Surface Measuring Instruments

An Ra meter provides a scientific measurement of a concrete floors (surface) texture, determining its smoothness to the micro-inch or micrometre.
By using these measurements, you’ll have an accurate understanding of a concrete floors roughness at each stage of the polishing process and by referencing the ST-115 Surface Textures Chart, know will how to proceed to obtain the agreed result. 
This allows quantifiable, repeatable results in accordance with the American Concrete Refinement Standard ST-115.

• Simple to use.
• Eliminates the need to go back steps to remove missed scratching.
• Confirms the correct surface has been achieved for each stage of polishing.
• Allows the polishing process to be completed more efficiently with conclusive standards achieved.
• Used in conjunction with Absolute Floor Solutions System & American ST-115 Standard.

A Slip Meter provides a simple method of testing a floors static Co-Efficiency for compliance against slip hazards. A slip meter whilst can be used in wet or dry conditions, it is often used to confirm a finished floor surface is slip resistant when it's wet.

NZ's slip compliance value is defined as having a surface that gets a Co-efficient of Friction (CoF) reading greater than 0.4 or a Slip resistant value (SRV) of 39 or greater.

Seals and Stain Guards are available to protect a finished concrete surface. Their effect on the surface for slippage, gloss, UV stability, durability and wearability need to be considered
