I live in a 1960s house with a 15 year old kitchen extension. Two years ago in the kitchen we had installed Karndean vinyl flooring, at significant cost given it necessitated a Uzin L3 Gold moisture control layer beforehand. Part of the flooring recently came away and the originally fitter has blamed a 'significant damp problem' beneath, claiming the floor cannot be repaired. It now turns out the kitchen extension was built without a damp proof course. A builder says he can fix the problem by removing the kitchen cabinets, digging to 70cm, adding a DPM and replacing everything. Is there any alternative?! Not only will the cost be a problem, but we have a new baby due next month... If old houses do not have damp proof course, could we not just install ceramic/clay tiles instead?! Thanks for any help.
Look at a product called Ardex DPM 1C. It can be used in properties that don't have an existing DPM BUT that are not subject to water pressure from below. Install it in a sandwich system with Ardex NA above and below. DON'T LET A BUILDER INSTALL IT! The builders solution is the correct way to do it.
I'd want a damp test first to access how much moisture there is before I'd sudgest anything. As Trimmer said if its Water pressure from below then that's a different matter altogether.
Sounds like a water pressure issue, if its just residual moisture in the substrate the L3 Gold Moisture Control shouldn’t have failed if below 90% RH. Once tested if below 90% RH L3 Gold Moisture Control could be re-used or another DPM system.
I just can't justify using L3 gold at all ? It's far to pricey when I can use a water based moisture suppressant up to 95% & then any screed I like for a fraction of the price
What suppressant and what screed would you suggest? I have a 1960s kitchen to floor., was going to use MVS 95 and Ardex NA ... (However, I'm finding it difficult to find a supplier close by)
1960s ? Does it have a DPM under the sub floor? If not you can't use any primer type DPMs. You have to use a epoxy like Ardex DPM1c
