- Q1. What is the minimum depth for unbonded screed?
Answer - Unbonded screed should not be less than 50mm for traditional screed, but modified screeds can go to as little as 40mm. - Q2. What is the minimum depth for bonded screed?
Answer - Bonded screeds can go to a 15 mm in thickness , as long as it is bonded chemically (epoxy) or laid with SBR/PVA bond and SBR/PVA modified screed mix. If the screed is to be cement bonded then 25mm should be the minimum depth. - Q3. What are structural screeds?
Answer - Structural screeds are very hard wearing and capable of withstanding heavy point loads, these tend to be used in certain environments such as industrial units and floors which will take excessive foot traffic and certain types of plant. CSC have a particular wealth of technical knowledge and experience in this sector, talk to our Technical Support team on 0845 500 4055. - Q4. What type of floor screeding should I have in my new house/extension?
Answer - Both Free-Flowing and Sand & Cement screeds are the recommended for domestic use. Modified screeds such as FlexiDry offer stable, fast drying solutions. - Q5. What are the advantages of flowing screeds over traditional forms of floor screeding?
Answer - Flowing screeds are good for laying a large area over a short amount of time, screed installation is faster but requires much more time for preparation as a tanked system is required. - Q6. What reinforcment is the best option for an unbonded floor screed?
Answer - Screed reinforcement is a recommendation for use in screed constructions. There are various options that can be adopted which consist of fibres or metal mesh. The general purpose is to restrain the drying stress generated from the cement in a screed system. The natural process is for the screed to try to curl and crack as well as shrinkage that is inherent in cementitious products. The reinforcement is designed that if a crack occurs, it will hit the mesh / fibres and deflect the stress, therefore reducing the effect. If there are any specific reinforcement requirements over and above this, then we would address this as a specific subject to detailed information being supplied. - Q7. What is the tolerence for levels on floor screeds?
Answer. It is important to understand and separate tolerance as Departure from datum and Surface regularity. Departure from datum can be 15mm for large areas and 10mm for smaller areas. Surface regularity is SR1 = 3mm under two meter straight edge on legs, SR2 = 5mm and SR3 = 10mm. CSC offer screeds to SR2 and SR1 is achieved by applying a latex compound which gives a fine surface finish to receive thin flooring finishes such as vinyl. - Q8. Why should I use CSC Screeding Limited for my floor screeding works?
Answer – As professionals in the screed business, CSC Screeding are capable of managing complex technical demands, challenging project performance targets and tight budgets. - Q9. My underfloor heating system installer has told me that self-levelling ‘flowing’ screed is the best for UFH, why is this?
Answer - Under-Floor Heating installers have a limited knowledge of screed systems and recommend you discuss your requirements directly with CSC to obtain a more informed insight on performance. - Q10. What is the curing and drying time for floor screeds?
Answer - This varies depending on the type of screed, the depth of the screed, the environment in which it is being installed and if accelerated drying additives are being used as part of the screed system. Call our Technical Support on 0845 500 4055 to discuss this important aspect in more detail. Do not attempt to lay the floor finish until you know exactly when the screed will be in a state. - Q11. I’ve heard about shrinkage cracking & curling in floor screeds, what are these and how do they occur?
Answer - Cracking and curling can be caused by a number of reasons and are inherent in cementitious systems. A cracked floor is not necessarily a failed floor and remedies are recognized in the BS8204 Part 1 2003. Consideration needs to be given as to the final floor covering to determine which level of repair is required. Please do not be alarmed if a crack appears in your screed, just pick up the phone and speak to the professionals for advice or view our knowledge centre for more detail.
