Frequently Asked Questions
What is a cement additive?
A cement additive changes the properties of screeds, renders, mortars, and grouts. Products in this range improve bond strength, water resistance, or efflorescence control. Mix the additive into the batch water before adding cement.
How do I stop efflorescence in tiled surfaces?
Add Efflock or EP Efflorescence Remover to mixing water at a 1:100 ratio. Both repel liquid water while staying vapour permeable. Use GP cement only. One litre covers 16 square metres of screed, adhesive, and grout combined.
What is the difference between PVA, acrylic, and SBR latex additives?
PVA suits general bonding and plasticising at low cost. Acrylic offers higher bond strength. SBR latex from Gripset 11Y and Mapei Planicrete SP provides the best water resistance and flexural strength for wet-area screeds.
Which cement additive is best for wet-area screeds?
Gripset 11Y and Mapei Planicrete SP are SBR latex admixtures for wet-area screeds. Gripset 11Y doubles as a primer at one litre per 3 square metres. Planicrete SP reaches 25 MPa compressive strength in screeds. Both resist water well.
Can I use a cement additive with latex-modified grout?
Yes, but Efflock and EP delay their water-repellent effect by about six days when used with latex products. Bond strength is not affected. Allow extra drying time before exposing the surface to rain or running water.
