Overcoating time between primer and Sikalastic® M 800 R refer to selected substrate primer PDS.

On concrete substrate, before applying Sikalastic® M 800 R on Sikafloor®-161 HC or Sika® Primer PW-F allow*

Before applying Sikalastic® M 800 R on Sikalastic® M 800 R allow*:

Before applying Topcoat Sikalastic® U-Coating or Sikalastic 670 TC or Sikalastic®-701 on Sikalastic® M 800 R allow:

*If re-coating times are exceeded or rain falls or dew occurs on the surface of Sikalastic® M 800 R then the membrane must be dried and Sikalastic® P 691 should be applied at consumption of  80 ~ 100 g/m² or Sika® Reactivation Primer should be applied at ~164 g/m² prior to the application of membrane or Topcoat.

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

The surface must be sound, clean, dry, and free from oil and climates grease, loose particles and other contaminants which may impair adhesion
Depending on the material the substrate must be primed or mechanically cleaned. Grinding may be necessary to level the surface. Suitable substrates are such as: Concrete, bituminous felts and coatings, metal, brickwork, asbestos cement, ceramic tiles.

Concrete and Cementitious Screed:
The concrete substrates to be sprayed must be at least 14 days old, dry, free of laitance as well as substances which impair adhesion such as oil, grease, rubber skid marks, paint, or other contaminants. Preparation of the substrate by grit or shot blasting, high-pressure water jetting, grinding, or scarifying is necessary for plain concrete. Prior to application of the primer the bond strength of the substrate must be at least 1.5 MPa.
The substrate to be coated must be protected against rising damp by having a damp proof membrane installed if it is a slab in contact with the ground.
Asphalt (only indoor!)
The asphalt should be cleaned by high pressure water jetting. In mechanically stressed applications the load bearing capacity of the asphalt should be suitable for the intended use and should be shot blasted so that at least 60% of the surface aggregate is exposed. Blisters should be warmed, re-dressed and de-bond tape applied over.
Bituminous Sheeting
Sikalastic® M 800 R can be applied on bituminous sheeting by using special primers. For further details, please consult your local sales office.
Iron / Steel
Iron or steel surfaces should be sand blasted to an SA 2 ½ finish prior to the application of primer.

Dose and mix with suitable two-component spray equipment. Maintain recommended product and hose temperature.
Recomended pressure:
Part A + B 130–180 bar.
Ensure equal pressure of Part A + B. The accuracy of pressure, mixing and dosage must be controlled regularly with the equipment.

Sikalastic® M 800 R is available with the Part A in Grey colors (stir well before use) and the Part B Colorless. When sprayed results in a uniform grey colour which gives the sprayer a visual control of the quality of the mixing as machine faults become immediately obvious. This can reduce costly clean up time and material wastage. Due to the fast reaction it is possible to rapidly build thicknesses from 1.0 to > 6 mm.
Surrounding areas should be protected from overspray by masking off with e.g. polyethylene sheet or paper. Care should be taken to prevent spray mist being carried by wind by erecting suitable barriers. The temperature of the substrate should be min. 3ºC above the dew point prior to application of the membrane.
Primer has to be cured to a ‘tack-free’ state prior to the application of Sikalastic® M 800 R.

Damageable areas (handrails etc.) have to be protected with tape or plastic wrapping.

Waterproofing:
Spray apply Sikalastic® M 800 R with suitable two-component hot spray equipment. Possible suppliers of spray equipment are Gama, Graco, Isotherm, WiWa,Reaku etc.
UV Protection:
One layer of Sikalastic® U-Coating or Sikalastic®-701 is applied either by roller or airless spray.
For more detailed application engineering information pls. refer to the appropriate method statement.

Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
