How to Install the Intrim 2 Piece Shadowline System

We have prepared easy to follow steps together with detailed illustrations to assist you install the Intrim SK801,  Intrim SK802, Imtrim SK803 and Intrim SK804 Series Shadowline Skirting 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:

STEP ONE:

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)

STEP TWO:

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.

STEP THREE:

Install SK801 upper ribbed portion of skirting

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 into every stud at a maximum distance of 600mm centres.

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.

STEP FOUR:

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.

STEP FIVE:

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)

STEP SIX:

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

STEP SEVEN:

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.

STEP EIGHT:

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.

STEP NINE:

Remove the SK802 and install the flooring and replace the SK802 after and fix in place at every stud. 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.
