What the glaze does, where it helps and where it hurts, and how to choose for walls, wet floors and porches.
📍 We serve KL, Selangor & Putrajaya.

A glazed tile has its colour and pattern in a thin glassy top layer fired onto the body; an unglazed tile is the same material all the way through, like full-body porcelain, homogeneous tile or terracotta. Glazed tiles give the widest choice of colours and wipe clean, so they suit walls, backsplashes and indoor floors; unglazed and full-body tiles hide chips and wear and grip better, so they suit busy floors, porches and outdoors. On ClickBina's guides ceramic is RM10 – RM18, homogeneous RM15 – RM30 and porcelain RM18 – RM35 per sq ft supplied and laid (indicative 2026, Klang Valley).
A glaze is a thin glassy coating fired onto the face of a ceramic or porcelain tile. It carries the colour and pattern, seals the face and gives the finish, from matt to high gloss. An unglazed tile has no such layer: the surface you see and walk on is the tile body itself. ClickBina's tile buying guide puts the practical difference simply: a glazed tile has its colour and pattern in a thin top layer, so a chip at the edge shows a different body underneath, while a full-body or homogeneous tile has the same colour right through, so chips and wear show less.
Most tiles sold in Malaysian showrooms for walls and many for floors are glazed. The common unglazed tiles are full-body porcelain and homogeneous tiles, and natural clay such as terracotta and quarry tiles.
| Tile | Glazed? | Strengths | Watch for |
|---|---|---|---|
| Glazed ceramic | Yes | Cheapest, huge range of colours and patterns | Porous body; walls and dry floors only; chips show white |
| Glazed porcelain | Yes | Dense body, low water absorption, wide range of looks | Pattern is only in the glaze; check the wear rating |
| Full-body / homogeneous | No (or same colour through) | Chips and wear barely show; heavy traffic | Fewer patterns; polished versions are slippery |
| Terracotta / quarry | No | Warm natural clay, matt grip | Porous; must be sealed and re-sealed |
ClickBina's tiles comparison guide groups tiles by water absorption: porcelain and homogeneous below 0.5%, standard ceramic at 3–20%. That body figure matters more than the glaze for wet floors: a glazed ceramic is still a porous tile underneath.
ClickBina's tile and grout cleaning guide notes that mildly acidic descalers are safe on glazed ceramic and porcelain tiles but etch marble, terrazzo and other natural stone, another reason glazed tiles are easy to live with in bathrooms.
ClickBina's terracotta tiles guide explains that most terracotta floor tiles are unglazed, so the surface you walk on is the clay, and that they must be sealed after laying and re-sealed over time.
Glazed floor tiles carry a wear rating on the PEI scale, from I for walls only to V for heavy commercial traffic. The tile buying guide suggests PEI III for bedrooms and study rooms, PEI IV for the living room, dining room and kitchen, and PEI V for the porch, balcony and commercial entrances, and warns that a beautiful glazed tile with a low PEI rating will show wear quickly at the front door.
Unglazed full-body tiles wear differently: the surface wears, but because the colour runs through, the wear and any chips are much harder to see. If a busy floor matters more than a pattern, that is the stronger choice.
Glazed or not, slip depends on the finish. Polished surfaces look glossy but show scratches and are slippery when wet; matt surfaces hide wear and grip better; semi-polished or lappato finishes sit in between. Glossy glazed tiles are a poor choice outdoors and on wet floors. For bathrooms, wet kitchens and porches, choose a tile with a published wet-area slip rating; ClickBina's anti-slip tiles guide explains the R ratings.
| Glazed ceramic / porcelain | Unglazed porcelain / homogeneous | Unglazed terracotta / quarry | |
|---|---|---|---|
| Sealing | Not needed on the face | Usually not needed | Seal after laying, re-seal over time |
| Stains | Wipe off the glaze | Polished faces may need care | Absorbs oil and stains if unsealed |
| Acidic descaler | Usually safe; test first | Usually safe; test first | Check the sealer maker's advice |
| Chips | Show the body colour | Barely show | Show, but suit a rustic look |
Grout is porous on every tile type, so the joints still need cleaning and, in wet areas, a stain-resistant grout.
A glaze is smooth and dense, which makes adhesion the main risk when you cover old tiles. ClickBina's tiling over tiles guide notes that plain sand-cement does not grip a glazed surface, and that the glazed face must be degreased and roughened or primed as the adhesive maker specifies. The same applies to paint and epoxy: the painting over tiles guide says high-gloss glazed tiles need more abrasion and a dedicated bonding primer.

💬 WhatsApp for a quoteTerracotta and other natural clay tiles vary too much by product to give one price; the terracotta guide quotes them once the tile is chosen. Whatever the tile, hacking, levelling, skirting and sealing are priced on top of the supply-and-lay rate.
We do tiling as part of renovation work: hacking, levelling and laying glazed, full-body and natural clay tiles, and matching the tile to each room. WhatsApp us your job details for a quote: your area, the rooms and rough size in sq ft, and the existing floor.
