How to Choose Seamless, Resinous, or Polished Concrete Flooring

It is essential that, in the design and construction stages, there should be full consultation with the Duraamen representative and/or the specialist flooring contractor to ensure that the product to be selected is entirely suited for the conditions both during application an in subsequent service. Consideration should therefore be given to whichever of the following are applicable:

  1. Intended use of the flooring including the type, extent and frequency of trafficking
  2. Type of loading, static or dynamic, and severity of impact
  3. Details of all chemicals, including those used for cleaning or sterilizing, which could come into contact with the floor, and extent, frequency and temperature of spillage
  4. Temperature that the flooring is required to withstand in normal service or as a part of the cleaning operations and whether exposure is by radiant or conductive heat or by direct contact
  5. Color, uniformity and retention, aesthetics and decorative effects
  6. Extent to which flooring will be exposed to direct sunlight or ultra-violet light
  7. Compliance with hygiene or food industry requirements
  8. Special requirements such as slip resistance or static controlled characteristics
  9. Expected life of the flooring
  10. Thickness of flooring to be installed
  11. Time available for the application and curing of the flooring
  12. Age, specification where known and nature of the base, including information about any previous use of the floor which could affect adhesion, and any preparatory treatment required
  13. Health & safety and environmental issues during application and in service

Selection Parameters

Factors influencing the selection of a flooring system include:

  1. Type and degree of traffic
  2. Temperatures to which flooring will be exposed
  3. Nature and duration of any chemical contact with the floor
  4. Wet or dry service conditions
  5. Slip resistance requirements
  6. Ease of cleaning (include hygiene requirements)
  7. Time available for application and cure of flooring
  8. Prevailing site conditions at time of installation
  9. Cost

Duraamen Flooring Systems are classified into eight specific types

Floor sealers Applied in two or more coats. Generally solvent or water borne LD Up to 150 µm Perdüre A01, Perdüre A03, Perdüre E32, Perdüre U46/U45
Floor coating Applied in two or more coats LD/MD 150 µm to 300 µm Perdüre E02, Perdüre E10, Perdüre U46 / U45
High build coating Applied in two or more coats—Generally solvent free MD 300 µm to
1000 µm
Perdüre E20, Perdüre P70
Multi-layer flooring Aggregate dressed systems / cementitious system MD/HD > 2mm Sgraffino, Endüra, Lümiere
Flow applied flooring Self leveling or self smoothing surface (cement or resin based) MD/HD 2mm to 3mm Pentimento, SLE, Kwörtz
Resin Screed Flooring Trowel finished, heavily filled systems (cement or resin based) MD/HD

> 4mm

Päram 5500, SLE (T), Kwörtz,
Heavy duty flowable flooring Having a smooth surface HD/VHD 4mm to 6 mm Päram 5500, SLE (T), Kwörtz
Heavy duty resin flooring Trowel finished, aggregate filled systems, effectively impervious throughout thickness VHD

> 6mm

Päram, 5500, SLE (T), Kwörtz

LD - Light duty - light foot traffic, occasional rubber tyred vehicles

MD- Medium duty - regular foot traffic, frequent fork lift truck traffic, occasional hard plastic-wheeled trolleys

HD - Heavy duty - constant fork lift truck traffic, hard plastic wheeled trolleys, some impact VHD - Very heavy duty - severe heavily loaded traffic and impact

durability of decorative—resinous flooring systems

In very general terms the service life will be proportional to the applied thickness of the flooring system. However, many operational factors will directly affect the performance including the severity of trafficking (wheel type and loading), the frequency and efficiency of cleaning, mechanical handling abuse and impact, etc. In most industrial facilities there will be a variety of situations for each of which a different type of decorative-resinous flooring will be most appropriate. Conversely there will be areas where some types are completely inappropriate.

Generally, Types 1 to 3 are suitable only for pedestrian or commercial use or the lighter industrial situation. Where there is regular or heavy fork lift traffic the thicker floorings of types 4 and above will be most suitable. For the heaviest usage, particularly where there is the possibility of significant impact damage, then the flooring of Type 7 and 8 will be appropriate.

Premature failure of the coatings of types 1 to 3 can occur if grit or metal swarf is not cleaned away and is then ground into the surface under the action of traffic. A thicker type of flooring would then be required.

The most appropriate flooring for any situation will depend upon the particular conditions to which it will be subjected, and the choice should be made in discussions between all the interested parties, including client, architect, engineer, contractor and Duraamen technical representative.
