Application:
- XERAL COM 10 adhesive and bonding mortar is suitable as a bonding bridge to smooth and/or nonabsorbent surfaces for subsequent plastering, as well as a high-performance bonding mortar for the attachment of mineral insulating boards with high densities.
Characteristics:
- Consists of size-graded and dried calcareous or siliceous natural sand, cement and slaked lime
- Contains additives for improved working, bonding and water repellence

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:
- 25 kg/bag
- 42 bags/pallet
material-consumption:
- Water requirement approx. 6 – 6.5 l/25l bag
- Approx. 4.5 – 5.5 kg/m² bonding (with 6 mm teeth)
- Approx. 4.0 – 5.0 kg/m² bonding bridge (with 6 mm teeth)
All consumption figures are dependent on the base surface condition and application method. Determine exact quantities with test application on object.
Processing:
BASE SURFACES:
- The base surface must be clean, dry, solid and sound as well as free of efflorescence and film-forming release agents. The load-bearing capacity of the plastering base must be carefully tested. Where critical surfaces are concerned, carry out a bonding test. Loosely attached residuals of plaster and/or paints are to be removed in any case. Insulating boards with foam skin (mainly XPS boards) are to be roughened all over and be brushed off.
BASIC INSTRUCTIONS:
- Cover or mask vulnerable areas (glass, ceramics, wood or metal etc.) prior to working. DIN EN 13914, DIN 18550 and DIN 18350 as well as German Construction Contract Procedures (VOB) Part C apply for the execution of plastering.
- Clean tools immediately after use.
MANUAL WORKING:
- XERAL COM 10 adhesive and bonding mortar can only be worked manually.
- Mix the contents of the bag with 6 – 6.5 litres of clean water to a suitable working consistency without lumps using an agitator. After a maturing time of approx. 10 minutes thoroughly stir again.
- When used as a plaster bonding bridge, XERAL COM 10 adhesive and bonding mortar is applied all over using a coarsely notched trowel and drawn horizontally. A toothed trowel with teeth of at least 6 mm is to be used. Before a subsequent plaster application the mortar must have completely cured.
BONDING OF INSULATING BOARDS:
- The application of bonding mortar is normally made over the whole area of the insulating boards or base surface using a toothed trowel. Immediately after application of bonding agent, apply the insulating boards by press butting and floating into position whilst pressing firmly onto the base surface. Make certain that positioning is flush and plumb to ensure that a smooth plane façade surface is achieved. Do not get any bonding agent into the butt joints between the boards.
TEMPERATURE AND WEATHER CONDITIONS:
- The freshly worked mortar is to be protected by suitable means from dewatering too quickly in the sun, in the wind and at high temperatures, as well as from exposure to driving rain and the action of frost.
- High humidity and low temperatures can significantly prolong the curing period.
- Do not work with component and air temperatures below +5°C or above + 30°C.
