Patinaetch- Chemical (acid) stain for concrete surfaces

Patinaetch is a unique a mildly acidic water based product that is designed to etch and stain concrete or masonry substrates. Over the years, this product has been tried and tested by thousands of users from many parts of the world. Coming in a range of 7 colors, Patinaech has a proven record of creating a unique touch to any kind of floor. From small floors to large floors, Patinaech can be used virtually everywhere.

  • Ultra Violet (UV) resistant
  • Zero Volatile Organic Compound Content (VOCC)
  • Non-film forming
  • Relatively low price compared with other similar products

How Patinaetch is applied

To use Patinaetch, these steps have been tested and proven to be the best when it comes to its application.

Method 1

  • Carry out an on-site color sample to see which color is the best to use. There are 7 color samples which can be used. However, a combination of these colors can come up with other colors.
  • Sand the surface prior to staining using a floor polisher with 50-100 grit mesh or sand paper. Please avoid the conventional method of acid washing before applying the Patinaetch. This will remove the free lime needed for this reaction
  • Apply the Patinaetch and give it time to dry.

Considerations necessary using this method

  • Ensure the surface is clean and dry prior to application of Patinaetch
  • Do not acid wash the surface before application
  • Sand the surface prior to staining

Method 2

This method entails a simultaneous process of spraying and scrubing the first coat with a nylon broom using a circular motion. The next step is to respray the surface immediately above the first coat.

However, this, method is appropriate for impervious concrete surface.

Considerations for this method

When using this method, it is important to keep a few considerations in mind.

  • Boost the muriatic acid content of the stain to ensure color penetration
  • Maintain a wet edge
  • Do not splash, drip or allow Patinaetch to puddle in joint areas
  • Do not step on the wet surface
  • Apply from bottom upwards when applying vertical surfaces

Factors that affect the outcome of the chemical stain

  • Cement properties and amount
  • Type of aggregates and admixtures used in concrete
  • Concrete finishing methods
  • Concrete age and moisture content when stain is applied
  • Efflorescence
  • Curing methods

Safety precautions when applying Patinaetch

  • It is important to ensure that the following safety precautions are put in mind when using Patinaetch
  • Do not breathe vapor or mist from the compound
  • Close containers after use and store in tightly closed containers in an upright position
  • Keep away from combustible materials and other heat sources
  • Hold eyelids apart when flushing material out using large amounts of clear water
  • If ingested, drink several glasses of water or milk
