For Lyme Regis jobs where gypsum-based screed is ruled out, wet rooms, balconies, timber-sensitive junctions, we lay a semi-dry sand and cement mix, bay by bay, finished to SR2 with a hand float or power trowel.
For Lyme Regis 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.
Most of our Lyme Regis jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Lyme Regis sits Exeter (28 mi), and we work the surrounding villages on the same week's diary.
Who this is for in Lyme Regis
Lyme Regis is a coastal town, so damp control, salt exposure and tight winter pour windows shape every brief. We work the diary around that — and around the holiday-let turnover that funds half the jobs here.

Traditional Sand & Cement Screed in Lyme Regis — how it works
Unlike a self-levelling liquid screed, sand and cement is placed and compacted by hand, so we control the fall towards a drain, form an upstand at a threshold, or feather it into an existing floor level in a way a pumped pour cannot.
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.
What to expect on pour day in Lyme Regis
- 1
Site visit to assess substrate, falls, depth and access, since sand and cement can be barrowed where a pump truck cannot reach
- 2
Substrate prep, priming or DPM, and setting out of bay lines and laser levels
- 3
Mix and place the screed in bays, compacting as we go to remove voids
- 4
Hand float or power trowel to a flat, dense SR2 finish
- 5
Protect and allow to cure, typically a day per millimetre of depth after the first 50mm
- 6
Follow-up inspection before floor coverings or tiling begin

FAQs from Lyme Regis clients
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 Lyme Regis job.
How is sand and cement screed different from liquid screed in Lyme Regis?+
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.
How long does a sand and cement screed take to dry in Lyme Regis?+
Roughly a day per millimetre of depth once past the first 50mm, so a 65mm floor is typically ready for coverings in around six to eight weeks, depending on ventilation and site conditions.
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.
Do you use a screed pump for sand and cement in Lyme Regis?+
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.
