Rectified tiles are ceramic or porcelain tiles that have been precisely ground and machined to give them near-perfect straight edges and exact dimensions. These tiles provide a very clean, symmetrical look, and allow for extremely fine grout lines of 3mm or less (typically using un sanded grout, which is most appropriate for thin grout lines).Rectified tiles usually also have a very fine bevel around their top edge too, to help reduce the chance of their sharp edges chipping.These tiles are also known as ‘dimensionally stable tiles’ (which is a bigger mouthful and no more descriptive) – and are often referred to as ‘sharp edge’ tiles because they’re quite sharp at the edge.Because of this sharpness and the likelihood that they’ll be chipped, a bit of thought needs to go into how they’re used for outward facing edges. Where necessary, bull nose tiles can be used to give softer edges. Conventional non-rectified tiles are called cushion-edged, soft-edged or pillow-edged, and aren’t as sharp or prone to chipping on their edges.For practical reasons, it’s unusual to find rectified tiles smaller than about 300mm x 300mm.Rectified tiles are practically identical in terms of length and width – the machines used to cut them work to very fine tolerances, and for most people’s purposes there won’t be a noticeable difference from one tile to the next.Having said that, the tile’s thickness isn’t normally taken into account during rectification – only the length and width – so there may be slight variations in terms of thickness. Likewise, ceramic tiles may also be subject to a tiny bit of warping.Because rectified tiles are usually laid very close together with only a sliver of grout separating them, these small differences may occasionally mean that tiles aren’t (or don’t seem to be) perfectly flush with each other.This slight difference where tiles aren’t exactly even with one another is called ‘lippage’. With thicker grout lines like you’d use with unrectified / soft-edged tiles, this amount of lippage would be barely noticeable, and could be easily masked with a gradual slant.
