise: The noise level of the work area must be monitored from time to time. This ensures that every process is carried out within the permissible limit of noise. If noise rises above permissible limit, ear plugs must be employed to achieve balance. Noise level should be monitored at regular intervals.
That’s the process you must cover when preparing a method statement for an epoxy risen floor coating system.
