Primers Generally
Primers are not normally required for the Sikalastic 612 coating system. For porous or
2
2
irregular surfaces typically allow an extra initial coat of 0.25 0.3L/m (circa 0.4kg /m )
if necessary.
Dusty friable surfaces will benefit from sealing with the Sika primers shown below.
However this is not a substitute for achieving a sound surface and adhesion quality
under these circumstances is limited by the strength and condition of the substrate.
All primers shall be coated within 24 hours or as soon as individual data sheets advise
to avoid atmospheric or physical contamination.
See also table below for specific substrates.

Substrate Treatment
(continued)
Bituminous felt
Bitumen felt has variable softening points and additives many are and remain soft or
volatile. Use full reinforcement! Ensure that Bituminous felt is firmly adhered or
mechanically fixed to the substrate. Use strips of e.g. Sikalastic Fleece 120 or

Instructions
Application Method
Prior the application of Sikalastic -612 the priming coat if used must have cured
tack-free. For the Waiting Time / Overcoating please refer to the PDS of the
appropriate primer. Damageable areas (handrails etc.) have to be protected with
tape or plastic wrapping.
Roof Coatings: Sikalastic -612 is applied in two coats. Prior to the application
nd
of a 2 coat the indicated waiting time in the table below Waiting Time /
Overcoating shall be allowed.
Sikalastic Fleece 120. Over coating of bitumen felt has to be full reinforced!
2
1. Apply first coat of approximately 1.3 L/m of Sikalastic -612 Work only so far
in advance that the material stays liquid.
2. Roll in the Sikalastic Fleece-120 and ensure that there are no bubbles or
creases. Overlapping of the fleece a minimum 5 cm and ensure overlaps
are sufficiently wet to bond.
3. The roller may require only a little extra material to keep wetted but no
further significant material needs to be added at this stage.
4. After the coat is dry enough to walk on, seal the roof area with second coat

Mixing
Application Method /
Tools
By brush:
With a soft bristle brush.
By roller:
With a solvent resistant, non-fuzzy roller.
By spray:
Airless spray equipment, for example: piston pump Wagner EP 3000.
(pressure: ~ 200 - 250 bar, nozzle: 0.38mm - 0.53mm, angle: ca. 50 - 80).
Ensure sprayed film will hold on the pitch of the surface at the desired thickness
without running. Spray more thinner but coats if required
For Reinforcement or Waterproofing systems apply 1.3 L/m2 of coating and
whilst wet lay on the Sikalastic Fleece 120. Apply gentle pressure with a loaded
roller so the Fleece is saturated and free from entrapped bubbles.
Cleaning of Tools
Clean all tools and application equipment with Thinner C immediately after use.
Hardened and/or cured material can only be removed mechanically.
Cleaning of Hands/Skin
Immediately wash with soap and water or use Sika Hand Wipes.
Potlife
Sikalastic -612 is designed for fast drying. Therefore the material will cure
particularly quickly in high temperatures combined with high air humidity.
Even in the tin the material will begin to cure once exposure to air do not
attempt to re-seal and re-use.
Skin formation starts after approx. 1 hour (+20C / 50% r.h.).

Notes on
Application/Limitations
Maximum
After four days the surface has
to be cleaned and primed with
4 hours
Sikalastic -612 is not suitable for permanent water immersion or inverted roof
structures.
Vertical or steeply pitched surfaces may require an additional application to build
required thickness.
On substrates likely to exhibit outgassing, ensure substrate is thoroughly dry and
apply during falling ambient and substrate temperatures. If applied during rising
temperatures pin holing may occur from rising vapour. In very severe case
Sikalastic Concrete Primer may assist.
Product must be used in conjunction with a safe system of work. Ensure an
adequate assessment of all site risks has been conducted prior to work
commencing. Refer to the product safety datasheet for further guidance.
Sikalastic 612 may exhibit slight chalking at the surface do not use run off
water for live fish tanks, etc.
Material begins to react with air once opened. Tight fitting lids may also damage
on opening. It should be planned ideally to use all material in one use. Resealing
for use at a later date is not possible. Opened unused material may thicken and
gas if used later.
