Concrete preparation
The shared starting point for every resin floor.
Step 1. Identify and test the slab
Map contamination, cracks, joints and existing coatings. Use the moisture test and acceptance limit required by the system. A dry-looking surface or old slab is not proof. A moisture-tolerant primer is not automatically a moisture-mitigation membrane.
- Surface
- Moisture inside concrete
A dry surface does not replace the required concrete moisture test. Step 2. Clean, profile and vacuum
Remove contamination before mechanical preparation. Create the required concrete surface profile, not a polished finish, then remove dust. There is no universal profile, and an acid wash is not automatically equivalent to the specified grinding or blasting.
Before preparationClean and profiledRemove contamination, create the required profile and remove dust. Step 3. Repair without hiding movement
Repair dormant cracks with the specified material. Moving cracks and joints need an approved movement detail; rigid resin does not stop the slab moving. Let repairs reach their required overcoat condition.
Step 4. Check the actual conditions
Measure air, slab and material temperature, humidity and dew point. Keep within the product limits through application and specified cure. In Puerto Rico, account for hot stored material, open doors, rain and overnight condensation.
- Air and humidity
- Slab and dew point
- Material temperature
Check dew-point margin and every product limit, not just air temperature. Step 5. Control dust and chemical exposure
Concrete grinding can generate respirable crystalline silica. Use task-appropriate dust controls and assessed protection. Uncured coatings need SDS-specified skin, eye and ventilation controls. Isocyanate-containing polyaspartics can cause occupational asthma; low odor does not mean harmless. These guides do not cover spraying.
