Surface preparation – Uzin
UZIN L3 Gold, smoothing compound is said to be suitable for use in refurbishment projects as it can be applied over old waterproof adhesives residues such as bitumen, if hard, sound and well-bonded to the substrate. It can reportedly be used without a primer in most cases and has a high compressive strength of 25 N.
‘It’s extremely quick-setting and floorcoverings can be installed after two hours,’ says Uzin. ‘It can also be used under a DPM, is easy to sand down and flows exceptionally well.’
The company adds: ‘Owing to increasing regulation regarding duty of care and allergies to latex, Uzin developed Uzin L3 Gold to be free from ammonia and latex and is therefore perfect use in sensitive environments such as hospitals.’
