Will you soon be sailing through the Monstersche Sluis in the Municipality of Maassluis? Then you will immediately notice that this national monument has been substantially refurbished!

Everything was thoroughly cleaned and then all joints were cut out and repaired. Finally, the substrate was treated with our Mavroseal Gel. This impregnating agent protects the surface against:

• dirt adhesion, whitewash and green deposits
• frost and de-icing salts (NEN-EN 13581:2002)
• excellent penetration on already hydrophobized substrates

The lock now has the appearance it deserves and can be used for many years again!
