Seaton builders sometimes need a screed that can be laid in a bucket-and-barrow operation with no pump access, or that has to tie into an external step, drain or wet room upstand. That is exactly where sand and cement wins over a liquid pour.

Sand and cement screed is laid in bays with day joints, which we set out to avoid future cracking at natural stress points such as doorways and changes in depth. It is a more labour-intensive process than liquid screed, but it is proven, robust and unaffected by moisture the way calcium sulphate screeds can be.

Most of our Seaton jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Seaton sits Exeter (24 mi), and we work the surrounding villages on the same week's diary.

Traditional Sand & Cement Screed in Seaton — how it works

For Seaton wet rooms, balconies and any area with sustained water contact, sand and cement is usually the only sensible screed choice, since gypsum-based liquid screeds are not designed to tolerate standing water.

We mix a semi-dry sand and cement screed on site or bring it in via a screed pump, lay it to string lines or laser-set pins in bays, then compact and trowel it to a flat, dense surface. It is slower than a liquid pour, roughly a day of drying time per millimetre of depth once you get past the first 50mm, but it tolerates a much wider range of site conditions.

Common Seaton build questions

Can you form a fall to a drain with sand and cement?+

Yes, this is one of the main reasons to choose it. We build the fall into the screed thickness during placement, which liquid screed cannot do since it self-levels flat.

How is sand and cement screed different from liquid screed in Seaton?+

Sand and cement is a semi-dry mix, hand-laid and trowelled in bays, whereas liquid screed is pumped and self-levels. Sand and cement suits deep fills, external areas and wet rooms; liquid screed suits large flat internal floors that need to dry quickly.

What SR rating do you achieve on a trowelled screed?+

We finish sand and cement to SR2, within 3mm under a 2m straight edge, which is suitable for most tiled finishes. If you need SR1 flatness for large-format tile or resin, liquid screed is usually the better route.

Will the screed crack?+

Bay joints and fibre reinforcement control shrinkage cracking. We set bay sizes and joint positions at doorways and depth changes to minimise the risk on any Seaton job.

Do you use a screed pump for sand and cement in Seaton?+

On larger jobs, yes, a screed pump can deliver the semi-dry mix into the building, which speeds up placement while keeping the hand-trowelled finish.

Can you match an existing sand and cement floor level?+

Yes, we set datums off your existing finished floor level and build the new screed to match, allowing for whatever covering goes on top.

Sand and cement screed still has a firm place in Seaton building work, wet rooms, external thresholds and deep fills all reward a hand-laid, trowelled finish over a fast liquid pour.
