Anhydrite Screed Primer, Edge Strip & Accessories

Primer:

Anhydrite screed always requires priming prior to sticking down any floor covering such as tiles, wood or vinyl. This is to stop the screed from sucking the moisture out of the floor adhesives too quickly and causing them to fail.

It is essential that you use an anhydrite compliant primer, as primers for alternative types of screed will react with the screed and will cause the failure of your floor coverings.

We recommend and supply Uzin PE360 primer as we have found it to be easy to use, and very reliable.

We stock 5 litre drums which will each provide up to 50m² of coverage.

Cost per drum is £38.00 (ex VAT). There is no delivery charge if this is supplied at the time of supplying the screed.

Screedflo edge strip:

Regardless of the type of screed being used, an edge strip should always be used around all walls, stairs, and pipes that the screed will come in to contact with. It is required for a number of reasons:

  • To allow for expansion of the screed
  • To prevent transmission of sound between rooms
  • To prevent spread of fire at the base of timber walls

Most edge strips were developed for use with masonry walls. The Screedflo edgestrip is unique in that it was specially developed to be used with both masonry and timber walls. This means that it has much better acoustic and fire performance than other edge strips.

Made from high quality, closed-cell, cross-linked foam, the Screedflo edge strip offers a number of benefits to the self-builder:

  1. The foam used is much stronger than alternative edge strips, making it much easier to use on site, and reducing wastage.
  2. Cheaper materials cannot expand again once they have been compressed by the screed for the first time. Consequently, if the screed shrinks again when it cools, a gap can be left around the perimeter of the floor, allowing sound transmission between rooms. The unique closed-cell structure of the Screedflo material means that the foam expands or contracts along with the screed. This minimises sound transmission as it prevents these gaps from occurring.
  3. Having been developed for use with timber framed walls, the Screedflo edge strip is made from fire resistant foam. This helps to prevent the possibility of fire transmission at the base of the plasterboard on timber walls.
  4. A quick peel adhesive strip ensures fast and easy installation.
