DIY Waterproofing and Thermal Insulation plaster instructions
You can make your own handmade thermal and waterproofing plaster in any quantity you need, using Bau Cem (OPC cement), Bauspot Holcer and Bauspot Flas.
Proposed mixture (by weight):
- 60% Bau Cem (white cement) + 15% Bauspot Holcer + 25% Bauspot Flas.
- To the resulting mixture add sand from 1: 2 to 1: 4 depending on the application needs in waterproofing.
- In special cases of stronger waterproofing and better adhesion, you can add to the final mixture (after adding sand) Bauspot Acryl in a quantity of 1:10 (or 1:20 if use of Bauspot Acryl D).
Stirring instructions:
- Mix with a mechanical stirrer. That is, for a quantity of 100kg (before the addition of sand), we need 60kg of Bau Cem, 15kg of Bauspot Holcer and 25kg of Bauspot Flas. To the resulting mixture after mixing, add the sand (1: 2 to 1: 4) and as much water as needed (1: 5-1: 7) to make the final mixture workable.
- Apply directly to the desired surface in the usual way. Before application, make sure that the surfaces are clean and do not contain any type of greases.
Caution. Before the final application, do a test on a smaller surface to check the desired result.
