Suitable Substrates

Wood component parts (dimensionally stable, limited stable or unstable).

Defects on wooden parts (rottenness/decay) indicate wetness due to dammed-up water. They are normally caused by structural defects which must be repaired before using Capadur Repair AS. 
Histolith® Sanopas-Holzrisspaste can be used instead, when timber framing has to be repaired considering aspects of care and preservation of ancient monuments.

Maximum permissible wood moisture content: 15 %.

Substrate Preparation

Check all wood component parts very thoroughly for structural defects and remedy deficiencies properly in a technically correct manner.

Shape/mill all cracks and open timber joints min. 5 mm wide and 5 mm deep. Completely remove all decomposed or insufficiently stable wood by shaping/milling or sawing.
(Suitable tools: Fein Multimaster or spherical-head shaper, delivered by miscellaneous manufacturers). Thoroughly remove all wood dust.

Mixing Ratio

Mix component A and B in ratio 1 : 1 (parts by volume).

Method of Application

Mixing: Cut cartridges above thread of screw  and insert both cartridges (component A + B) in a suitable dual cartridge caulking gun. Alternatively two normal caulking guns can be used. Press two threads of component A + B in same length and required quantity onto a wooden board for mixing, side by side, and close the cartridges using delivered threaded caps.  

Mix both components thoroughly with a scraper, until a homogeneously coloured and streak-free wood repair compound is achieved.
Note: Always use a board for mixing in order to prevent blistering by pressing out all air cells/bubbles with the scraper. Do not amass the filling compound on the (mixing) board but spead out. 
Accumulation of mixed product will cause a diminished pot life due to heat of reaction.  

Application: Impregnate defective areas with Capadur Repair P. Allow the primer to flash off for min. 20 minutes (but no longer than max. 2 hours), then apply wood repair compound Capadur Repair AS onto the primer. Note: The primer must not be moist. Remove all excess product with a cloth.
In a first working step apply a fine layer of Capadur Repair AS onto the wood surface by scraper, in order to achieve a proper wetting (grip/adhesion). Then fill the defect with Capadur Repair AS. Fill deeper defects wet on wet in layers of max. 5 mm. Thus a proper densification is obtained and blistering is avoided. Fill all defects with a little overspill. Excess product can be sanded the next day flush to the surface, at the earliest after 16 hrs. (at 20 °C and 60 % relative humidity).

Fill the repair compound with fitted bits of wood, when repairing large defects. Take care to provide for a min. 5 mm wide joint of repair compound on all sides between the filling bits of wood and the wood component part. Prime all contact surfaces with Capadur Repair P and, after a flash off time of 20 minutes (2 hrs. at the latest), apply Capadur Repair AS onto the full surface. Lay in all bits of wood avoiding blistering and remove all excess product with a scraper.
                                       
Capadur Repair AS is no spackling compound (putty/body filler/surfacer)!
Repair patches must be min. 5 mm deep and wide (minimum layer thickness).

Thoroughly sanded surfaces can be coated with Caparol enamels and wood stains/glazes.
Always check previously for compatibility, when products of other manufacturers are used.

Workability

Pot (working) life: Approx. 30 minutes at 20 °C air temperature. Pot life is shortened at higher temperatures. Avoid application under a glaring sun (on sun-heated surfaces).

Application Conditions

Processing temperature during application & curing: Min. 10 °C up to max. 30 °C (substrate, product and ambient air). Maximum permissible relative humidity: 85 %.

Drying/Drying Time

Drying/curing times at 20 °C and 60 % RH:
Dust dry after approx. 4 hours.
Can be sanded after approx. 16 hours.
Recoatable after approx. 16 hours with waterborne or solvent-based Caparol primers, wood paints, enamels and stains/glazes. A previous intermediate sanding is obligatory.
Chemically and mechanically stressable (fully cured) after approx. 7 days.
