Exposed System - Chemical Containment or Cooling Tower Areas with Sikalastic - 702/701 SF

Exposed Unreinforced System with Sikalastic - 702/701 SF

Optional Reinforced Systems - 702 or 702/701 SF (local or fully reinforced)***

**Allow each layer to cure before applying the consecutive layer.
***Localized Reinforcement: Prior to applying the specified coating system. install Sika Joint Tape SA or PAREX Synergy Reinforcing Mesh 355 set in the wet base coat of Sikalastic 702 or Sikalastic 702 THX. Center the reinforcement over all laps, seams, cracks, joints and transitions of dissimilar material.

Note:

• For unreinforced system, a substrate evaluation is required
• Approved substrates: Concrete Slabs, Concrete, Cementitious, Metals, PVC
• Sikalastic 702 THX is required for all sloped & vertical surfaces
• Sikalastic 702 & 702 THX must be overcoated within 48 hrs. with Sikalastic 701 SF
• Where slip resistance or walkway is required, broadcast to refusal a min. 16/30 or 20/40 oven dried silica sand into the second 701 SF top coat while still wet

Resistant to many chemicals. Contact Sika Technical Service for additional information.

Beware of condensation.
The substrate and uncured applied membrane must be at least 35.6°F(+2°C) and 5°F above the dew point (air and substrate) to reduce risk of condensation or blooming on the membrane finish.

Refer to the individual Product Data Sheet.

Preconditions

Confirm waiting time to overcoating has been achieved for the previously applied system base layer.

1. If the maximum overcoating time of the base layer is exceeded, prepare the surface of the existing coating using mechanical grinding equipment.

2. Remove dust and contamination from the prepared surface using vacuum extraction equipment.

IMPORTANT
Do not dilute.
RESIN MIXING PROCEDURE
1. Mix Part A (resin) with a mechanical mixer (Jiffy) at slow speed until the colored pigment is dispersed and a uniform color is achieved.
2. Add Part B (hardener) to Part A.
3. Using a mechanical mixer (Jiffy) at slow speed, mix Part A + B continuously for ~3 minutes until a uniformly colored mix is achieved.  IMPORTANT Do not mix excessively.
4. During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing

PRIMER MIXING
Refer to individual primer Product Data Sheets for proper mixing instruction

Detailing

Sloped & Vertical Surfaces
Apply Sikalastic 702 THX as the base resin.

Non-structural Cracks Up To 1/16''
Detail application not necessary. Apply embedment/base resin layer per instruction. Non-structural cracks between 1/16'' and 1/4'' Rout and seal with Sikaflex® sealant. Apply 3'' Sika® Joint Tape SA centered over the crack. Apply embedment/base resin layer per instruction.

Cracks and Joints Between 1/4" and 1'' and above
Consult Sika

Transitions Between Dissimilar Materials
Apply Sika® Joint Tape SA centered over edge or PAREX Synergy Reinforcing Mesh 355 set in a base coat of Sikalastic 702 THX. Apply embedment/base resin layer per instruction.

Base Resin Layer
Apply mixed Sikalastic® -702 using a notched squeegee, roll with a spiked pin roller and allow to cure.
Cure a minimum 6 hours at 70 °F and 50 % R.H. or until tack free before top resin layer. Keep clean and dry and apply top resin layer within 48 hours. If window of 48 hours is exceeded but less than 7-days clean with non-sudsing detergent, clean water rinse, and allow to dry prior to application of Sika® Reactivation Primer. If 7 or more days has lapsed a light surface grinding is required. Surface must be clean and dry prior to applying Sika® Reactivation Primer and top coat resin.

Base Embedment Layer with PAREX Synergy Reinforcing Mesh 355
Apply mixed Sikalastic® -702 using a notched squeegee, roll with a spiked pin roller, embed the Parex reinforcement into wet base coat and back roll or trowel to fully encapsulate the reinforcement, allow to cure.
Cure a minimum 6 hours at 70 °F and 50 % R.H. or until tack free before top resin layer. Keep clean and dry and apply top resin layer within 48 hours. If window of 48 hours is exceeded but less than 7-days clean with non-sudsing detergent, clean water rinse, and allow to dry prior to application of Sika® Reactivation Primer. If 7 or more days has lapsed a light surface grinding is required. Surface must be clean and dry prior to applying Sika® Reactivation Primer and top coat resin.

Aggregate Surfacing
For foot traffic and cementitious overburden adhesion key. Supplemental aggregate surfacing is required for all applications that will experience direct foot traffic such as balconies, terraces, walkways, and plazas. It is also recommended for areas that experience maintenance foot traffic. Aggregate surfacing is applied in a supplemental resin layer after the Sikalastic membrane has been installed. Aggregate is not applied into the roofing/waterproofing resin top coat.

Full Broadcast and Seal Option
The Full Broadcast and Seal option is intended for use for applications where both enhanced slip resistance and physical protection of the roofing membrane is required. Apply Sikalastic®- 701 SF resin at 10-12 mils wet film thickness to the installed, cured membrane system. While the supplemental resin application is still wet broadcast to rejection (full broadcast/beach) with kiln dried, iron free aggregate. Remove excess aggregate after cure. Seal with an additional coat of Sikalastic 701 SF (10-12 mils wft).

Aggregate Selection
Use clean, rounded or semiangular, oven dried quartz sand with a minimum hardness of 6.5 per the Moh’s scale. It should be supplied in prepackaged bags and free of metallic or other impurities. The following size gradations are recommended: ▪ 16/30 or 20/40 mesh for pedestrian traffic systems ▪ 30/60 for adhesion key, cementitious overlay.

Overburden Application
Sikalastic®-702 is used as the waterproofing layer under a wide range of overburden materials. Depending on the overburden type, different surfacing, drainage, and protection layers may be required.

Protected Membrane
Assemblies install Sika drainage mat over the Sikalastic®-702 or Sikalastic®-702/701 SF waterproofing system prior to adding the extruded polystyrene insulation layer. No aggregated membrane surfacing is required.

Concrete Pavers with Pedestal Supports
Install Sika drainage mat over the Sikalastic®-702 or Sikalastic®-702/701 SF waterproofing system to provide additional protection of the membrane under the pedestal supports. 



Cementitious or Thin-Set Adhesive
A full aggregate broadcast surfacing is required to provide an adhesion key for the tile adhesive. Apply a supplemental 20 wet mils of Sikalastic®-702 waterproofing resin, followed by a full broadcast of 30/60 kiln-dried sand to refusal, typically 40-50 lbs./100 sf. Remove all loose sand once resin has cured. Do not seal the aggregated surface.

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
