Installation Animation of the Intrim 2 Piece Shadowline System
As a summary, when installing the SK801 we recommend you place a packer of your expected thickness flooring under the SK802 and place the SK801 on top, with a 10mm spacer between SK802 and SK801 in the groove. Fix the SK801 in place. It also ensures you can cut the two pieces to the correct length at the same time as installing the SK801. You can then leave the SK802 in position (sitting on the floor and tack or tape in place) until it is time to install the flooring, at which time you can remove the SK802, install the flooring and replace the SK802 after and fix in place. The base of the SK802 may need planing or scribing to maintain the 10mm groove prior to fixing in place.
More detailed instructions with diagrams are below:
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 two piece 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 too 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 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 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.
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 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 paper joint tape. The 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.
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.
Remove the SK802 and install the flooring and replace the SK802 after and 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 planing or scribing to maintain the 10mm groove prior to fixing in place. The skirting is now ready for painting.
