Specifications

• Brand: Kraft Max
• Type: Sponge-faced roughening
• Material: PVC with a sponge surface

Uses

• Roughen and level the surface of the cement plaster before it dries completely.
• Concealing the marks left by the ruler and trowel and giving the wall a uniform texture.
• Wipe away excess grout from the tiles and ceramics after filling the joints.
• Treating minor plaster repairs and integrating them with the surrounding surface.

How to use

• Wet the sponge with water and squeeze it well, as a saturated sponge weakens the plaster surface.
• Start when the plaster has set a little, and move the roughness with light and even circular motions.
• Rinse the sponge whenever mortar accumulates on it so that it does not scratch the surface.
• Wash it with water immediately after finishing work and dry it in the shade before storing.

Frequently Asked Questions

What is the difference between a sponge trowel and a steel trowel?

The iron trowel spreads and polishes the mortar to a smooth surface, while the sponge roughening is used afterward to give a uniform rough texture that helps the following layers to adhere.

When should I start roughening after plastering?

When the plaster begins to solidify and does not stick to the finger when touched lightly, the time varies depending on the ambient temperature and the type of mortar.

Is it suitable for cleaning tile grout?

Yes, a wet sponge roughener is a common tool for wiping away excess grout, with constant rinsing in clean water.
