Dear Sirs I have a terrace which has cracks and it is leaking to the flat below when rainting. My builder recommended the Sikafloor 420 product. We just wonder if it is worth using the fibreglass mat in between so that the waterproofing is extra strong. The proposed layers: Sike primer (the substate is concrete) Sikafloor 420 Sika fibreglass mat Sikafloor 420 Would that be suitable for the terrace and also for the steps? Kind regards
Thank you for the enquiry, please can you provide more information on the terrace including what it is made of along with pictures to [email protected] so we can assist with a recommendation.
