ISLS18172 Wykamol

Wykamol Dryseal Masonary Protection Cream 3Ltr

  • This effect should not be confused with the "beading" effect often associated with water repellents
  • DRYSEAL has been formulated to penetrate as deeply as possible into porous masonry substrates and this provides optimal protection against the absorption of water and pollutants as well as frost/salt damage
  • The beading effect demonstrates the surface action of a water repellent but may not be significant when assessing a product's overall performance (resistance to rain water penetration under wind pressure).


Product Description

  • The substrate must be in sound condition
  • Absorption of DRYSEAL is a prerequisite for optimal performance
  • plus rising damp and hygroscopic moisture must be remedied first
  • When cleaning, make sure that the masonry is damaged as little as possible
  • Cleaning opens the pores and capillaries, allowing them to absorb the impregnation agent
  • Dependent on the substrate, type and degree of soiling, we recommend the use of various Wykamol surface cleaners (e.g
  • Microtech Biocide)
  • Close expansion and connection joints with elastic joint-sealing compounds
  • It must be ensured that water and damaging salts dissolved in the water cannot penetrate behind the treated surface since this can lead to frost damage (spalling)
  • fine crystalline marble
  • DRYSEAL is not suitable for very dense, nonabsorbent substrates such as e.g
  • Before a water repellent impregnation is carried out, crusts of dirt and pollutants as well as efflorescence, algae and moss must be removed by a suitable cleaning procedure
  • For this reason, the substrate should be as dry as possible
  • If damaging salts are present, a quantitative salt analysis is essential
  • DRYSEAL is especially useful for treating cementitious materials including concrete blockwork as well as natural stone, clay and sand/lime bricks etc
  • Structural defects such as cracks, open joints, etc
  • Chase out defective mortar joints and cracks and repair with a suitable re-pointing mortar
  • This depends on the natural porosity and moisture content of the building material
  • High salt concentrations (especially chlorides, nitrates and sulphates) may lead to damage that cannot be prevented by a water repellent treatmentalone.


High salt concentrations (especially chlorides, nitrates and sulphates) may lead to damage that cannot be prevented by a water repellent treatmentalone. Adjoining surfaces: Due to the thixotropic nature of this product, where it is applied by brush or roller, accidental contamination of non-target surfaces can usually be avoided by taking reasonable care. However, where sprayed (see below), items such as windows and surfaces which are (or will be) varnished or painted, as well as plants, should be covered with polythene sheets. Working Instructions DRYSEAL is applied to building materials undiluted in the desired layer thickness using airless spray equipment, a brush or lambskin roller. Dependent on the absorbency of the substrate, application rates of up to 0.3 l/mÇ can be applied in one working operation, even on vertical surfaces/ceilings without a loss of material. A second application can be carried out at any time but is usually not necessary. Resistance to rain is normally achieved within one hour of application. Full cure up to two weeks depending on climactic conditions. Purchasing Information Product Code: DRYSEAL3 Pack Size: 3 Litres Dryseal advantages: The Application: in a single step. by spray, brush or roller the material can be applied without tricking or dripping the enhanced contact time enables an outstanding penetration depth without waste of material The properties: based on silane/siloxane with lower volatility the consistency provides enhanced contact time rsulting in: The effect: tremendous reduction of water high beading effect high penetration depth allows masonry to breathe high speed penetration of the active content within < 20 min the treated surface remains coatable Dryseal forms a hydrophobic silicone resin network: Dryseal Water absorbtion / unit area: Dryseal out performs other products on the market: Outperforms other creams for hydrophobic impregnation of facades Optimised active content with a special molecular weight distribution Beading effect results guide (see graph 3 above)
