Job done in only 4 to 5 hours.

Step by step guide


The substrate must be prepared as normal i.e. be sound, free from cracks, clean and free from materials which would impair adhesion. Thoroughly vacuum to remove dust.



If the substrate measures 90% RH or below apply one coat of UZIN L3 Gold System primer using a foam roller and allow to dry for 1 hour. If it measures between 91% to 95% RH apply a second coat and allow to dry.



Mix the bag and bottle components UZIN L3 Gold Powder and the UZIN L3 Gold Moisture Control liquid. Once the product is fully mixed it can be applied over the floor using a steel trowel at depths from 3 mm to 5 mm. It is then ready to accept most floor coverings within 2 hours.


Choose a suitable adhesive for installing the floor covering such as UZIN KE 2000 S pressure sensitive adhesive for vinyl, rubber or lino.  UZIN KE 2000 S is low emission and exceptionally reliable with a great coverage of up to 70 square metres.



The work is then complete and the floor covering is protected against residual moisture in the screed. Save time and money with this rapid moisture control system.


* Suitable for use up to 95% RH if the substrate is primed with two coats. Suitable up to 90 % RH with one coat of UZIN L3 Gold System Primer. See the product data sheets for more information.
