Application:

  • White pigmented and fine-grained primer for the acceptance of mineral coatings.
  • Applicable on lime or lime-cement plasters
  • Outstandingly suitable as adhesion promoting coating on reinforcing mortars and smooth base surfaces for subsequent thin-layer mineral coatings

Characteristics:

  • Water soluble, plasticizer and solvent free
  • Fine-grained structure
  • Equalises the absorbency of mineral base surfaces
  • Universally applicable on mineral and organic base surfaces
  • Contains quartzitic additives for a permanent silicification of subsequent siliceous coatings.
  • Highly water-vapour and CO2 permeable
  • Filling and equalising of fine hairline cracks
  • Optimum bonding bridge

All technical data are characteristic values which have been determined under laboratory conditions on the basis of the applicable test standards. Deviations under practical conditions possible.

delivery-units:

  • Container 25 kg

material-consumption:

  • Approx. 200 – 300 g/m² dependent on base surface condition

Processing:

BASE SURFACES:

  • Suitable base surfaces must be dry, solid, clean and sound. Observe VOB Part C and DIN 18 363, Para. 3.
  • Loose existing coatings: Remove completely.

LOW AND UNIFORMLY ABSORBENT BASE SURFACES:

  • XERAL PRE 02 silicate sealant can be diluted with max. 5% XERAL PRE 01 silicate deep sealant

HIGHLY ABSORBENT BASE SURFACES:

  • Pre-prime with XERAL PRE 01 silicate deep sealant subsequently prime with XERAL PRE 02 silicate sealant
  • Stir thoroughly before use. Dilute XERAL PRE 02 silicate sealant with max 5 – 10 % XERAL PRE 01 silicate deep sealant and apply uniformly with paint roller or brush. Cover self-contained areas with a thin layer uniformly without overlapping and in one pass. Avoid grain nests and roller rims.

DILUTING:

  • Depending on application and base surface condition dilute with max. 5 – 10 % XERAL PRE 01 silicate deep sealant.

TEMPERATURE AND WEATHER CONDITIONS:

  • Do not work below +8°C.
  • Can be worked over after approx. 24 hours at +20°C and 65 % relative air humidity.
  • High air humidity and low temperatures significantly delay the drying process.
  • Clean implements with water immediately after use.
