Where a normal cement based surface would fail, the polymer resin reinforced properties of Tufcon 80 offer many benefits, including resistance to abrasion, heavy traffic and high point loads. For refurbishment and fast-track installation, a pumped version is available.

M10 CEMENT BASED LEVELLING/ WEARING SCREEDS
140 PROPRIETARY POLYMER MODIFIED LEVELLING SCREEDS TO . . . . . . . . . .
A cement based, polymer resin reinforced floor screed designed for use in modern industrial plants where normal cement based surfaces may not be adequate. The screed produces an extremely hard-wearing, dust-free surface capable of withstanding abrasion, impact, heavy traffic and high point loads. It can be laid to new or old concrete and most other substrates without risk of cracking or debonding. It can also be used as a damp-proof membrane and formed into coved skirtings, channel linings, dados, kerbs and to create gradients.
Tufcon Pumped Screed and Tufcon Speed Screed are also available. Consult with Conren Ltd for recommendations and details.
Conren recommend mechanical preparation for most substrates prior to installation of epoxy resin coatings/screeds and offer a range of primer systems to suit most situations.
Where the moisture content in a new concrete slab exceeds 75% RH, e.g. in fast track construction projects, Conren WD Aquatect, water vapour suppressant/primer should be used. Consult Conren for recommendations and details.
Existing surfaces must be clean, dry and free from contamination which can prevent the effective adhesion of coatings and screeds. For heavily oil contaminated surfaces, the concrete should be shotblasted and subjected to hot compressed air (HCA) followed by a holding primer of WD Bonder or WD Aquatect. Consult with Conren for full details.
It is important that movement joints are incorporated throughout the entire floor system and Conren produce a joint system to suit all manner of construction methods, including crack induced/sawn joints and pre-formed expansion joints as well as coved skirting details and other finishing requirements.
Conren will carry out site surveys and offer technical advice on the use and performance of all Conren products. A maintenance range of products is available for end user application.
Consult Conren Ltd technical literature for details. Conren Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.
