RC IMPREG 400® 20Kg
In Stock
RC Impreg 400® is a ready made, high performing, colorless, waterbased waterrepellant for porous substrates (concrete, bricks, cementeous plastering, natural stone, roof tiles, …). The RC Impreg 400® is based on a mixture of different increasing molecular weight polymers offering an optimal and lasting waterrepellency effect. RC Impreg 400® is solventless, inflammable, odorless and can be applied to wet, dry or alkaline substrates- even fresh joints. This almost invisble after application product therefore respects the original aspect of the wall but shows a remarkable beading or lotus effect .
Description
Characteristics
RC Impreg 400® is a micro emulsion penetrating easily porous substrates and since containing over alcoxylated oligomers it can be used also at very alkaline materials like fresh joints, plaster, fresh concrete… The products penetrates very well and resists UV from the sun.
- Protects against heavy rainfall and bad weather
- Reduces waterabsorption
- Non filmforming and not altering the aspect of the substrate
- Allows the substrate to breathe (permeable to water vapor)
- Slows down the formation of mildew
- Reduces freeze damage
- Limits the formation of efflorescences
- Prevents premature staining
- Solventless, non toxic, colorless, inflammable
- Excellent ageing, non yellowing
- Can be applied to wet or dry substrates (also fresh joints)
- Impermeability according Karsten tube test (100% after accelerated ageing test)
Surface
The substrate surface must be clean and without dust and mildew. Eventually treat substrate with fungicides prior to RC-Impreg 400® application. Old cracks, bad joints should be repaired prior to application and eventually the use of stone hardener may be needed. In that case it is recommended to wait 3 weeks before using RC-Impreg 400®.
Application
Treatment preferably should be done by wetting the substrate using low pressure, roller or brush and without creating vapor or pulverizing the product. Application should be carried out from bottom to top with horizontal movements. It is convenient and appropriate to proceed twice wet on wet. Using an electric pump with constant pressure is recommended.

RC MORTIER 100 PRO is based on an emulsion of styrene-butadiene polymers in water and is especially formulated for the stability and performance in cement mixes. The product act as adhesive and binder in mortars and slurries and achieves the best bond between old and new substrates. The elasticity and mechanical properties allow much better adhesion to the substrate. In concrete , the product reduces the water cement ratio for better performance and durability. In waterproofing properties, the latex improves the waterproofing and chemical resistance. The RC MORTIER 100 PRO is normally diluted with water depending on the expected performance (see scheme).
