Repairs to Concrete Floors
Once a repair goes beyond surface dusting or a fine crack, it needs a structural repair mortar rather than a cosmetic fix. Here's how Samson approaches more significant floor repairs, and the products behind them.
When the damage is more than cosmetic
For more significant repairs, chip out the damaged area and use PatchMortar, or MicroConcrete for repairs over 10mm thick, bonded with P3 Primer to ensure the new material stays put.
Resurfacing rain-damaged or worn slabs
RampSkim is a unique product suitable for 4–8mm concrete resurfacing, for example where rain-damaged slabs need a skim repair. It's bonded using P3 Primer and, depending on requirements, doesn't need to be smooth-trowelled: it will naturally provide a satisfactory surface for parking decks and many other applications.

Getting technical support
For technical data sheets and installation processes, request a Samson method statement for site instruction. If the damage looks like more than dusting or a fine crack, contact Samson directly for technical guidance before you commit to a repair method.
