Crack repair (floor)
Key Facts
Cracks in concrete floors or screeds are as a rule subjected to changing mechanical loads. To adhesively seal the crack, epoxy resins are particularly suitable. ASODUR-K900 is probably the most practical way to simply, quickly and cleanly close cracks in screeds and concrete. We supply the low viscosity epoxy resin based product in a practical squeezy bag – including gloves, screed clips and PE pipe. You have the possibility to mix a heavy duty pourable resin as a closed system by simply squeezing.
1 Opening the cracks
Saw cut the crack or joint lengthways (to approx. half to two thirds to screed depth). At right angles to the crack and at 30 cm intervals cut in10 cm long transverse slots.
2 Cleaning
Remove dust and contamination and thoroughly clean the cut area with an industrial vacuum or similar.
3 Mixing
Carefully open the third segment of the squeezy bag of ASODUR-K900 and take out the gloves and screed clips. Now remove the black cord from the top of the squeezy bag and evenly squeeze the bag for at least 3 minutes. The bag will become warm during this process.
4 Grouting the cracks
Pour the mixed ASODUR-K900 into the prepared cut and fill to half way. As necessary use the PE pipe supplied as an extension.
5 Place the screed clips
Now lay the screed clips provided into the slots.
6 Trowel the cracks
Close off the surface of the crack with a trowellable consistency mortar produced from ASODUR-K900 and quartz sand.
7 Quartz sand
Evenly broadcast quartz sand (grain size 0.2 to 0.7 mm) into the fresh smoothing mortar.
8 Sweeping off
Once cured remove loose sand by sweeping.
