Installing Floor Finishes

Special Floor Finish Recommendations

Where loose laid materials, such as carpet, are being installed over Easy Screed, there is no surface preparation require. Please note our recommendations on specific floor coverings as detailed below:

It is recommended that prior to laying a tile floor finish over Easy Screed, the surface should be prepared and primed using PCI Primer G or equivalent acrylic primer as per the requirements of the manufacturers of the adhesive being used. Primer G is available through Gilroy Tiles nationwide (www.gilroy-tiling.ie)Flexible tile adhesive should always be used where underfloor heating has been installed.

POLYBOND, UNIBOND OR OTHER PVA PRIMERS ARE NOT SUITABLE AS A PRIMER WITH UNDERFLOOR HEATING OR EASY SCREED. USING SUCH PRIMERS MAY RESULT IN FLOOR TILES LIFTING OVER TIME.

  • Timber Floors

    Timber floor adhesive manufacturers recommend primers with their respective adhesives. Manufacturers instructions should be followed.

    Our recommendation is the installation of the Brentec MS35P Structural floor bonding adhesive. This is suitable for use directly onto Easy Screed once the moisture content has reached 0.5%. If the moisture content is higher, a sealer may be required such as Soudal Epoxy Sealer EPR-31P prior to installation of the adhesive. Both products are available from www.sealsystems.ie

  • Flat Floor Surfaces/Resilient Floors (Vinyl & Marmoleum)

    Before installation of a resilient/flat floor finish such as marmoleum or vinyl over Easy Screed, there are 4 critical components which should be met:

    1) Sound and rigid construction

    2) Even and smooth surface

    3) Clean surface

    4) Permanently dry surface

Application

SR1 — 3mm High Standard: Special floors

SR2 — 5mm Normal Standard: Normal use in commercial and industrial buildings

SR3 — 10mm Utility Standard: Other floors where surface regularity is less critical

A SR2 floor finish is easily achievable with Easy Screed. To bring the floor to a SR1, some additional work may be required. A class 1 (SR1) floor finish can never be achieved in a single pour. German best-practice for bringing Easy Screed to a SR1 floor finish is to buff the floors 24 hours after installation, using a specialist buffing machine. This requirement is at the discretion of the flooring contractor.

Permanently Dry Surface

Resilient floor coverings can be laid directly over Easy Screed, on the basis that the screed has been allowed enough time to dry fully.

The drying of the screed is critical before installation of vinyl or marmoleum as rising damp can cause problems with the floor finish. To assist with the drying process, it is recommended that the underfloor heating is turned on for 3-4 weeks before installation of the vinyl/marmoleum. The heating should be turned off for 48 hours before the installation begins.

The flooring contractor should always carry out a moisture check on the floor screed before installation begins. It is recommended that a moisture content of 0.5% is reached before installing the vinyl/marmoleum over Easy Screed.

Applications over Easy Screed:

Method A — Standard installation over fully dried floor

Sticking of Marmoleum directly on to Easy Screed is possible. It requires the following actions.

1. Prime the screed

2. Stick Marmoleum directly on the primed subfloor.

It is best practice that the floor is primed before installation of the adhesive for the marmoleum/vinyl.

Method B — If correct moisture content has not been achieved

IT IS ESSENTIAL TO ENSURE THAT ENOUGH TIME IS ALLOWED FOR THE FLOOR TO DRY BEFORE INSTALLING THE COVERING. If this has not been allowed, then additional works will be required over the Easy Screed; including:

1) Installation of a liquid DPM

2) Installation of an additional primer

3) Installation of a smoothing compound

4) Installation of the adhesive
