Methodology-Epoxy Coating Works for Floor
This methodology specifies the requirement for 2 coats of epoxy flooring in concurrence with the manufacturer recommendations, requirements, and other related detail specifications.
The working area will be barricaded and restricted from the entry of unauthorized personnel.
It will be properly illuminated and necessary warning signs to be installed in the proper location.
All scaffolding activities and ladders for access and egress will be erected by certified scaffolders. All erected scaffolding access and egress will be inspected and tagged prior to use.
The relevant permits to be fully complied with by the working team prior to commencing activity and ensure its validity.
Part mixing is acceptable as per requirements. However, once the pack is opened and not in use this must be tightly sealed with the lid (material to be checked prior to the next usage).
All workers to be involved in the activity will receive proper information, instructions, training, and adequate supervision during the activity. All workers will be briefed as well with the safe system of task and procedure along with the use of proper PPE’s and emergency rules.
Relevant entities which might need protection include any type of work in the area vicinity of work, service access, or discharge path.
The existing area which requires refurbishment must be prepared to ensure a strong adhesive bond between the first coat and the existing concrete area.
Clean the surface by grinding means of heavy-duty substrate grinders to remove the previous coating, laitance, and other contamination such as oil, grease, mortar and paint splashes, etc. (Any sharp edges, protrusions, imperfections, or surface undulations in levels to be ground and made well by the client free of charge.)
Vacuum clean to remove the dust and other loose particles.
Before application, all surfaces must be dry and free from oil, grease, decayed matter, moss or algae growth, and general curing compounds. All such contamination and laitance should be removed by the use of mechanical means.
The surrounding surfaces which are not to be coated but which may be affected by the coat application should be protected.
Fill all exposed blow holes, routed out cracks, etc. with SIKAFLOOR PS up to a rate of 0.1 to 0.2 kg/m² to obtain a uniform surface of texture similar to medium sandpaper.
The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2)
with a minimum pull-off strength of 1.5 N/mm2.
The substrate must be clean, dry, and free of all contaminants such as dirt, oil, grease, surface treatments, etc.
Concrete substrates must be prepared mechanically using abrasive blast cleaning (blasting method) or scarifying equipment
to remove cement laitance and achieve an open textured surface.
Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
Repairs to the substrate, filling of blowholes/voids and surface leveling must be carried out using appropriate products from the Sikafloor, Sikadur, and Sikagard range of products.
All dust, loose and friable material must be completely removed from all surfaces before application
of the product, preferably by brush or industrial vacuum.
Epoxy Paint (Sikafloor 264) Implementation
SIKAFLOOR 264 is a two-part High-build Solvent Free Epoxy Coating. Suitable for use in hot and tropical climatic conditions.
Stir separately components A and B of SIKAFLOOR 264 well with an electric mixer, add the full contents of component B into component A, and mix with a slow speed mixer (300–400 rpm) for at least 2 minutes until a homogeneous mixture is achieved.
Place mixed material into a clean container, mix again for one minute.
Prior to the application of epoxy – SIKAFLOOR 264, the surface should be thoroughly cleaned to remove any traces of dust or other debris.
Apply the primer to the prepared surface prior to utilization of floor putty.
Afterward, apply the epoxy mixed material by roller using the consumption of 0.25 kg/m², taking care to ensure good wetting of the substrate but avoiding puddles on the surface. Allow drying.
Followed by the second coat of SIKAFLOOR 264 using a roller or brush at a rate of 0.25 kg/m² ensuring that the surface is fully covered and that no ponding of the material occurs. The coat should be applied evenly over the floor surface to ensure a regular film thickness.
The minimum interval between the coats is as follows:
Before applying layers of Sikafloor 264
|Substrate Temperature||Minimum Interval||Maximum Interval|
|+10°C||24 hours||3 days|
|+20°C||8 hours||2 days|
|+30°C||6 hours||1 day|
Freshly applied SIKAFLOOR 264 should be protected from dampness, condensation, and water for at least 24 hours. Due to the nature of the activity, for damages on the finished surface, rectification will be done as per manufacturer recommendation which will depend on the type of damage.
Droppings and other foreign matters on different surfaces will be removed and cleaned immediately after the completion of each application.
Thickness and Application Rate
Effective Covered Area
Sikafloor PS-0.200 kg/m²
Sikafloor 264 (1st coat)-0.250 kg/m²
Sikafloor 264 (2nd coat)–0.250 kg/m²
Types of Damages and Remedies
High spots to be removed by means of grinding by the use of the grinding machines.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or industrial vacuum.
The substrate and uncured floor must be at least 3°C above the dew point to reduce the risk of condensation or blooming on the floor finish.
Low temperatures and high humidity conditions increase the probability of blooming, thus weather conditions should be monitored always prior to any kind of coating.
Over mixing must be avoided to minimize air entrainment, since pot life of any kind of epoxy to be followed as per technical data sheet thus the area to be calculated prior to mix the material else it will lead to overconsumption or wastage.
Damage area should be found and analyze the root cause for repair, then the area to be repaired should be square cut and repeat the same application procedure, however, due to material property the color difference may occur.

He is in charge of all construction activities. Schedule the site in logical steps and budget time required to meet deadlines. Inspect and review works to monitor compliance with building and safety codes and other regulations.
The Site Engineer will evaluate the number of materials consumed by each trade to be compared against the planned quantity.
A site foreman is responsible for supervising the workers and also doing actual activity. The foreman monitors employees to make sure that the work is done efficiently and within quality standards.
A Chief Surveyor ensures that surveying data are collected and recorded accurately and that all company guidelines are followed by crew members.
The QA/QC Engineer will monitor whether the installation activities are conforming to the required quality otherwise he should notify the Site Engineer should he find non-conformance to the ongoing construction activities.
The Site Engineer should immediately rectify the work to avoid receipt of non-conformance from the quality engineer.
The Safety Engineer will be full-time at the site and will frequently visit all the ongoing tasks. All safety violations and non-conformance of the HSE Plan will be registered and immediate action will be done in coordination with the Site Engineer.
Ensuring that all his Foremen, Team Leaders, and workers are conforming to safety regulations and are Third Party Certified (TPC).
Ensuring that all scaffolds are erected according to scaffold methods.
Note: Site Engineers/HSE staff should have access on-site to civil method statements and risk assessment
Environment and Quality Issues
All precautionary measures will be briefed to all workers prior to commencing the activity.
All waste will be disposed of as per the Construction and Environmental Management Plan, and as per government-approved disposal areas.
Inspection, Test, and Sampling
Request for Inspection and Testing will be submitted prior to and after execution of works.
Quality Assurance Requirements Table
Ensure that work is executed as per approved shop drawing, method statement projects, and records are generated referring to approved ITP.
Best management practices should also be considered which may be stated by product manufacturers or suppliers.
Authority requirements will take precedence over all requirements in case authority approval is to be secured.
For non-authority approval activities, the approved latest specification will take precedence.
It is to ensure that regular toolbox pieces of training-related work quality are conducted and records are maintained.
