Sealing concrete – things you need to know BEFORE you start

Sealing concrete – things you need to know BEFORE you start

You can DIY your driveway, paths, patio, pool area or garage, just as long as you know some simple rules before you start


Sealing is a process and system that you need to understand before you start:

  • Inspect and understand the existing surface and its history of what’s in the substrate (is there previous sealers? They need to be removed first)
  • Knowing the correct sealer to use for the surface (a penetrating sealer will provide an invisible look and will not make it any more slippery for example)
  • Sourcing the best sealant from quality manufacturers (cheap sealers may not last and unsuitable to re-seal over later)
  • Getting quality advice for any specific variations (a contractor or professional sealing shop)
  • The process and all tools to apply the product correctly
  • Cleaning and preparing your surface to accept the correct sealant
  • Application rates and best practice processes – taking into account the best time of the day, rain, heat, wind, moisture content, surface adhesion etc.
  • Careful and consistent application to avoid roll lines
  • Ensuring the surface will not be more slippery than previously
  • Recording and maintaining the surfaces in best condition


Being let down in any area can lead to:

  • Blistering/Delamination
  • Whitening of the surface – often only in patches
  • Excessive bubbling
  • Imperfect application – too little or too heavy
  • The sealant not lasting very long
  • A slippery surface


Why is sealing so important? 

Hard surfaces are low maintenance – not maintenance free! If you want to avoid staining, mould and deterioration of your surfaces you need to seal. Sealing can prevent 99% of water, oil and contamination penetrating the surface which leads to most early deterioration and dirtiness issues in exposed surfaces.


If you really want save money by clear or colour sealing, ensure you get the right advice, tools, products and processes, and apply by the rules, not what you think will work!
