What goes wrong — and the correct fix

A working library of the failures we actually see on Sarawak jobs, each shown three ways: what you see, why it happens, and the correct recovery. It’s not a scare list — it’s how you tell a real fix from a cover-up, and how the right specification designs the problem out before it starts.

Board swelling

What you see您看到的现象Apa yang anda lihatA door or carcass panel has puffed up along an edge or base — the surface lifts and the board feels soft.
Why成因MengapaWater reached the board core, usually through an unsealed cut edge, a failed joint, or standing water under a sink. Once the core wicks moisture it swells and won't recover.
Correct fix正确的修复方式Pembaikan yang betulReplace the affected panel, trace and stop the water path, and re-seal or upgrade the exposed edges. Where the zone stays wet, move that carcass to a non-wood material.
Design it out从设计上避免Elakkan dari peringkat reka bentukMatch the material to the moisture zone from the start — a non-wood (aluminium/ACP) carcass in the wet zone removes the board-swelling risk at the source. Joints, edges and seals still need correct specification.

Poor silicone seal

What you see您看到的现象Apa yang anda lihatThe silicone line at a worktop, splashback or sink is cracked, peeling or mouldy — water can track behind it.
Why成因MengapaWrong sealant grade, a damp or dusty surface at application, or an over-wide gap — the bead loses adhesion and splits.
Correct fix正确的修复方式Pembaikan yang betulCut the failed bead out completely, clean and dry the joint, then re-apply the correct neutral-cure sanitary-grade silicone in one continuous, properly-tooled line.
Design it out从设计上避免Elakkan dari peringkat reka bentukSpecify the right sealant for the joint and confirm the gap width before install. A joint sized and prepped correctly is what keeps water out — not the panel alone.

Aluminium scratch

What you see您看到的现象Apa yang anda lihatA visible scratch or scuff on an aluminium frame, front or profile — often from moving appliances or site traffic.
Why成因MengapaAbrasion through the powder-coat or anodised surface during handling, cleaning with the wrong pad, or dragged cookware and appliances.
Correct fix正确的修复方式Pembaikan yang betulLight marks polish out; deeper scratches are touched in with a colour-matched coating pen, or the visible profile is refinished or replaced so the repair disappears.
Design it out从设计上避免Elakkan dari peringkat reka bentukProtect finished surfaces through the rest of the build, and clean with a soft cloth — never an abrasive pad — so the coating stays intact.

Uneven or leaning wall

What you see您看到的现象Apa yang anda lihatA gap opens between the cabinet and a wall that leans or bows, or the worktop reads out of level along the run.
Why成因MengapaThe wall itself is out of plumb — common in older or fast-built homes. Cabinets are straight, so the wall's lean shows up as a tapering gap.
Correct fix正确的修复方式Pembaikan yang betulClose it with a scribed filler panel cut to the wall line, so the run reads straight and the gap disappears instead of being caulked over.
Design it out从设计上避免Elakkan dari peringkat reka bentukMeasure wall plumb at the site-measurement stage and design in scribe and filler allowances before production, so nothing is left to on-site guesswork.

Window water ingress

What you see您看到的现象Apa yang anda lihatWater appears on the sill or inside the frame after heavy rain — pooling, staining or a damp reveal.
Why成因MengapaBlocked or missing drainage (weep) holes, a failed perimeter seal, or the frame set without the right fall, so wind-driven water can't escape and backs up.
Correct fix正确的修复方式Pembaikan yang betulClear or add the drainage path, renew the perimeter seal, and correct the sill fall so water drains out the way the system is designed to.
Design it out从设计上避免Elakkan dari peringkat reka bentukA correctly drained and sealed aluminium window handles Sarawak's driving rain — but the drainage detail, the seals and the installation all have to be right, not just the frame.

Lifting or chipped edge

What you see您看到的现象Apa yang anda lihatThe edge banding on a door or panel is peeling, chipped or lifting at a corner — dirt and moisture can now reach the core.
Why成因MengapaWeak edge adhesive, heat or steam at the edge, or an impact. Once the band lifts, the exposed core is vulnerable.
Correct fix正确的修复方式Pembaikan yang betulRe-band or replace the affected edge with a moisture-resistant band (such as a PUR-bonded edge), sealing the core again.

Termite attack

What you see您看到的现象Apa yang anda lihatTimber or board components show tunnelling, hollowing or frass — termites have got into the carcass or substructure.
Why成因MengapaSarawak's subterranean termites feed on cellulose, so any untreated timber or board in a risk zone is food.
Correct fix正确的修复方式Pembaikan yang betulRemove and replace the affected components, treat the area, and substitute a non-wood material where the risk is highest — termites can't feed on aluminium or ACP.
Design it out从设计上避免Elakkan dari peringkat reka bentukNon-wood construction removes the termite-food risk from the carcass itself. Where timber stays, insist on treated substructure and keep it out of direct ground and wet contact.

Design judgement stays judgement, not a standard: where a figure or material choice is ALUMAX or design guidance for Sarawak conditions, it is a recommendation and not a code requirement. Regulatory requirements — plan approval, natural ventilation and sanitary provisions, fire, water supply and plumbing connection — must be confirmed with your local authority (PBT) for your specific project. Product performance figures (coating life, corrosion, water resistance, hardware cycle life, emission class) follow the named manufacturer's own specification and certification. Structural, M&E and fire works must be carried out or endorsed by the appropriate registered professional. Where a guide names a measurement concept such as ΔE colour difference, it is a method, not a fixed pass/fail number — the acceptance limit is agreed in writing per project.设计判断始终只是判断，而非标准：凡是针对砂拉越条件的数字或材料选择属于 ALUMAX 或设计建议的，都是建议，而非法规要求。法规要求——图则批准、自然通风与卫生设施、消防、供水与管道接驳——必须就您的具体项目向您当地的地方政府（PBT）确认。产品性能数字（涂层寿命、腐蚀、耐水性、五金循环寿命、释放等级）依据所列制造商本身的规格与认证。结构、机电（M&E）与消防工程必须由相应的注册专业人士执行或背书。凡指南提及诸如 ΔE 色差之类的测量概念，它是一种方法，而非固定的合格／不合格数字——验收限值须逐项目以书面议定。Pertimbangan reka bentuk kekal sebagai pertimbangan, bukan satu piawaian: apabila sesuatu angka atau pilihan bahan adalah panduan ALUMAX atau panduan reka bentuk untuk keadaan Sarawak, ia adalah cadangan dan bukan keperluan kod. Keperluan kawal selia — kelulusan pelan, peruntukan pengudaraan semula jadi dan sanitari, kebakaran, bekalan air dan sambungan paip — mesti disahkan dengan pihak berkuasa tempatan (PBT) anda bagi projek khusus anda. Angka prestasi produk (jangka hayat salutan, kakisan, rintangan air, jangka hayat kitaran perkakasan, kelas pelepasan) mengikut spesifikasi dan pensijilan pengeluar yang dinamakan itu sendiri. Kerja struktur, M&E dan kebakaran mesti dilaksanakan atau disahkan oleh profesional berdaftar yang berkenaan. Apabila sesuatu panduan menamakan konsep pengukuran seperti perbezaan warna ΔE, ia adalah satu kaedah, bukan nombor lulus/gagal yang tetap — had penerimaan dipersetujui secara bertulis bagi setiap projek.

Avoid the failure in the first place

The fix you never need is the right material, in the right zone.

Most of these start as a specification decision, not a repair. Match the material to your moisture zone first — then price and buy on alumax.pro.
