Grades and products for Clipstone Park specifications
A calcium sulphate screed grade is written as a short code. C stands before the crushing figure (compressive strength) and F before the bending figure (flexural strength), with both given in N/mm2.
CA-C20-F4 is the light-duty grade for domestic floors. A typical house, apartment or office is specified at CA-C25-F5, and floors facing heavier wear get CA-C30-F6. On a Clipstone Park drawing the designer sets the grade, and we pour exactly that grade; where no grade is given, we recommend one to suit the use.
An alpha hemihydrate product comes in when the build needs quicker drying or a slimmer section. Each follows its own product sheet for depth and drying, so the general rules for calcium sulphate do not always apply.
Because the material hardly shrinks, an open-plan ground floor, or the long corridors and open floors of an apartment building, can go down in big bays with few breaks. Doorways and the lines between heating zones still get a planned joint layout before any screed arrives.
Apartment floors are the other main use in the town. 15% of homes in Leighton Buzzard are in purpose-built blocks of flats, and calcium sulphate screed is a common choice on upper floors because it pumps to height and settles flat. The guide to anhydrite screed explains how the material behaves as it sets and dries.
Finishing anhydrite floors in Leighton Buzzard homes
A calcium sulphate floor needs a set routine before any covering goes on.
Laitance comes first. Setting leaves a thin, weak skin on top, and once the floor is dry it has to be sanded away; left in place, it is what the adhesive and primer grip instead of the screed itself.
Then the moisture test. A lot of flooring brands tolerate a drier reading on calcium sulphate than on cement, so judge the hygrometer result against the calcium sulphate figure, never the cement one. A hygrometer test gives it. Got pipes under a Clipstone Park floor? Running the system from about 7 days usually speeds drying, and our underfloor heating screed page covers that warm-up.
Next it is primed, using a primer made for calcium sulphate, which is essential before cement based tile adhesive or levelling compound goes on.
Keep this screed away from anything that may get wet: a wet room, a shower area or any floor where water could sit needs a cement based flowing screed instead.
