Substrate Quality

Cement substrates:
New concrete should cure for at least 28 days and have pull-off strength ≥ 1.5 N / mm2;
Cementitious or mineral based substrates must be mechanically prepared abrasive cleaning or with scarification equipment with the purpose of eliminating the surface cream and reaching a rough and open surface;
Loose or friable particles as well as areas of low strength concrete should be completely removed. Surface defects such as bubbles and voids should be completely exposed;
Repairs to be performed on the substrate such as filling joints, bubbles and as well as surface leveling should be performed using products of the Sikafloor®, SikaDur® and SikaGard® lines.
Large imperfections or protrusions should be removed by, for example, sanding.

Fluid evaporation is a natural phenomenon of concrete that can generate bubbles in subsequently applied layers. The moisture content, trapped air content and surface finish of the concrete must be carefully checked before starting any application work. Application of the membrane at descending or stable temperatures may decrease the evaporation of fluids.
Thus, when possible, the application of the primer layer in the late afternoon or evening may be beneficial.
For waterproofing services print the substrate and always use a reinforced system.

Bricks and stones:
Mortar joints must be strong and must be clean carefully. Make localized ribs on joints and print before application of SikaFill® Reflex Pro.

 
Slate, ceramics, etc:
Ensure all slate / ceramic pieces are integral and firmly attached, replace any broken or missing parts. Ceramics vitrified must be sanded prior to priming and subsequent application of the SikaFill® Reflex Pro.

Asphaltic blankets:
Ensure that asphalt blankets are firmly attached mechanically to the substrate. Asphalt blankets should not show any degraded area. Always print and use a fully reinforced system.

 
Bituminous coatings:
Bituminous coatings should not present sticky or unstable areas, areas with volatile mastics, or areas with tar.
 

Metals:
The metals must be strong. Exposed surfaces should be prepared up to a shiny metal surface. Use ribs located on gaskets and fixings.

Substrates of wood:
The substrates and panels of wood should be in good condition, firmly attached or mechanically fixed.

Paints / Coatings:
Ensure that the existing material is strong and firmly adhered. Remove any oxidized layers and use reinforcements located on the joints.
Existing SikaFill® Reflex Pro Systems (Existing Liquid Membranes): Existing SikaFill® Reflex Pro systems must be firmly attached to the
substrate.

Before applying SikaFill® Reflex Pro on the first compound by SikaFill® Reflex Pro diluted with 10% water, you should wait:

* After proper cleaning¹ the SikaFill® Reflex Pro can be repainted with itself at any time.

Before applying SikaFill® Reflex Pro on SikaFill® Reflex Pro, wait until the drying of the 1st coat:

* After proper cleaning¹ the SikaFill® Reflex Pro can be repainted with itself at any time.

¹Assuming all the dirt has been removed and any contamination has been avoided.

Note: The times given above are approximate and may change depending on the specific environmental conditions at the time of application, especially the temperature and relative humidity of the environment.

Method of Application (Please refer to the latest edition of the Execution)
Wait for the primer to dry before applying the SikaFill® Reflex Pro.
For more information about the standby time, refer to the waiting times in this document. Protect areas that may be damaged by with crepe tape (eg door frames).
 

Coating: SikaFill® Reflex Pro should be applied in two coats of approximately 0.7kg / m².
Before applying the second coat, wait for the drying time indicated in table below the waiting times in this document.

Waterproofing of Coverings: SikaFill® Reflex Pro should be applied in set with a polyester non-woven fabric.

1. Apply a primer coat of approximately 1 kg / m2 Sikafill® Reflex Pro in a compliance of approximately 1m.
2. Place the structurant ensuring that there are no blisters or wrinkles. It should ensure a minimum overlap of 5 cm between the different portions of the structuring.
3. structure.Pass the roller directly onto the structurer with the product still fresh to The entire application process should be done while the Sikafill® Reflex Pro still cool, damp on wet.
4. Reflex Pro, in order to leave the structurant completely embeddedIf necessary, apply one coat of approximately 0.1 kg / m2 Sikafill®
5. in this stage, in all places.
6. Repeat steps 1 through 3 to cover the entire area to be waterproofed.
7. After the drying of the coat with the structurant, seal the area applying one more or two coats of Sikafill® Reflex Pro using a approximately 0.7 kg / m².

Sika recommends performing the details before performing the waterproofing of the surfaces. For details follow the procedure indicated in steps 1 to 5

Tools
High Pressure Hydrojet
If there is dust, vegetation, mold / algae or any other contamination in the cover, it is necessary to clean the substrate with high pressure hydrojet prior to application of the system. Any gravel or dirt from should be removed manually or with a brush before use the high pressure hydro-jet.
 

Squeegee
For elimination of rainwater deposited on the roof
 

Electric Mixer
SikaFill® Reflex Pro should be homogenized with an rotation for 1 minute.
 

Solvent resistant short hair roll
Used in SikaFill® Reflex Pro application to ensure a constant thickness.

Thick Hair Roll:
For the application of SikaFill® Reflex Pro in details and penetrations
 

Equipment for airless projection
It should only be used to apply the layers without structuring and primer.
The pump must meet the following requirements:

Substrate primer

The above indicated intakes are theoretical and do not take into account losses of material during the application or as a consequence of the porosity or irregularities present in the substrate, surface level variations, etc.

Before applying SikaFill® Reflex Pro, homogenize the product for 1 minute until a homogeneous mixture is obtained Avoid mixing excessively in order to avoid the incorporation of air into the product.

Application Notes / Limitations

Do not apply SikaFill® Reflex Pro on substrates with rising humidity;

Always apply the system at ambient temperatures and the descending substrate. If the system is applied in rising temperatures bubbles may appear as a consequence of the rising air coming from the substrate.

Make sure SikaFill® Reflex Pro is completely dry and presents bubbles before the application of the sealing layer.

Do not allow the formation of puddles of water during the application of the various coats nor before complete cure of the product. Eliminate any accumulation of water during these periods.

SikaFill® Reflex Pro should not be applied to roofs where they can form points of water accumulation, especially in places where it may occur subsequent freezing of the accumulated water. In regions with a cold applications in roofs with slopes less than 2nd special.

A non-woven polyester structurant may be used as the reinforcing system total or partial over joints and cracks with movement.
The SikaFill® Reflex Pro is not suitable for constant pedestrian traffic. In situations where pedestrian traffic can not be avoided, SikaFill® Reflex Pro should receive a layer of mechanical protection with ceramic, stone or wood.

Do not apply cementitious products (such as mortar) directly on SikaFill® Reflex Pro. Use a separating layer as for example oven-dried quartz sand.

Clean all tools and application equipment with water immediately after use.

The hardened product may only be mechanically removed.
