TWEHA WoodProtect

Protective black wood treatment for timber façade supporting structures

TWEHA WoodProtect is a black wood preservative specially developed for timber supporting structures used in ventilated and rainscreen façade systems.

TWEHA WoodProtect provides durable protection against moisture and helps protect timber in critical areas where it may meet concrete, steel or masonry. Through its closed-cell surface structure, it helps protect the timber against wood rot while at the same time creating a suitable bonding surface for TWEHA Tape and TWEHA adhesives.
In addition to its protective function, the black color provides an important aesthetic advantage. In open-jointed façade constructions, TWEHA WoodProtect creates a dark background behind the joints, preventing the timber supporting structure from remaining visually noticeable between the façade panels.

TWEHA WoodProtect is not an adhesion primer. Its primary functions are to protect and prepare the timber supporting structure and to create a controlled surface for the subsequent TWEHA Bonding System.

Before application, the timber supporting structure must be dry, clean and free from dust and grease. The wood moisture content must be below 18%. TWEHA WoodProtect should be thoroughly mixed before use and applied in one thin, continuous and fully covering layer using a clean fine-structured roller. Multiple layers should not be applied.
TWEHA WoodProtect must not be applied to painted wood, plywood, aluminum or other metals. After application, façade bonding can normally commence after approximately 2 hours. Drying time is influenced by ambient temperature; ideal processing conditions are approximately 18–20 °C, and application below approximately 5 °C is not recommended.
After TWEHA WoodProtect has dried completely, TWEHA Tape and the appropriate TWEHA adhesive can be applied in accordance with the applicable TWEHA Instructions for Use.

Always refer to the applicable TWEHA Technical Data Sheet and Instructions for Use for the complete application

Utviklet for ytelse og effektivitet

Ingen mekanisk festing nødvendig

Dette gjør skruer og nagler overflødige, slik at panelene kan beholde et rent og sømløst arkitektonisk utseende.

Frihet i designet

Panelene kan utformes tynnere og lettere, uten at det er nødvendig å ta hensyn til mekaniske forankringssystemer.

Høy ytelse

Gir utmerket vedheft, strekkfasthet og skjærfasthet, noe som sikrer langsiktig strukturell pålitelighet.

Påføring uten grunning

Det er ikke behov for aggressive limgrunnere på de fleste underlag, noe som reduserer installasjonstiden og kostnadene.

TWEHA WoodProtect combines timber protection, surface preparation and visual finishing in one product:

01

Developed for Timber Substructures

Specifically developed for timber façade supporting structures—particularly untreated pinewood—within TWEHA Bonding Systems.

02

Black Protective Finish

Creates a dark background behind open façade joints for clean and consistent detailing.

03

Protection Against Moisture and Wood Rot

Forms a closed protective surface that withstands demanding interfaces with other construction materials.

04

Suitable Bonding Surface

Provides an appropriate substrate for both TWEHA Tape and TWEHA adhesives.

05

Easy and Controlled Application

Applied with a fine-structured roller in one thin, full-cover layer and can be applied in advance under controlled conditions.

TWEHA WoodProtect is particularly suitable for:

TWEHA WoodProtect is particularly suitable for untreated pinewood timber supporting structures and timber battens in ventilated façade constructions, as well as rainscreen façade supporting structures more broadly. It protects timber against moisture penetration, including where timber is installed in areas adjoining concrete, steel or masonry, and creates a suitable surface for TWEHA Tape and TWEHA adhesives — or a black background behind open façade joints. It is used for protecting timber supporting structures before installation in exterior bonded façade applications, as well as for preserved timber where additional treatment of the bonding surface is required.

For exterior applications, untreated pinewood must be protected all around with TWEHA WoodProtect before installation. Preserved timber only requires treatment of the surface on which the TWEHA bonding system will be applied.
