  1. Unilit FenXA 1

    Unilit FenXA Lime Binder For Site Mixed Lime Screeds & Lime Concrete Floors 25Kg

    £11.54

    newA pure natural hydraulic lime binder designed to be gauged with the correct volume and quality of sand and water to produce in situ floor screeds and lime concrete slabs. 

    This is a truly versatile product, by mixing the binder (FenXA) in varying ratios with sand or aggregate a breathable lime floor slab or screed can be cast on site simply with the addition of water and clean washed aggregate. Quick and easy to mix this allows the general builder the option of casting in situ floors where a vapour open but strong floor is required and where the flexible non expanding nature of lime is beneficial.

     Benefits

    • Inexpensive - very cost effective
    • Breathable
    • Simple and easy to cast no specialist equipment required
    • No need for expansion or slip joints
    • Tested and proven
    • Can be used with underfloor heating
    • Very low soluble salt content
    • Suitable for most floor finishes

     

    IMPORTANT NOTE

    The slaking method used to create FenXA actively reduces the free lime and salt content of the screed or slab,  unlike most other lime products the potential for free lime and salts to effloresce is therefore greatly reduced, this is a key point  to consider installing with solid masonry, flint & chalk or brick walls typically found in older buildings

    When used at a standard ratio of 1:3 allow for 1.8 bags /m2 at 125mm depth for a lime screed

     Price is per 25kg bag
