SILCOR® 1100

Single layer, cold, spray-applied for building deck and basement wall waterproofing Membrane

Description

SILCOR® 1100  is a tough while flexible, seamless, fast and easy to apply structural waterproofing membrane designed for buried application and the protection of concrete structures based on GCP’s (previously Stirling Lloyd) unique ESSELAC® advanced resin technology and extensive experience in the development of coatings for specialist waterproofing. SILCOR® 1100 enables fast return to service and provides long term protection and peace of mind for the building owner. 

Benefits and values

  • Faster, Easier, Tougher, Safer and Long Lasting

Surface Preparation

All surface coating systems are dependent on the quality of surface preparation.

Concrete

New concrete substrates should be a minimum of fourteen days old and constructed in accordance with BS EN 1992. The substrate must be clean, dry and structurally sound. It must be free from laitance, oils and all other surface contaminants. Where the use of a non-structural screed or a lightweight concrete substrate is proposed, contact Technical Services as these materials often have low cohesive strength or retain water in open pores. Please refer CSP (Concrete Surface Profile) by ICRI (International Concrete Repair Institute) for additional guidance on acceptable surface preparation. 

Steel

On steel surfaces all rust, dirt and contamination should be removed to expose bright metal to achieve a surface finish to receive suitable metal deck primer. For compatibility with other construction materials or where additives, cement replacement or curing compounds have been used please consult the GCP Technical Services Department.

Application

Primer

The substrate must be primed with an appropriate GCP primer prior to application of the SILCOR® 1100 membrane. A choice of primers is available depending on the type of substrate and weather conditions. They are usually applied using a brush or roller. Please consult the appropriate datasheets of Primer PA1 for concrete surfaces and refer to datasheets of Primer ZEDS 94 for Metal deck.

Membrane

SILCOR® 1100 is applied in one single coat. 

SILCOR® 1100 can be applied using spray and hand, kindly contact GCP Technical Service for application guideline. 

SILCOR® 1100 Spray Grade is spray-applied in 1.7mm Wet Film Thickness to give a minimum dry film thickness of 1.5mm. The coverage rate will vary with surface texture. It is highly recommended to use Wet Film Thickness gauge to measure the wet film thickness continuously. Please refer to SILCOR® 1100 application guideline for further details. 

SILCOR® 1100  can be foot trafficked or loaded once fully cured. 

SILCOR® 1100 can be connected and fully compatible with GCP PREPRUFE® Pre-applied membranes. SILCOR® 1100 will require a protection layer against backfill when used on vertical retaining wall Kindly contact GCP Technical Services for a connection detail and backfill recomendation. 

SILCOR® 1100 will require a protection or separation layer depending upon design of final finishes when used on horizontal decks, please contact GCP Technical Services for further details.

Coverage

Primer Refer to separate datasheet
Membrane (Spray) Typically 1.9kg/m2

Coverage rates are based on a smooth substrate and will vary with surface texture and porosity.

Cleaning

All tools and equipment should be cleaned with acetone before the material is allowed to cure.
