Sika MonoTop®-159 Reno WP Screed

(former Davco® Reno Waterproof Screed)

HIGH QUALITY WATERPROOF FLOOR SCREED

Sika MonoTop®-159 Reno WP Screed is a high quality non-toxic cementitious waterproof floor screed that is specially formulated with recycled material for reduced embodied carbon footprint.  Sika MonoTop®-159 Reno WP Screed is a single component and cost-effective waterproofing system that provides integral waterproofing by forming a hydrophobic layer within the screed.
By simply adding water and mixing with a mechanical mixer, Sika MonoTop®-159 Reno WP Screed yields a homogeneous mortar paste that gives good workability when applied for the levelling of rough and uneven concrete floors.  

  • Formulated with recycled material to minimize environmental footprint.
  • Prepacked to ensure good consistency, good quality and convenience in handling and transportation.
  • Waterproof properties of screed provides a hydrophobic barrier to water seepage.

Application steps

SURFACE PREPARATION

Receiving floor surfaces should be thoroughly cleaned of all dirt, dust and impurities, which may affect adhesion. Conventional curing compounds should be removed prior to application of Sika MonoTop®-159 Reno WP Screed. Prior to the application, a slurry bonding coat should be applied to ensure good adhesion.

MIXING

Add 40 kg of Sika MonoTop®-159 Reno WP Screed to approximately 4.2 - 6.4 litres of water. Mix with a site drum mixer for 3 - 5 minutes until desired homogeneous mix is achieved. Ensure that it is free of lump before use.

 

APPLICATION

Ensure that the substrate is damp and clean without any ponding water.

A bonding slurry coat should be applied before screeding and it consists of 1 part of SikaLatex®-88 Reno mixed with approx. 0.5 to 1 part of Sika MonoTop®-159 Reno WP Screed. A site trial can be conducted if necessary to ensure the consistency of the slurry coat is suitable. The mixed Sika MonoTop®-159 Reno WP Screed mortar is then poured onto the slurry coat wet-on-wet after about 30 minutes. Compact and finish the screed in accordance to standard practice using a suitable float or trowel.

CURING TREATMENT

In hot ambient temperature, the screed should be cured with water spray for at least 3 days. It is important to protect the product from direct sunlight and wind during application and curing. This is to prevent rapid dehydration or desiccation (excessive moisture loss).
