Method Statement -Floor Hardener

1.0  OBJECTIVE OF PROCEDURE

This work method statement covers the applying floor hardener at (affected building) for (your project name).

This work method statement provides information concerning method of application to ensure compliance with contract requirements and drawings besides to perform safe working environment and compliance with safety requirements.

2.0  DESCRIPTION

PYEFLOOR HARDENER NS is designed to provide a monolithic abrasion and impact resistant floor finish. It is composed of selected silica quartz aggregates, cement and plasticizer. PYEFLOOR HARDENER NS can be applied onto any concrete or cementatious based substrate.

3.0  SEQUENCE OF WORK

4.0  WORK METHODOLOGY

4.1   Surface Preparation

Base concrete substrate must be fully compacted with a grade of 30N/mm³ and a site slump test of 75 to 100mm. The base concrete shall be stiffened, at an initial setting point, where light foot traffic is allowed and does not leave a maximum of 5 mm deep imprint. However, the timing shall not be too late until the moisture within the concrete is sufficient to hydrate the PYEFLOOR HARDENER NS. Bleeding on the surface is to be avoided.

4.2  Application

1.       Evenly broadcast about 60% of the material onto the base substrate.

2.       Wait until the colour of the PYEFLOOR HARDENER NS darkens from the absorption of the moisture from the base substrate.

3.       Lightly compact the material using a mechanical power floating machine, at a low speed, to prepare the surface for the second application of PYEFLOOR HARDENER NS. Do not overwork the surface at this stage.

4.       Repeat the process again with the balance 40% of the material.

5.       Compact with mechanical power floating machine at a high speed until a dense finish is achieved.

4.3  Curing

1.       Spray apply proper curing compound or use polyethylene sheet.

2.       Polyethylene sheet must be used to protect the floor finish surface in case of rain.

5.0  SAFETY & ENVIRONMENTAL PROGRAMME

5.1  Safety

• All workers shall provide with PPE (Personal Protective Equipment) and shall be worn every time they are entering the site.
• Impervious gloves and barrier cream should be used when handling these products.
• Eye protection should be worn. If accidental eye contamination occurs, wash thoroughly with plenty of water and seek medical advice.
• If the product contacted with skin occurs, it must be removed before curing takes place. Wash out with an industrial skin cleaner followed by plenty of soap & water.
• The Safety Supervisor / Safety Officer shall ensure the workers understand the safety regulations and explain in detail in particular hazards, where the workers are working and the precaution to be taken their safety.

  

5.2  Environmental

• All workers shall educate on good environmental management practices and well-disciplined to environment.
• The garbage bin shall be provided at the working area and Supervisor shall ensure its must be collected regularly and disposed-off at the approved dumpsite.
• Safety team shall ensure that no open burning of construction or domestic wastes is practiced.
• All workers shall ensure that all tools and equipment machinery are in good condition to avoid any oil leakage that could harm to environment.
• Spillage of component products should be absorbed onto earth, sand or other inert material and transferred to a suitable vessel. Disposal of such spillages or empty packaging should be in accordance with local waste disposal authority regulations.
