The following accessories form part of the Sikalastic®-260 Stop Aqua (CA) waterprofing system which comprises of the following products:

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

JOB SITE CONDITIONS

Maintain environmental conditions and protect work during and after installation. Comply with trade and industry standards and manufacturers printed recommendations. Turn off all forced ventilation and radiant heating systems and protect the work against drafts during installation and for at least 72 hours after completion. When necessary, use indirect auxiliary heaters to maintain an adequate temperature level in the working area (ambient and surface temperatures). Exhaust temporary heaters to the exterior potential harmfulness to the personal and/or to prevent damage to the work from carbon monoxide emissions. For best results, condition product at a minimum temperature of 18 °C (64 °F) prior to applying. Lower temperatures may result in slower strength development and longer cure times.

Substrate to have adequate strength, load-bearing capacity, be dimensional stable and be permanent dry.

Sikalastic®-260 Stop Aqua (CA) is already premixed and supplied ready to use directly without stirring.

IMPORTANT: Waterproofing is a critical part of an tile installation in a wet area, Sika® strongly recommends that the user reads and understands the following steps before beginning application.

Note: Always apply Sikalastic®-260 Stop Aqua (CA) at 0.5 mm (20 mil) wet thickness at each step.

Pre-treating cracks, gaps in corners and coves that are greater than 1 mm (40 mils)

Fill with SikaLevel®-115 Skim Coat (featheredge up to 13 mm [1/2 in]). For deeper filling and large gaps around drain holes use Sikaset® Plug or Sikascreed®-40. Let dry at least 10 minutes for Sikaset® Plug, 60 minutes (or until completely dry) for SikaLevel®-115 Skim Coat, 5 hours for Sikascreed®-40.

Pre-treating drains

Allow any recently prepared areas to dry. Over a properly sloped floor (note: slope to drain should be 6 mm (1/4 in) per 300 mm (11.8 in) [2%]). Must be of the clamping ring-type with weep holes for setting material application. Drain should be even, level, plumb and fully supported, without movement. Apply a liberal coat of Sikalastic®-260 Stop Aqua (CA) with a clean paint brush around and over the bottom drain clamping ring. Promptly position Sikalastic®-260 Stop Aqua (CA) Floor Patch in the freshly applied. A toilet flange can be treated in the same manner.

Pre-treating substrate to wall transitions, wall to wall transitions, inside or outside corners (for shower bases or curbs)

Allow any recently prepared areas to dry. Apply a liberal coat of Sikalastic®-260 Stop Aqua (CA) using a clean paint brush. Fold Sikalastic®-260 Stop Aqua Reinforcing Fabric in two and promptly position to the substrate to wall or wall to wall transitions into the wet Sikalastic®-260 Stop Aqua (CA). Apply Sikalastic®-260 Stop Aqua Wall Patch (at wall piping), Sikalastic®-260 Stop Aqua Inside Corner Patches or Sikalastic®-260 Stop Aqua Outside Corners Patches into the wet Sikalastic®-260 Stop Aqua (CA). Check and confirm for proper coverage to the Reinforcing Fabric and to the Patch. Once the membrane dries to touch (generally 1 hour), apply a second coat at 0,5 mm (20 mil) wet thickness, “sandwiching” the reinforcing fabric or patches. Total membrane thickness after drying should be between 0.75 mm and 1 mm (30 mil and 35 mil).

Completing general waterproofing

Apply Sikalastic®-260 Stop Aqua (CA) at a rate of one 1 L/m² (50 ft²/US gal) using a paint brush or 10 mm (3/8 in) nap paint roller. Periodically, check the film thickness with a wet film thickness gauge. After drying, cut out the membrane from the drain opening (throat). Locate and punch through the bolt holes. Set the upper clamping ring onto the dried membrane with a continuous bead of Sikasil® GP silicone caulking or similar material about 13 mm (1/2 in) from the drain opening. Depending on the case, pay attention to properly work around the weep holes when applying the sealant so that they can fulfill their function. Bolt the drain collar into place while sealant is still fresh.

Flood testing (in order to confirm the proper performance of the waterproofing before proceeding with the installation)

Although flood testing is not mandatory, Sika® advises that it is good practice to confirm all is in order before tiling work begins. Sikalastic®-260 Stop Aqua (CA) should cure at least 12 hours at 23 °C (73 °F) and 50 % ambient relative humidity. Consult ASTM D5957 Standard Guide for Flood Testing Horizontal Waterproofing Installations for important information. 

Protection

Protect from traffic, dirt, or dust from other trades. Membrane must be covered until the installation of the floor covering. 

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