MVN DURAFLOOR

METHOD STATEMENT

Concrete quality

New concrete should be formulated with a minimum cement content of 300 kg/m³ of concrete and with an aggregate suitable for the intended purpose. Plasticizers should be included to improve workability. Concrete air entrained must be lower than 3%. Stting time of concrete is important figures helps to decide the appropriate moment should be carried out the hardener sharking. The concrete mix-design should be evaluated by carrying out concrete trail-mixes before approve

MVN DURAFLOOR should be applied As soon as the substrate of concrete has reached plasticity (after bleeding, but before setting begins), as soon as it will support the weight of a man (the foot-print test). This will normally be after 4-12 hours depending on the weather conditions.

MIXING AND APPLICATION

Manual sprinkling

For optimum results sprinkling should take place in two stages when applied manually:

• For the first sprinkle coat MVN DURAFLOOR should be spread evenly on the surface at a rate of 2 to 3kg/m². Once this application of powder has absorbed all of the moisture, it should be floated using hand trowels for edges and corners, and power trowels for the main surface
• Immediately after the first power float is complete, the second manual application of MVN DURAFLOOR  should be spread over the surface at a rate of 1-2kg/m². Once this application of powder has absorbed all of the moisture, it should be floated using hand trowels for edges and corners, and power trowels for the main surface
• A smooth,  hard finish is then achieved by usd of a power float equipped with finishing blades. For light colors stainless blades should be used.

Mechanical spreader

• Mechanical spreading requires only a single pass. Using a mechanical spreader MVN DURAFLOOR  should be spread evenly on the surface at a rate of 3 to 5 kg/m²
• Once this application of powder  has absorbed all of the moisture, it should be floated using hand trowels for edges and corners, and power trowels for the main surface
• A smooth, hard finish is then achieved by use of a power float equipped with finishing blades. For light colours stainless blades should be used.

Fresh topping

• MVN DURAFLOOR is mixed with water at a rate of 3 to 3.5 litres per 25 kg bag in a suitable mortar mixer until a homogeneous slurry is obtained
• The slurry is then poured onto the surface of the concrete at a minimum rate of 7 to 8 kg/m² and levelled to the required thickness using straight edges
• The should the be floated using hand trowels for edges and corners and power floats for the main surface
• A smooth, hard finish in then obtained by use of a power float equipped with finishing blades.

Curing

Use curing agent to immediately cure after the finishing operation is complete

It is essential that the curing process be well advanced before the floor is put into service. The following delays must be observed:

• Pedestrian traffic:             7 days
• Light traffic:                     14 days
• Full use (fork lifts, etc.):  28 days

Cleaning

All tools and equipment should be rinse with water immediately after use, clean and remove all traces of grout.

HEALTH AND SAFETY

During use, avoid inhalation of dust and contact with the skin and eyes. Wear suitable clothing, gloves, eye protection and respiratory protective equipment.
