Yes, you can use a mixture of acrylic polymer and cement for roof slab grouting as a waterproofing treatment. This combination offers several benefits:-
1. Improved flexibility:-
Acrylic polymer adds flexibility to the grout, reducing the likelihood of cracks and improving durability.
2. Enhanced adhesion:-
The polymer enhances the bond between the grout and the concrete, ensuring a strong and lasting attachment.
3. Water resistance:-
Acrylic polymer improves the water resistance of the grout, reducing the risk of water infiltration and damage.
4. Workability:-
The addition of polymer can improve the grout’s workability, making it easier to mix and apply.
However, consider the following:-
1. Ratio:-
Typically, a 1:1 to 1:3 (polymer:cement) ratio is used.
2. Compatibility:-
Ensure the acrylic polymer is compatible with the cement and other materials used in the grout.
3. Curing:-
Allow the grout to cure according to the manufacturer’s instructions, usually several hours or days, depending on the specific product.
4. Weather conditions:-
Apply the grout in suitable weather conditions, avoiding extreme temperatures, humidity, or wind.
5. Surface preparation:-
Ensure the roof slab is clean, dry, and free of contaminants before applying the grout.
6. Thickness:-
Apply the grout at the recommended thickness, usually 1-2 mm, to avoid excessive weight and ensure effective waterproofing.
By following these guidelines and using a high-quality acrylic polymer and cement mixture, you can achieve effective waterproofing for your roof slab.
