STAGE ONE - General Preparation

The correct PPE must be worn at all times during the stages below.

Do not carry out repairs in temperatures below 5°C.

Identify and remove all rotten timber using routing tools or chisels.  Once a solid and sound base has been established, clean and sand the repair zone to remove all loose fibres. Remove paint at least 10mm from the area to be treated.

Using a moisture meter, ensure the repair zone has a moisture content no greater than 18%.  If greater than 18%, apply heat using an electric heat gun, ideally set at around 60-80°C, until below 18%.

If needed prepare any timber to be used at this stage.

STAGE TWO - Stabilise the repair zone

Mix together the two components of EWS together observing the 2:1 ratio.  Once mixed thoroughly, apply immediately and liberally to the repair zone using a disposable brush.

Leave for a minimum of 20 minutes or until the product has become tacky to allow full penetration. ERC10/EHB60 must now be applied within 4 hours.

STAGE THREE - Extruding & Mixing

Insert the single unit ERC10 or EHB60 cartridge into the Timbabuild Extrusion Tool, ensuring that the label is facing up.

Extrude the first 5cm of resin and dispose of it.  Then extrude the required amount of material onto a flat perspex board.  Release pressure from the cartridge by pressing the rear tab after extrusion.

Immediately start mixing using a wide blade scraper or knife, ensuring that the product is entirely lifted from the board at least once during this process.

Once a consistant mix has been achieved, use the filler within the working time, typically around 10 minutes.  Work the filler in well to avoid air pockets when applying.

Within the gelling period tools and utensils can be cleaned using an industrial solvent-free wipe.  Please note, after this period the material can only be removed using mechanical means.

STAGE FOUR - Application

Using a blade scraper suitably sized for the repair, start to apply the filler, taking care to completely fill all open voids.

Mould the filler to the approximate shape using the knife or shuttering method.  If using timber in your repair be sure to remove any excess resin.  Always leave your repair slightly proud of the surface.

EHB60 can be easily moulded and shaped vertically and overhead due to its 'no-slump' properties.  EHB60 can also be used to depths of up to 60mm in a single layer with no restriction on length of repair.  Ideally allow EHB60 24 hours to cure before finishing, if time allows.

ERC10 is mainly used for minor repairs, splicing and sill replacements.  The product can be applied horizontally or vertically using a shuttering technique.  ERC10 can be used on repairs of up to 10mm in depth in a single application.  Typically ERC10 gels in 5 minutes and is ready to paint after 1 hour.  Please note gel and cure times are affected greatly by temperature and may need longer on occasions.

STAGE FIVE - Finishing & Painting

Look carefully at the repair and ensure it is fully cured before continuing.

If so proceed by sanding the surface flat, initially using an 80 grade abrasive paper and finishing with a 120 grade abrasive paper.  If using an electrical sander do so with caution not to overheat the surface.  When satisfied, remove all dust and fine debris with a damp cloth and allow to dry.

Any imperfections or gaps may be resolved using a standard two part filler system.

Continue by applying paint coatings as per normal timber surface.

Please ensure all steps have been carefully adhered to, particularly sanding, before starting the paint process.
