AptiScreed P is a powder admixture formulated to provide rapid drying time and improved strengths when used in traditional sand/cement screeds.
AptiScreed P is designed for use in applications where the screed is bonded to the substrate, un-bonded or floating. The standard screed mix of cement and sand mixed in the ratio of 1:3-5 is used for creating a level layer to receive the installation of the final floor finish such as tiles, wood, linoleum, vinyl etc. Traditional screeds are generally suitable for use in hospitals, schools, retail, homes etc. AptiScreed P is ideal for use in screeds covering underfloor heating systems.
The user should check the moisture of the screed before commencing to lay the floor covering to ensure compliance with the recommendations of BS 8203:2001. Typically, floor coverings can be installed between 1 to 3 weeks after casting depending on the screed thickness and drying conditions. For a 50 – 75mm cementitious screed an average drying time of seven days per 25mm should be allowed before laying the floor covering. For depths lower than 50mm the average drying time may be reduced to 3 days subject to the substrate being free from moisture. Low temperatures or excessive moisture in the underlying concrete will delay the drying of the screed. Protect the sand/cement screed from premature drying due to wind, strong sun and enforced drying conditions
AptiScreed P is supplied in 200g water soluble sachets in a box of 80 sachets. 24 months minimum shelf life when stored at normal temperature in dry conditions.
