Description
WATER BLOCK M33 is a clear silane water repellent designed to protect a variety of surfaces without altering their natural appearance. It is suitable for natural and artificial stones, tile joints and porous ceramic tiles (cotto), decorative bricks, ceramic roof tiles and porous building surfaces. It exhibits excellent penetration ability and allows surface breathing. Provides excellent protection against nature’s destructive forces and staining. It forms a long lasting, breathable barrier which exhibits superior resistance to water, stains, moisture intrusion, airborne dust, salt, acid rain, alkali, frost and high temperatures.
ADVANTAGES
- Excellent waterproofing properties
- Long lasting protection
- Excellent penetration
- Vapour permeable – allows surface breathing
- Does not alter the natural appearance of the surface applied
- Resistance to temperature variations
- Easy to apply – ready to use material
- Immediate effectiveness
- Interior and exterior use
APPLICATIONS
- Waterproofing and long-lasting protection from staining of natural and artificial stone surfaces. It is suitable for vertical surfaces such as stone facades as well as horizontal ones like verandas and garden stone patios.
- Waterproofing and long-lasting protection from staining of tile joints and porous ceramic tiles (terracotta).
- Waterproofing and protection of decorative bricks.
- Waterproofing and protection from cracking due to moisture intrusion and frost of ceramic roof tiles.
- Waterproofing and protection of white unpolished marble surfaces and colored marble (with compatibility test).
- Waterproofing concrete building surfaces.
- Waterproofing porous building surfaces such as stucco and plaster.
- Priming building surfaces before coating with silane paints.
- It is suitable for interior and exterior horizontal and vertical surfaces. Surfaces treated with WATER BLOCK M33 can be easily cleaned from spots and stains with clean water.

Instructions for use
Substrate preparation
- Surfaces must be dry and clean from dust, unstable material, oil, and rust.
- New surfaces must be cleaned with a wet sponge prior to application.
- Old, stained stone surfaces must be cleaned with CL 17 OXY CLEAN prior to application. Pressure clean wide stone surfaces if needed to remove dirt and use CL 17 OXY CLEAN for stagnant stains.
- Marble stained surfaces must be cleaned with CL 22 OXY CLEAN.
-
Tile joints:
- New tile joints: Allow 7 – 10 days after grouting before applying WATER BLOCK M33. Clean new joints with a wet sponge and allow them to dry out completely.
- Old tile joints: Remove old stains and dirt with CL 17 OXY CLEAN. Wash thoroughly with water and allow them to dry out completely. Hairline grout cracks may be waterproofed with WATER BLOCK M33. Fill bigger cracks with CERAFIX & GROUT.
- Surfaces must be completely dry prior to application.
- Painted surfaces that might be affected by solvents such as sealants, bitumen materials, or polystyrene must be protected prior to application.
Application
- Stir material thoroughly before and during application.
- WATER BLOCK M33 can be applied with a brush, roller, or spray gun (for vertical surfaces). Special attention must be given for even application.
- When applied on very porous substrates, a second coat is recommended. The second coat must be applied wet on wet.
- Windows, doors, plants, etc., must be carefully covered prior to application.
WATER BLOCK M33 when dry is not harmful for humans and the environment.
REMARKS
Due to the wide variety of substrates and environmental conditions, a compatibility test is recommended in an inconspicuous spot prior to full-scale application. Products efficiency is better on sloped surfaces without stagnant water.
CLEANING
Surplus material during application may be removed with a cloth or sponge. Clean tools and equipment immediately after use with white spirit.
