Cut DJ800 door jamb material to required lengths with a 45-degree mitre cut to the top of stiles and each end of the head.

Assemble the head and stile mitre joints with PVA glue and nails or screws. (Detail A)

Pack opening and install DJ800 door jamb plumb and level. Take care when installing jamb material, to make sure it is fixed parallel with timber framework. (example – if framework is 90mm wide and plasterboard is 10mm thick = 90mm frame + (2 x 10mm) 2 thicknesses of plasterboard + (2 x 3.5mm) 2 thicknesses of plaster set = 117mm total width of DJ800 door jamb, therefore the difference between timber framework face and door jamb face = (117 – 90) divided by 2 = 13.5mm on both sides between the jamb face and framework face. (Detail B)

Once all DJ800 door jambs are installed, it is time to install the SK800 skirting.

Cut SK800 skirting to required lengths to fit neatly between door jambs and internal and external corners of framework. Cut SK800 skirting with 45-degree mitre cuts for internal and external corners.

SK800 Skirting must be nail or screw fixed to timber frame, and screw fixed only to steel frame, into every stud at a maximum distance of 600mm centres. (minimum of 2 fixings per stud up to 90mm wide,
minimum of 3 fixings per stud for 135 to 185mm wide, and minimum of 4 fixings per stud for 235 to 285mm wide). These fixing points must include 1 fixing 20mm from base of skirting board and another
fixing must be through the centre of ribbed section at top of skirting board.
Install with 5mm packers between the bottom edge of skirting and floor to allow for any subframe movement.(Detail B)
(Refer to Figure 2)

Install plasterboard sheet to framework as per manufacturer’s specifications. Cut and fit plasterboard sheet as close as possible to door jamb and skirting edges. It is preferable to have the factory finish plasterboard edge sitting on the top of SK801 skirting edge.

Install all PVC stop beads (PLTB 630 – 30mm x 6mm tear off bead) to door jamb surrounds and metal perforated angles to external wall corners, taking care to cut the corners to a point to eliminate plasterset material build-up. (Detail C)

Brush down the top ribbed section of the skirting to remove all dust prior to plaster setting. Set all plaster joints including the joint where the bottom edge of wall plasterboard sits on top of the shadowline skirting (SK801), using FibaFuse or paper joint tape. (Any tape used that does not meet the recommended tape types will void all warranty). The FibaFuse or paper joint tape should be centrally positioned within the joint so the bottom edge of the tape comes within 15 – 20mm of the bottom edge of the ribbed section of skirting.

All plaster set and accessories must be installed to manufacturer’s specifications and instructions.

TIP: To avoid the join between the skirting & plasterboard from cracking, you must allow the jointing compound to dry fully between coats as per the manufacturer’s specifications and instructions. Drying times are approximately 24 hours in normal conditions or 48 hours in cool conditions between each coat. See USG Boral instructions here

Apply plaster set to PVC stop beads around door jamb surrounds. All plaster set and accessories must be installed to manufacturer’s specifications and instructions.

Apply all coats of plaster set including top coats to all plaster joints and sand. Tear of PVC lip on stop bead around door jamb surrounds and it is now ready for painting. All plaster set and accessories must be installed to manufacturer’s specifications and instructions.

Cut DJ800 door jamb material to required lengths with a 45-degree mitre cut to the top of stiles and each end of the head. Assemble the head and stile mitre joints with PVA glue and nails or screws.

Pack opening and install DJ800 door jamb plumb and level. Take care when installing jamb material to make sure it is fixed parallel with timber framework. (Example – if framework is 90mm wide and plasterboard is 10mm thick = 90mm frame + (2x10mm) 2 thicknesses of plasterboard + (2×3.5mm) 2 thicknesses of plaster set = 117mm total width of DJ800 door jamb, therefore the difference between timber framework face and door jamb face = (117-90) divided by 2 = 13.5mm on both sides between the jamb face and framework face.
Once all DJ800 door jambs are installed it is time to install the two pieces SK801 and SK802 skirting.

Install SK801 upper skirting section. Keep the two pieces of skirting together and cut SK801 (top portion-fixed) and SK802 (lower portion of skirting – not fixed) to required lengths to fit neatly between door jambs and internal and external corners of framework. Cut SK801 and SK802 skirting with 45-degree mitre cuts for external corners and scribe joints for internal corners.
After cutting 2 pieces to length, keep the upper and lower portion together while installing.
When installing the 2-piece skirting place a packer with the expected finished thickness of flooring plus a 3 mm expansion gap, on top of existing flooring and underneath the SK802 and place the SK801 on top, with a 10mm spacer in the groove between SK802 and SK801 to keep the groove consistent and fix the SK801 only in place.
SK801 skirting must be nail or screw fixed to timber frame and screw fixed only to steel frame, into every stud at a maximum distance of 600mm centres. Must be fixed with 1 screw or 2 nail fixings through the ribbed section.
As you remove the floor thickness plus 3mm packers from the underside of the SK802 it will now lower onto the existing floor material leaving a large gap between the SK801 and SK802.
Temporarily tack or tape SK802 in place, until it is time to install the flooring.
Note: Do not permanently fix the lower SK802 portion in place at this stage.

Install plasterboard sheet to framework as per manufacturer’s specifications. Cut and fit plasterboard sheet as close as possible to door jamb and skirting edges. It is preferable to have the factory finish plasterboard edge sitting on the top of SK801 skirting edge.

Install all PVC stop beads (PLTB 630 – 30mm x 6mm tear off bead) to door jamb surrounds and metal perforated angles to external wall corners, taking care to cut the corners to a point to eliminate plaster set material buildup.

Brush down the top ribbed section of the skirting to remove all dust prior to plaster setting. Set all plaster joints including the joint where the bottom edge of wall plasterboard sits on top of the shadowline skirting (SK801), using FibaFUse or paper joint tape. (Any tape used that does not meet the recommended tape types will void all warranty). The FibaFuse or paper joint tape should be centrally positioned within the joint, so the bottom edge of the tape comes within 15-20mm of the bottom edge of the ribbed section of skirting.
All plaster set and accessories must be installed to manufacturers specifications and instructions.
TIP: To avoid the join between the skirting and plasterboard from cracking, you must allow the jointing compound to dry fully between coats as per the manufacturer’s specifications and instructions. Drying times are approximately 24 hours in normal conditions or 48 hours in cool conditions between each coat. See USG Boral instructions here.

Apply all coats of plaster set including top coats to all plaster joints and sand. Tear off PVC lip on stop bead around door jamb surrounds and it is now ready for painting. All plaster set and accessories must be installed to manufacturers specifications and instructions.

Remove the SK802 and install the flooring and replace the SK802 with a 3mm expansion gap between bottom edge of SK802 and flooring. Fix in place at every stud (minimum of 2 fixings per stud up to 90mm to 135mm wide, minimum of 3 fixings per stud for 185mm to 235mm wide and minimum of 4 fixings per stud for 285mm wide). The base of the SK802 may need planning or scribing to maintain the 10mm groove and 3mm expansion gap prior to fixing in place. The expansion gap to be filled prior to painting with flexible paintable gap filler typically applied using a caulking gun. The skirting is now ready for painting.

Cut SK800 to required lengths to fit neatly between door jambs and internal and external corners of framework. Cut SK800 skirting with 45-degree mitre cuts for internal and external corners.
FR MDF SK800 must be screw fixed to steel frame into every stud at a maximum distance of 600mm centres. (Minimum of 2 fixings per stud up to 90mm wide, minimum of 3 fixings per stud for 135 to 185mm wide and minimum of 4 fixings per stud for 235 to 285mm wide). These fixing points must include 1 fixing 20mm from base of skirting board and another fixing must be through the centre of ribbed section at top of skirting board. Install with 5mm packers between the bottom edge of skirting and floor to allow for any subframe movement. Apply a bead of Bindex Fire & Acoustic Sealant between base of skirting and floor substrate.

Using 50mm CSR Fibretex 350 Rockwool. Cut and fix in between framing studs and rear faces of skirting boards allowing a maximum distance between the face of the insulation and the rear face of skirting of 14mm.
The height of the insulation must be 160mm minimum above top edge of skirting.

Using 16mm Fire Grade Plasterboard, Install plasterboard sheet to framework as per manufacturers specifications. Cut and fit plasterboard sheet as close as possible to door jamb and skirting edges. Preferable to have the factory finish plasterboard edge sitting on the top of SK800 skirting edge.

Brush down the top ribbed section of the skirting to remove all dust prior to plaster setting. Set all plaster joints including the joint where the bottom edge of wall plasterboard sits on top of the Shadowline skirting, using paper joint tape or FibaFuse tape. (Any tape used that does not meet the recommended tape types will void all warranty).
The tape should be positioned within the joint, so the bottom edge of the tape comes within 5-10mm of the bottom edge of the ribbed section of skirting. All plaster set and accessories must be installed to manufactures specifications and instructions.

Apply all coats of plaster set including top coats to all plaster joints and sand. All plaster set and accessories must be installed to manufacturers specifications and instructions.
TIP: to avoid the join between the skirting and plasterboard from cracking you must allow the jointing compound the dry fully between coats as per the manufacturer’s specifications and instructions.
