Common questions
The questions asked most often before an order — the material itself, cutting and mitring, which adhesive, how it is sold, and getting 3 m lengths to site. If yours is not here, ask before you order.
15 questions
What PS actually is
Can it go in a bathroom, a kitchen or on a damp wall?
Yes — bathrooms, kitchens, laundries and the damp side of a wall are all ordinary jobs for it, fitted exactly as it would be anywhere else. For a spot in direct sun and rain, tell us where it is going before you order so we can match the section and the fixing to it.
Does it need painting, and can I paint over it?
No — and painting over it is a poor trade. Wipe it with a damp cloth: there is no sanding and no re-varnishing every few years the way timber wants. If you need a colour outside these 11, ask us before you order rather than buying it and painting it yourself, because the wood-grain surface is applied at the factory and a coat you put on afterwards is a different thing altogether.
How does PS differ from timber and WPC?
PS is far lighter than timber, termites will not eat it, it does not swell when wet, and it needs no painting because the wood-grain finish is applied at the factory. Against WPC it is tougher and less brittle. Where timber still wins: curved runs, and the feel of real wood.

What do I cut it with, and how do I get a tight mitre?
A fine-tooth handsaw or a mitre saw; both leave a clean edge without chipping. Most room corners are not exactly 90°, so if two 45° cuts still show a gap, measure the real angle of that pair of walls and halve it. Cut 2–3 mm long and creep up on the fit — easier than cutting short and having to join. On an external corner, let the longer piece set the line and bring the short one to it. If you would rather not cut at all, send us the lengths you measured and we will cut before dispatch.
See cutting and mitresWhich adhesive, and how should the wall be prepared?
Construction adhesive or decorator's silicone, run as a bead along the length. Press it to the wall and hold it with masking tape or a prop until it sets. The wall must be dry and dusted off first; masonry, plasterboard and timber walls are all fine. On an uneven wall add more points of adhesive rather than forcing one spot. The single caution: polystyrene is sensitive to some solvents, so if you are using a brand you have not used on PS before, test it on an offcut and let it dry before you commit to the run.
Read the full fitting guideDo you fit it for me?
Yes, in Bangkok and the five surrounding provinces — Nonthaburi, Pathum Thani, Samut Prakan, Samut Sakhon and Nakhon Pathom. Quoted per job, because it depends on the run length, how many corners there are, and what floor it has to be carried to. Send the measurements and a photo of the room on LINE and we will price it. Outside that area we do not fit, but the install guide here covers all eight steps, including the corners and the table for walls that are not square.
Read the install guideIf I take it off later, will the wall be damaged?
Honestly, we cannot promise anything about your wall. Construction adhesive holds harder than silicone, and pulling it off can bring paint with it. How much depends on the paint that room was finished in and the state of the wall underneath — neither of which we can see or predict. If you rent, ask the owner or the building before fitting. The other option is decorator’s silicone instead of construction adhesive: easier to remove and it marks less, in exchange for holding less well, which suits a light profile on a flat wall.
How it is sold, how much to order, and delivery
Is it sold by the length or by the metre — and how is a door sub-frame counted?
Skirting, cornice, wall panels and battens are sold by the length: one length is 3 m, and you order lengths. A ซับวงกบ door sub-frame is sold as a set for one door leaf, because a leaf needs both jambs and the head — so one set is three 3 m lengths. Keep the two units apart when you price a site, or the sub-frames come out two thirds short.
| Product | Sold as | 3 m sticks used |
|---|---|---|
| Skirting · cornice · wall panel · batten | per 3 m length | 1 length |
| Door sub-frame (ซับวงกบ) | per set, one door leaf | 3 lengths |
How do I work out how many lengths to order?
Measure the total run in metres, subtract the door openings, divide by 3 and round up — that is your number of lengths. Then allow roughly one more length per room for mitre offcuts, and more in a room with many corners. Worked example: a 4 × 5 m room is 18 m round, less 1 m of doorway leaves 17 m; 17 ÷ 3 = 5.67, round up to 6, allow for the mitres and order 7. If you would rather not do the arithmetic, send the measurements or a photo of the plan and we will work it out.
Do you cut to my measurements?
No — we cut to standard lengths only, chosen at checkout: a full 3 m stick, 2M+1M, 1.5M+1.5M, or 1M+1M+1M. The split lengths are easier to carry and fit in a lift. Cutting to the exact run and mitring the corners is the installer's work on site.
Can cut-to-size orders be returned?
No — a piece cut to your measurements cannot be resold. Please check the size, colour code, lengths and quantities before ordering, and ask first if you are unsure.
How do I pay?
You pay when you order, by credit card, debit card or PromptPay. The payment page belongs to Stripe, the payment processor, and card numbers never reach our servers. If you pay by credit or debit card and the order does not arrive as agreed, you can dispute the charge with your card issuer yourself, without going through us. PromptPay is a transfer and carries no such right.
How do 3 m lengths get delivered, and what does delivery cost?
Nationwide, with every length wrapped against knocks before it goes on the truck. Delivery is free nationwide during the promotion, on every order, with no minimum — the total you see in the cart is the total you pay. Unwrap and look before you sign for it: photograph anything damaged in transit and tell us within 24 hours and we replace it. If a long vehicle cannot reach the address, or it has to go up a tall building, say so when you order — or have us cut the lengths shorter so they are easier to carry.
If I order more later, will the colour match the first batch?
Order with the same three-digit colour code and the colour is referenced to the same set across the whole catalogue, so a phased job or a later extension stays in the same tone. And because every range shares that set, the skirting, the cornice and the slat panel in one room really can be ordered in one colour. Keep the code with your order, or photograph the box: repeat orders get much quicker.

What door frame sizes are there, and can any size be ordered?
Six: 70×180, 70×200, 80×180, 80×200, 90×180 and 90×200 cm, ฿1,590–1,990 a set, each set being two posts and a head. Every size can be ordered at any time, because a frame is cut to the order rather than taken off a shelf — so nothing is ever out of stock. The colours are the same eleven the skirting and sub-frames use.

Tell us where it is going, the lengths you measured, and how many doors or rooms. That is enough for us to come back with the right sections, the number of lengths and the delivery cost.
