Product Details
Composition
Modified acrylic resin dispersion
Shelf life
12 months from date of production
Storage conditions
Store in undamaged, unopened, original sealed packaging in dry conditions at temperatures between -10°C and +40°C. Protect from direct sunlight, heat and moisture. If frozen, SikaCeram® P 302 should be slowly thawed and stirred thoroughly.
Density
~1.0 g/l (25°C)
Application
Mixing ratio
Can be used as Undiluted or Diluted with water in 1 : 1 ratio, depending from the substrate type.
Ambient air temperature
+5°C min. / +40°C max.
Substrate temperature
+5°C min. / +40°C max.
Tack free time
Walkable after 30 – 60 minutes, at +23°C and 50 % relative humidity.
Note: Times are approximate, subjected to substrate absorbency and will be affected by changes in ambient conditions, particularly temperature and relative humidity. Higher temperatures reduce, lower temperatures increase the times given.
Waiting time to overcoating
Overcoating by itself: Min. 30 minutes, at +23°C and 50 % relative humidity.
Note: Times are approximate, subjected to substrate absorbency and will be affected by changes in ambient conditions, particularly temperature and relative humidity. Higher temperatures reduce, lower temperatures increase the times given.
Drying time
Subsequent application: Min. 60 minutes, at +23°C and 50 % relative humidity.
Note: Times are approximate, subjected to substrate absorbency and will be affected by changes in ambient conditions, particularly temperature and relative humidity. Higher temperatures reduce, lower temperatures increase the times given.

Undiluted SikaCeram® P 302 |
Gypsum based substrates, anhydrite screeds, mastic asphalt screeds, xylolith screeds, screeds with old adhesive residues. |
80 to 150 ml/m² |
|
Diluted SikaCeram® P 302 (1:1 with water) |
Absorbent mineral substrates, e.g. concrete, sand-cement screeds, gauged renders, aerated concrete, limestone or similar. |
1st coat: 100 to 200 ml/m² 2nd coat: 50 to 70 ml/m² |
Note: These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, wastage or any other
variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions.
SUBSTRATE PREPARATION
The substrate must be sound, clean and able to bear weight. Oil stains, bond-breaking residues such as waterproof adhesive residues, cement paste, and dirt must be thoroughly removed. Newly applied cement screeds must not have a moisture content above 4 %, ground anhydrite and/or gypsum-based screeds not more than 0.5 % (measured with CM meter).
APPLICATION
Priming and strengthening of gypsum-based substrates, anhydrite, mastic asphalt and xylolith screeds as well as screeds with old adhesive residues (not suitable with water soluble adhesive residues, e.g. sulphite liquor adhesives), as follows:
- Stir SikaCeram® P 302 well prior to the application.
- Apply a sufficient quantity of undiluted SikaCeram® P 302 by brush or float to achieve a uniform coat. Avoid puddles forming!
- Check strengthening and curing by scratching the surface. Do not apply tile adhesive, wallpaper, paint, plaster SikaLevel®-528, SikaScreed®-538 until SikaCeram® P 302 has completely cured.
Priming and strengthening of absorbent mineral substrates, e.g. concrete, sand-cement screeds, gauged renders, aerated concrete, limestone or similar, as follows:
- Stir SikaCeram® P 302 well, dilute in 1 : 1 ratio with water and mix thoroughly.
- Apply a sufficient quantity of diluted SikaCeram® P 302 by brush or float to achieve a uniform coat.
- In case of very absorbent substrates it is recommended to apply a second coat of SikaCeram® P 302, diluted 1 : 1 with water to achieve a more intensive strength and to avoid bubbles forming. Do not apply the second coat until the first one has completely cured.
- After the primer has cured (scratch proof) apply tile adhesive, wallpaper, paint, plaster, SikaLevel®-528 or SikaScreed®-538.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
